In a hotel conference room in Denizli, Turkey, about 60 Iranians sing along to songs praising Jesus mixed with Iranian pop music. When the music stops, American pastor Karl Vickery preaches with the help of a Persian translator.
"I'm not famous or rich. But I know Jesus. I have Jesus," he says, with a Southern drawl. The Farsi-speaking Christian converts shout "Hallelujah!" and clap.
Vickery, who's part of a visiting delegation from Beaumont, Texas, then offers to pray for each person in the room.
