According to some estimates, Christians in developed Western countries now represent only 37 percent of believers worldwide. As I travel and also read church history, I have observed a pattern, a strange historical phenomenon of God “moving” geographically from place to place: from the Middle East to Europe to North America to the developing world. My theory is this: God goes where he’s wanted.
That’s a scary thought in a country like the United States, home to five hundred satellite TV channels for diversion and entertainment.
