Let me offer my limited view on Asia as someone who has been there and has Asian in laws.
1. Money. All the richest businessman are Christian due to converting when studying overseas or seeing Christian countries as rich (Korea, Muricah) It is obvious God is blessing them. In non-Christian cultures that are open you go to the temple where you are being blessed. Superstition is massive and very in our favor.
2. Very good for culture as the commies now see. The Christians don't revolt, they render unto Caesar whatbis Caesar's, and they behave morally which is GREAT for society. Even the Pagans and Atheists in China know fornication and lies and theft is bad.
3. Very compatible with Chinese morals. Family first, work hard, and seek wisdom. Confucius actually makes an unattributed quote from Ecclesiastes (written 200 years prior) in his analects. It also makes automatic alliances with fellow Christians overseas.
This is gonna be GREAT for us if the Chinese advanxe our cause.
