Exley is part of a movement of Christians loosely organized by radio broadcasts and websites, independent of churches and convinced by their reading of the

To get the word out, they're using billboards and bus stop benches, traveling caravans of RVs and volunteers passing out pamphlets on street corners. Cities from Bridgeport, Conn., to Little Rock, Ark.
