My understanding is that China had a growing Christian presence in the late 19th century and and early 20th (some of y'all will know of Hudson Taylor and the China Inland Mission, for example). The organized church in China, however, was mostly caught up in the pre-trib rapture dispensationalism being popularized at the time, and was caught completely off-guard by the Communist takeover in the 1940s, leading to a huge loss of faith and falling away.
Just sayin. Things could get a lot worse for us over a long period of time before we get any relief from on high....
