The following is from the blog of Dr. Gene Veith:
The world’s fastest growing church is that of IRAN.
Despite–or maybe because of–horrific persecution, the number of Christians in Iran has shot up from around 500 in 1979 to hundreds of thousands, maybe over a million, today. More people have become Christians in the last 20 years than have done so in the 13 centuries of Islamic domination combined.
In second place: AFGHANISTAN.
So reports Mark Howard and his sources, linked below.
All of which is instructive for us depressed and discouraged American Christians. If God can build His church in lands of such anti-Christian hostiity as Iran and Afghanistan, He can build it here. And if those Christians can live out their faith in the face of such powerful cultural opposition and government-sponsored persecution, with our far smaller problems, we can too.
