Merry Christmas everyone! Celebrating the best news that came in the smallest package, Jesus entering the world so that God might dwell among men.

Today went according to plan! I was able to sleep at home for my daytime naps, which made it easy to fall asleep. I also took my first nap in this experiment on the train tonight. In all my sleeps, I was able to go to sleep, then wake up when I was supposed to, and not oversleep, while still functioning fine throughout the day. After my incident with oversleeping yesterday, today I took extra care in not delaying getting out of bed when my alarm went off. It turned out well.

My midnight nap returned to a quality similar to the first day, and I woke up feeling refreshed and awake. I managed to stay awake till my scheduled 4am nap, feeling only a little drowsy. This time, instead of having only one dim light during my awake time, to simulate daytime and to avoid falling asleep, I turned the main room lights on and kept them on till I went to bed again. I spent the time making some travel plans in the upcoming few days spent at my dad's place. I didn't eat anything between my midnight nap and my 4am nap this time.

Up until my 8am nap, I caught up on some email, watched some TV, and did some light aerobic exercises to pass the time. I spent the daytime reading, writing emails and watching TV. For breakfast I had yoghurt and cereal, and for lunch I ate some bread and rice with stew.

The whole morning, I suffered fog of brain which led to slightly slurred speech, but my bladder control and appetite were both functioning normally. Another sensation I thought I'd mention is that I feel quite cold even indoors. I don't know if it's because it's currently winter, or because I'm having issues with thermostatic homeostasis, or both, or something else altogether, but maybe I'll be able to interpret the sensation better as time goes on.

After my 4pm nap, we set out for Ginza for a dinner my dad had booked from a while back. It would have been nice to have been attend the Christmas Eve service at church, but my dad had booked already before I'd shared that idea, and it's kind of difficult changing reservations around this time of year. Well, I have this Sunday to visit the church I was planning on going to. In the meantime, the dinner itself was amazing. It was a Japanese style meal that came in several courses (lost count) and it was themed around fish and seafood. We had sashimi, fish head miso soup, grilled fish, scallops, and rice cake dessert with abalone, amongst many other dishes. Probably not the best idea to eat such extravagance when I'm adjusting to a brand new sleep regime, but it was an experience worth every bite.

In hindsight, we all regretted not dressing up more formally for today :P


In the end, I was still able to sleep reasonably soundly so that was a relief. The only issue was, the dinner finished at 7:40 and it would be awkward to pass out at the dinner table so I had to either delay my sleep till I got back home, or sleep on the train. It just so happened that at 7:58pm, we transferred to a train that we rode to the terminal station, and the trip was exactly 29 minutes, and I managed to get a seat. So I took my nap on the train. I recollect hearing the announcement for the first stop after I'd prepared to take my nap, but nothing else after that till the train pulled up at the terminal stop, which suggests I managed to get at least some shut eye. I consider that pretty impressive, since I have never been in the habit of napping before commencing this sleep experiment. Even if I terminate this sleep experiment for whatever reason, I am still glad to have gained insight into the art of taking short naps.

Though it's only the second day of the experiment, I overslept. I don't think the cause was because I was physically incapable of getting up though - a skill of mine that has been brought to my conscious awareness during this experiment worked against me this time.

The first nap went all according to plan, getting up around 12:30am. But I got really hungry, so I ate five inari sushis, and some cut raw vegetables. After that, I took a nap at 2am. It was only halfway between my first and second planned naps, but as I mentioned in my experimental design, I allowed for extra naps during the transition period. So I went to bed at 2am and set my countdown timer for 25 minutes later. But when I turned the alarm off after 25 minutes, I didn't get up straight away - a big mistake. From how it felt like to me, not even half a minute after turning the alarm off, I must have fallen asleep again. I woke up of my own accord at 7:14, turning a half hour nap into a five our sleep. At 2 in the morning today I got really sleepy, but in my opinion, much more so than I should have been at this stage of my transition period. I think the not insignificant amount of food I ate an hour prior to going to bed contributed at least in part. I will plan the quantity and variety of food I eat in the time period I'm usually asleep, namely between my 12am nap and my 8am nap, so that I don't make myself sleepier than I will already naturally become.

Because of that, I skipped my 8am scheduled nap and waited until my 12pm nap. Today, my 12pm, 4pm and 8pm naps were taken in the car, because we went on a road trip to German Village in Chiba Prefecture to see the illuminations. According to the official Japanese page, this is in the top 3 illuminations in the Kanto region.






I used an inflatable pillow (a thoughtful farewell present from Australia) and an eye mask while sleeping, but it was definitely not as nice an experience as a proper bed. I may have not even properly fallen asleep even once, though mentally I was still able to function the whole day. Right now, I feel quite ok, and I've been able to converse quite normally with my parents, and even felt capable of driving (though dad drove the whole time so I didn't need to). My appetite has been good, and I really really want to eat a lot of meat, but knowing that it will lead to increased sleep requirement, I refrained.


Only being the second day, I was a bit disappointed I wasn't able to stick to the routine. But the experimental timeframe I set for myself was 10 days, so I'm going to stick it out till that period is over. Assuming I don't oversleep a nap again tomorrow, I expect to feel pretty dead at least mentally tomorrow. From here on, I need to watch what I eat during the night time period much more closely so I don't induce feelings of sleepiness through giving my body extra load in digestion.

Polyphasic sleep cycle - Day 1

Progress at-a-glance
End of day 1*
  • Mental alertness: 9
  • Physical energy level: 9
  • Quality of sleep: 10

*On this scale, 10 represents my original state prior to beginning this experiment.

I've reached the end of my first 24 hour period, and I'm proud to say so far so good. I've successfully stuck to my sleep regime, hitting the sack no more than ten minutes out from any of my designated sleep times. I'm feeling surprisingly normal, in comparison to my hypothesis for the first day. I am going to note that during the entire 24 hours, I minimised (but not eliminated) meat intake, and ate a lot of fruit and vegetables, but it's too early to be able to comment how much if at all that influenced sleep quality. Also, I can't say for sure, but from my conscious perception it appears that every nap, I'm asleep within five minutes of laying my head on the pillow. Can't say for certain yet whether it has any link with my low animal product diet.

First nap was better than expected. I went to bed only minutes after finishing my experimental design writeup, which didn't leave me much time to collect my thoughts and calm down a bit, so there were a million (ok maybe around 8 or so) thought processes buzzing around in my head when I hit the sack. Naturally I was a bit concerned about whether I'd be able to fall asleep, but I was actually awoken by my alarm 25 minutes later, which meant I did actually fall asleep eventually. I promptly climbed out of bed after I woke up, with only a hint of fog of brain. I spent my waking hours updating my blog, replying to emails, and doing a bit of reading.

On my second nap, I fell asleep straight away. It seems I don't seem to be having any trouble falling asleep, which is a good thing. But after waking up, fog of brain affected me more noticeably. I spent my waking hours catching up on some unwatched anime, then ate a bit, and fought to stay awake by physically keeping my body moving for the final stretch before my scheduled 8am nap.

After waking up from my third nap, I felt like a million dollars. I had my first dream since starting the polyphasic sleep cycle, which means I hit REM sleep! I didn't expect to reach it so fast. Also, I woke up of my own accord one and a half minutes before my countdown time went off. My dad, mum and I all did some light aerobics exercises (テレビ体操) before I had breakfast, then I went to church with my parents. We visited the Funabashi Bible Baptist Church (船橋聖書バプテスト教会) for the first time, and it was a good experience. Everyone was really friendly, the sermon was firmly centered in the gospel message, and the congregation was a surprisingly large 100 or so people. I didn't have trouble with nodding off during the sermon or anything, though I must say it was a good sermon that again reinforced the necessity of the gospel for Christians and non Christians alike.

The church being so close to my dad's home, I quickly ducked back for my fourth scheduled nap of the day at 12pm, and rejoined them in time to have lunch together. Once again I felt pretty good, quite far from how I'd expect to feel with only two hours of sleep over the past 28 hours. We watched a play based off the book of Esther that the church held, before going home and winding down. Throughout this leg of the day, there was no hint of fog of brain.

My fifth nap was quite uneventful. I woke up feeling fairly decent, the same as my previous nap. Something I thought I should mention, though, is that my dad said I was acting significantly more out of it because of my new sleep pattern. I was surprised to hear it, because by my own sense of alertness and physical energy, I felt close to my normal state.

On my final sleep for the day, I experienced for the first time the sensation that Steve reports on his 22nd day, more specifically, that it felt like I was asleep for much longer than I actually was. I felt a slight sense of disorientation when my timer went off slightly before 8:30pm, because my body told me I had slept for quite some time whilst the time on my phone indicated I had only been asleep for 25 minutes, as planned. I don't think it's a bad thing when your body feels like it's rested for longer than you actually did.

One concern I had was that during the period between my first nap and my fourth one, I found that my urge to relieve my bladder doubled in frequency compared to prior to commencing the polyphasic sleep cycle. But the volume I would relieve each time was close to half of my usual. The symptoms possibly suggest that cell signalling to my detrussor muscle was abnormal during that time. From after my fifth nap and onwards, those symptoms resolved itself, and my toilet trips became regular again. Throughout the 24 hours, my bowel movements matched my usual cycle.

Looking forward to how the second day will progress!

Polyphasic sleep cycle - Day 0

So my little(?) experiment begins here. I explained in my previous post my reasons and motivation for embarking upon this challenge, as well as what exactly I will be embarking upon. In this post, I'll outline my strategy on how I actually plan to go about doing it. The rationale for my experimental design is based on my research into past recorded attempts of the Uberman sleep cycle, much of which is summarised in my previous post.

Goal: to change from a monophasic 7 hour sleep cycle to a polyphasic sleep cycle sleeping for 30 minute sessions at regular four hour intervals, for a total of six times (i.e. three hours' sleep) per day.

Experimental timeframe: Ten days will be allowed for the sleep pattern transition period. After the initial ten day period, I will evaluate the viability of continuing the polyphasic sleep cycle based upon my state of mental and physical functionality in comparison to prior to starting the experiment.

Sleep schedule: I will be taking six lots of 30 minute naps* each 24 hour period, evenly spaced out every four hours. More specifically, I will be sleeping 25 minutes beginning at 12am, 4am, 8am, 12pm, 4pm, and 8pm every day. I will set a countdown timer before I go to bed, and I will get up after 25 minutes irrespective of my sleep (if at all) quality. I will strive to keep every bedtime within 10 minutes of the predetermined timings. My first sleep begins in 5 minutes.
During the initial transition period of ten days only, I have allowed the addition of an extra nap time between the 12am and 4am naps where necessary, inspired by Steva Pavlina's attempt of the Uberman sleep cycle. 


*The thirty minutes is calculated from the time I begin preparing to sleep, until after I come to my senses and climb out of bed. So the time spent with my head on the pillow is actually only 25 minutes, and my time spent asleep will be even less. This time designation was also inspired by Steve Pavlina's Uberman sleep cycle blog, after I suspected being asleep for a whole thirty minutes might actually be counterproductive.

Diet: From this point on until at least the termination of my polyphasic sleep cycle regime, I will be on an almost vegetarian diet, though I can't promise I won't eat meat altogether.

Predicted course of events: The first 24 hours, I will be slightly tired, but otherwise normal. The next 48-72 hours, I will be a walking zombie. The remaining time over the ten day experimental period, I will slowly transition from zombie-like status to regaining normal brain clarity.

Detailed breakdown of experimental design:
     The Uberman sleep cycle is a well established and widely accepted method amongst the polyphasic sleepers community. I have chosen to try out this pattern of sleep for two main reasons, firstly because it appears to come with a truckload of advantages and only slight disadvantages, and secondly because it happens to fit into my usual daily routine.

     If you want to read up on the advantages and disadvantages of the Uberman sleep cycle, just refer to my previous post or type the search term into Google, and you will get more than enough results so I won't bother adding to the vast amount of content already available. If I were to do a comparative analysis between the advantages and disadvantages of the more common various polyphasic sleep cycle variations, I would point out that the distinct lack of a core sleep block was the clincher for me. From a theoretical perspective, I agree with the thinking that retaining a core block of sleep in your regime encourages oversleeping in the long run. From a practical perspective, it frees up more time to be awake doing stuff!

     As for compatibility with my usual daily routine, I worked it out like this. Until winter holidays end (Jan 5th), I will have a 100% flexible schedule which allows me freedom to make the sleep cycle transition. After winter semester begins, from Monday to Friday, I can sneak in a nap before class begins at 8:30, then during my 11:40-12:40 lunch break I can sneak in another nap, and after classes finish at 3:50, it's the next scheduled nap time. Tuesdays and Thursdays I have Aikido training from 5:30-7:30pm, Wednesday there is a prayer meeting at Tama church from 6:00-7:00, none of which interfere with my 8pm nap. On Saturday, I'm at Aikido training from 10:30-12:00, so my noon nap time might be slightly delayed, but only by a bit. The morning service at Tama church is from 10:15-11:50 ish, which is fine, but if I want to stay to have lunch, I may need to sneak off somewhere for a quick 30 minute shut eye between end of the service and lunch time. There is also an afternoon service for younger people from 5:30-7pm, which fits into the schedule just fine. I'll just need to watch out for the occasional social event or Christian event and such, which may overlap with my 8pm sleep time. Though if I let people know in advance, disappearing from the gathering for half an hour if needed shouldn't be too big of a deal.

     If I were to specify what would be the make or break of this experiment, it would be self-discipline. In my opinion, my background knowledge is satisfactory (considering the scarcity of material available on this subject), the experimental design is realistic yet well set out, my personal motivations for making the sleep cycle switch are clear and rational, and my current life circumstances are conducive to carrying out such an experiment. But whether my willpower to last till the end will rule over my mounting desire to sleep over the next few days, I don't know. I think I'll take the advice I read on Steve's blog regarding navy SEALs mentality - during the toughest period, just focus on progressing one leg at a time.

Polyphasic sleep cycle - Prephase

Lately, I stumbled across this article outlining patterns of sleep different to the conventional monophasic and/or biphasic sleep patterns that the majority of adults adopt. The clear advantage of picking these alternate sleep cycles is requiring less hours of sleep per day to obtain the same benefits as sleeping the conventional 8 hours. Always-short-on-time me got thinking after reading it, and thus came about the inception of this upcoming personal experiment/project.

The aforementioned alternate sleep patterns vary amongst themselves depending on whether there is a "core" block of sleep to supplement the nap-length sleep times, as well as on the number of sleeps per day (and the duration of each sleep). But for one who is contemplating adopting one of these patterns, the more important factor is compatibility - whether a routine that involves pre-planned naps during the daytime fits into your lifestyle. The Uberman sleep cycle which involves sleeping a mere total of 3 hours a day, just happens to fit into my usual schedule well, as I've outlined further down. Thus began more serious research on whether it's worth having a crack at it.

There is a lot of controversy around the interwebs surrounding polyphasic sleep cycles with low sleep hours such as the Uberman sleep cycle, not in the least being the sparsity of success stories or nonexistence of studies on the long term health effects. Everybody knows how crucial sleep is to maintaining mental and physical health, and very few people are willing to risk their health - or that of potential test subjects - by subjecting them(selves) to a pattern of sleep that is too good to be true. Next to no one actually sleeps like that in the real world, at least in modern society. And there are many reports on the web of people who have tried and failed, putting out the conclusion that it's just not humanly compatible, for whatever reason.

However, why the article I mentioned at the beginning stopped me and got me thinking, was because it actually mentions success stories of real people who have been using the Uberman cycle for many years with no reported adverse effects. However, what made me hesitant was that just being aware of these success stories didn't address some big concerns I had for trying it out myself.

That all changed when I stumbled across Steve Pavlina's blog. Assuming that it is not made up, Steve successfully applied and maintained the Uberman sleep cycle for half a year, and the best part of all, he documented his day to day experiences during that period of time in great detail. I read through his entire half year log, and what impressed upon me the most was that he declared that he had no negative health effects long term (half a year, and then five years later), and he provided possible hypotheses for why that might have been along the way. He brings up, and addresses, worries and concerns I had about trying it out for myself, and gave rational responses to commonplace skepticism surrounding the Uberman sleep cycle. These include*:

Not only does he address my initial concerns, but along the way he offers a list of potential factors that affect your success rate at adopting this sleep cycle.

The above is what tipped the scales for me, and what compelled me to give it a try while I'm still in winter holidays and I can afford to fail a personal sleep experiment. This post is intended as the preface into why I began this little experiment. For the methodology i.e. what it will look like in practice, refer to my next post.

I'll leave you with a quote from Steve, taking on a different perspective to the skeptics.
"I dont think the biggest risk of polyphasic sleep is that youll fail to adapt to it. I think the biggest risk is what might happen if you actually succeed."

Apologetics seminar in Japan

Yesterday, I was invited by a Thai friend from the same program as me, to attend an apologetics seminar held at Fuchu Calvary Chapel. It was delivered by a special guest from Hawaii with an Okinawan name and lineage called Pat (sorry, I forgot his last name >.<). He was apparently well versed in the area of apologetics, and the title he earned was proved true by what he taught today. Coming from Australia, it wasn't the first time I'd heard or read these things, but since coming to Japan, it has been my first time. Having already been 9 months, it was a welcome refresher for my faith also, being reminded that it's by faith we are saved, and that the faith we have in Christ is sure faith. I thought I would share here what I learned, for everyone's edification.

Historical reliability of the gospels
Jesus' ministry is commonly held to have taken place between 30-33AD. Some skeptics assert that the gospels do not represent the oldest record of Jesus Christ, but that they were written after the lifetime of the eyewitnesses. The implications are that they are not eyewitness accounts, but mostly legends and mythology.

According to historians, it takes 120 years after a major event for legends and myths to develop. That is because all the eyewitnesses must die first. However, if the accounts were written in the lifetime of the eyewitnesses, they are not legend or myth, but actual records of what happened. That's because the eyewitnesses can affirm or deny the things that have been written down. Made up accounts of what happened wouldn't last very long once the eyewitnesses found them.

The earliest biography of Siddhārtha Gautama, commonly known as the Buddha, comes 400 years after his life. That means much of what is written about Buddha is actually based on legends and mythology. And many people think the same way about the gospels.

What is worth noting, is that we have strong evidence that the gospels were in fact written by eyewitnesses. That means these accounts are not legends or myths; they are true stories.

Dating of the gospels
  • William F Albright, a Jewish non-Christian dean of archaeology, concluded that every book of the New Testament was written by a baptized Jew between AD40-80.
  • Bishop John Robinson, a liberal critic and founder of the "Death of God" movement, changed his position on the date of the gospels at the end of his life, newly asserting that the gospels of Matthew, Mark, Luke and John were likely all written between 40-65AD.
  • Traditionally, the gospels are dated as follows:
    • Mark, 60AD
    • Matthew & Luke, 70AD
    • John, 70/90AD

Date of the gospels: internal evidence
  • In all four gospels, Jesus predicts the destruction of the temple (occurred 70AD) but its fulfilment is not mentioned once. This was the most important building in the history of Israel, and its absence in the accounts suggests the books' completion prior to the event.
  • We know Paul was killed by Emperor Nero in 64AD, so his letters have all been written prior to that time.
  • Paul quotes the gospel of Luke (1Ti 5:18), meaning the gospel of Luke was completed before Paul died.
  • Acts never mentions the Jewish War (66AD), when the nation of Israel was completely dismantled.
  • Acts never mentions the death of the three most important early church leaders, showing that Luke completed the book of Acts before 62AD

Date of the gospels: external evidence
  • There have been over 5000 Ancient Greek manuscripts discovered to date
  • The Rylands papyri found in Egypt, dated 120AD, contains a fragment of John. To reach Egypt by that time, it must have been written much earlier.
  • Clement of Rome 90AD and Ignatius 107AD quote many of the books of the New Testament as Scripture
  • Polycarp 120AD, disciple of John, informs us by his writings that the canon we have today had already been confirmed in his time

Archaeology and the gospels
  • Luke names 34 countries, 54 cities and 9 islands very accurately
  • He also mentions the names of government officials, whose names sounded very strange for people of that time, but recent archaeological evidence affirms all of their existence
  • William Ramsey spent many years in Israel trying to prove Acts was unhistorical, but at the end of his studies, he highly appraised the calibre of Luke's writing, and became a Christian
  • John mentions the pool of Bethesda in his gospel, and we have discovered this pool recently in israel

The historicity of Jesus
His existence is recorded in secular history records, both Jewish and Roman. The notable thing is, these people were enemies of Christianity historically. By their acknowledgement that such things took place, the enemies of Christianity affirmed the accuracy of the gospels.

The Jewish Talmud (completed 300AD) speaks of a historical Jesus and tries to explain Jesus' miracles by attributing them to sorcery and magic. What is interesting, is that by not denying these phenomenon, it affirms that they really took place. Also recorded is Jesus' crucifixion, and the death of five apostles. Thallus mentions in his third book that the earth covered by darkness when Jesus was crucified. Tacitus (115AD) through calling Christians evil by documenting all that they were doing, affirms that the events and the people of the NT were real.

In court today, if your enemy affirms your story, that is the most powerful evidence.

Q&A Session
Using the conclusion we established in the first session, namely the historical reliability of the gospels, we proceeded to answer mostly prepared, and some impromptu, questions on the topic of apologetics.

  1. Why do Christians do wars?
The use of force is necessary to keep the peace. In the book of Revelation, it is written that Jesus will one day return and wage war against evil. If the Son of God must use force to defeat evil and bring peace, so must we.

At the same time, the Bible gives guidelines on when and how to use force. Violence must be as a last resort, and even then, only proportional means to win, and not to decimate the country, and the civilians must be spared.

Some people use Matthew 5:38-42 to argue that Jesus preached pacifism, by insisting that one must not lash back against a wicked man. However, this teaching does not prohibit the use of violence. In Jewish times, a slap on the right cheek means "I despise you", in this case, for being a Christian. So the passage actually says that if you are despised for being a Christian, don't fight back, turn the other cheek instead. It does not prohibit the use of force to stop someone who is defenseless from being harmed.

However, the Bible does not endorse murdering people who are not Christians. Sadly, this has happened in history. That is man's fault, it is directly in contrary to God's commands, and it should never have happened.

  1. Doesn't a monotheistic belief cause people to be narrow minded and intolerant?
This question strikes close to the heart of the Japanese people, who believe a polytheistic belief is more welcoming and less exclusive.

Firstly, it is correct to say that a monotheistic belief is narrow and exclusive - because that is the nature of truth. Truth by its very nature is narrow and exclusive. It excludes all other possibilities, by calling them fallacy. So it can be said that anyone who believes the truth is narrow minded and intolerant of what is not truth.

Accordingly, when the Bible teaches that Jesus is the Son of God, any religion that denies that is wrong. And if Jesus is the Son of God, and he taught that he is the only way to life, then every other way to God is wrong.

  1. I can believe in God, but I can't accept why I need to believe in Jesus.
The bible teaches that God has given us the perfect law, and put it in our hearts. Romans 2 says that Christians and non-Christians alike have the moral law within them. Everyone knows we have not lived perfectly according to God's law, and that makes us all sinners.

Someone needs to die for sin, but no one except God is perfect enough to be able to. However, God cannot die. So Jesus came to earth as a man, in order to become the perfect sacrifice for sin, and to die the death we deserve in our place to pay the price. No other religion can offer that, and that is why we need to believe in Jesus.

  1. Why do people suffer if there is a just and loving God?
If God doesn't exist, life is ultimately without meaning and without purpose, and your suffering means nothing. But because God exists, our life has meaning and purpose.

James 1:2 tells us to endure trials of various kinds with joy, because it builds our character to be more like Christ. In the Hebrews 5:8, it says Christ learned obedience through suffering, so we should expect to go through the same thing.

Some skeptics ask question of why children who are born crippled have to suffer and live meaningless lives. But how do you know they live meaningless lives? Some of the greatest lessons we have ever learned come from people who have suffered tremendously. Nagai Takashi from Nagasaki who suffered radiation position from the bomb and was paralysed for much of his life, but through his suffering he wrote several inspirational books that are read all over the world. Furthermore, Christians look forward to that day when Jesus comes back, because there will be no more suffering.

On the other hand, what message does an atheist have to give to these crippled people? They offer no substance, no hope, and no meaning, not just for cripples, but for anyone. Just suffer in a meaningless life, die and disappear.

How do we know the Christian gospel is truth, and not just a fairy tale? Because our faith is based on a real Jesus who really rose from the dead. Only Christianity can offer any message of hope for those who suffer.

  1. What will happen to someone who dies without ever hearing the gospel?
This is possibly the most difficult answer for Japanese people to hear. It is not an easy answer to stomach, but sometimes truth is just that.

Romans 1:19-23 says every passing day points to a creator, from the telescope to the microscope. How much more complex is the human brain than a computer, which no one would ever believe came about sponaneously or accidentally?

Romans 2:12-16 says that everyone has the witness of God through their conscience, and we all know right from wrong. For example, murder, adultery, and stealing are universal sins unanimously considered to be damaging to society. The biggest sin of all, is denying the creator God who made us and gives us purpose in life. And for those who don't believe in Jesus and accept his death on the cross for their sin, they will be condemned to hell.

Having said that, Acts 10 mentions a God fearing Roman soldier named Cornelius who didn't know Jesus but wanted to know God. In the end, God used Peter to share the gospel with him, and he believed. Whoever wants to know God, God will somehow get the message to them.

Hebrews 9:27 tells us that there are no more chances to repent and believe in Jesus after you die.

  1. I have mounting doubts even after say I believe. Does my faith need to be reevaluated?
Doubts are actually a good thing!

"The unexamined life is not worth living." - Socrates

For us Christians, the unexamined faith is not worth living.
God is big enough to answer any questions we have concerning him. Other religions say don't ask, just believe, but Jesus and the apostles invited others to ask questions and seek answers. So when you have questions, it should motivate you to seek answers! Many Christians who do not ask questions about their faith, are those who fall away when their faith is challenged.

  1. Why are there so many divisions within Christianity like Catholicism and Protestantism? Which one is right?
Truth is measured by the Bible, not by man-made parameters. We measure whether a church or a denomination is consistent by the Bible. The Bible, God's truth, is never wrong, but human interpretation is not perfect (1Corinthians 13:12, this world is like seeing through a mirror unclearly).

We do not have perfect interpretations so we do not have perfect understanding. But we should agree on the essentials such as there is one God, the Trinity, and the Son of God Jesus Christ. On the non essentials, denominations are allowed to disagree like how to conduct baptism.

As for Protestantism and Catholicism, the former initially came about as a result of the latter drifting away from Biblical teaching. If you read up on Martin Luther (not Martin Luther King) in the 16th century, you will learn why. I didn't bother writing down what's already on Wikipedia.

  1. How do people who lived and died before Jesus came to earth get saved?
Just believing in God through our knowledge of the creation and our conscience (Q5) is not enough. We need special revelation to know God, and that special revelation came through the nation of Israel.

Israel had the system of offering sacrifices for sin. That sacrifice was an unblemished lamb that would shed its blood for the sins of the people. The lamb itself did not save people from sin, but it was a prophetic symbol of the Saviour whom people would put their faith in.

Foreigners outside of Israel still had a chance to hear the gospel. Many came to Israel to learn about God. In other cases such as Jonah, God sent a prophet from Israel to reveal himself to the foreign countries.

  1. What age of children are saved?
The Bible talks about an "age of accountability". After a certain age, children are able to understand and respond to God's expectations. In Israel, the Bar Mitzvah ritual takes place at 12 years of age, but that is more tradition and not something taught in the Bible. The bible doesn't specify when exactly the "age of accountability" is. The actual timing may depend person to person.

  1. Will a spiritual revival come to Japan?
400 years ago, Christianity thrived in Japan (Edo period). As we study the lives of the Christians back then, they were faithful to Christ, enduring persecution and even dying in his name.

An age of revival may not have yet come, but before one will come, God's people must be faithful to God's call in the Bible. Revival begins in God's household. Let's pray for revival to sweep Japan, and pray that it would begin within.

Autumn semester: Complete

Sorry for the long period of nonresponsiveness! As of this week, exams are over, results have been returned, and holidays begin!

It's been no short of hectic this semester, since the results from this semester and this semester only get sent to our prospective universities. Everyone has been studying the hardest they've been to date, and arguably, the hardest they ever will this entire academic year. There is a final winter semester left beginning in January before we graduate, but we need no more than a passing grade, regardless of which university we are aiming for next year, so I'm anticipating a lot less studying and a lot more enjoying from here. 

Exam schedule for end of semester exams

There was a weekend in the middle of our four day exam period. We were so grateful for it! - till the details of which exams took place when came out. Literally ALL of the time consuming subjects were held before the weekend, while those that took only a fraction of the effort to study for were after it. At the time, everyone was like, I don't even…!
Later I realised that the exams that take the longest for us to write, also take the longest for the teachers to mark. And all of the exams were scheduled to be marked and returned to us the day after exam period was over. Since the exams containing the most content would also take the longest time for the teachers to mark, it made sense that they were given the weekend to have more time. I can sympathise with the teachers here in Japan who operate under such high pressure.

So in continuation of recording my results for future record, and sharing them with those back in Oz:
Kanji writing/reading
99
Japanese grammar
99
Japanese reading
92
Japanese listening
100
Japanese speaking
90
Japanese composition
88
Politicoeconomics
8586
Japanese history
100
Japanese studies
90.4

Not even worth mentioning is how the marking scheme for the politicoeconomics exam has once again been altered post-exam. Should I mention that this time, he also modified the exam itself, halfway through the exam? The topics we learned about this semester were identical to those covered by Japanese high school students - or at least we would have learned them, if we'd actually been taught it properly. Why couldn't he use an established textbook to structure the syllabus and learning content instead of talking about something completely irrelevant to the handouts he gives us each lesson and then expects us to retain both the handout content and what he was talking about? This is the only exam for which I stayed up beyond my normal bedtime, three days in a row, before the exam itself. And it still ends up as my lowest scoring subject. Enough venting from previous posts, so I'll leave it here.

I might mention here that there is negligible difference in final university preferences between getting a 90 and getting a 100. The grading system used by the school here is that 90 and above equates to an "S", 80-89 is an "A", 70-79 is "B", 60-69 is "C", and below 60 is fail. So ultimately, that means the two 100 mark subjects aren't anything special, and instead, for two subjects I failed to get an S grading. According to the teachers, I lose my chances of getting into Tokyo University, since their minimum expectation is apparently an S grading for all subjects.
I'm not disappointed or anything by that, since at least most of the universities in Japan have a high standard of education. If anything, it saves me the temptation of boasting in my own ability by starting to think I did it all by myself, and forgetting God's grace and His sovereignty. I do admit that whenever I contemplated studying at TokyoU these past few months, it only ever fed into my pride, which is already a major spiritual struggle to deal with. I'd appreciate your prayers for an awareness of how I as a sinner have nothing to boast about before God, and to remember how I depend upon the grace of Christ poured out on the cross for my sin.


Sorry for my long absence from my blog, and thanks for all your prayers through that time guys :)
