Japan has it's spiritual problems, the biggest one I fear is that pornography is part of daily life. The single man prefer porn, the women don't such perverts, therefore it breaks down.

In China, the phone is like a third hand, i.e can't live without it. Because everyone has cheap unlimited Internet data, you have Internet with you all the time.

It's popular to call people through an app, instead of using your real phone number. This all in one app is called Wechat, with it you can pay your bills, order a taxi, order food, blog how much you love your country, send files, and send money. Every store, person has a QR barcode, scan it with your phone, and pay.

I already could not get a shuttle bus from the airport because they did not take paper money. All it takes is your bank account frozen and you can't buy anything.

Second A lot of math is not practical in daily life, the basics are often more than enough.

Is much of calculus, and statistics, important, yes in a specific context, but not in daily life, hence why so many never apply it and never master it.

To walk with God means that you and God are in agreement about your life. “Can two walk together, except they be agreed?” (Amos 3:3, KJV).

When the Bible speaks of "walking," it often refers to a lifestyle. We can walk in the ways of the world as well (2 Kings 8:27; Ephesians 2:2; Colossians 3:7). In the New Testament, walking with God is often called "walking in the Spirit" (Galatians 5:16; Romans 8:4).
Walking with God also means we cannot also walk with evil people as companions (Psalm 1:1-3).

Because Psalms is poetry, when translating into english, the King James Version people asked William Shakespeare to help! As thanks, they hid his name in Psalms 46!

The KJV bible was published in 1611, at this time Shakespeare was... 46 years old! He was born on 1564.

Now if we go to psalm 46, and start from verse 1, count down "46" words, you will land on the word "Shake", now go to the last verse, and do the same, you will land on the word.. Spear!
