FORT WORTH  Onstage before thousands of believers weighed down by debt and economic insecurity, Kenneth and Gloria Copeland and their all-star lineup of “prosperity gospel” preachers delighted the crowd with anecdotes about the luxurious lives they had attained by following the Word of God.

Private airplanes and boats. A motorcycle sent by an anonymous supporter. Vacations in Hawaii and cruises in Alaska. Designer handbags. A ring of emeralds and diamonds.

“God knows where the money is, and he knows how to get the money to you,” preached Mrs. Copeland, dressed in a crisp pants ensemble like those worn by C.E.O.’s.

Even in an economic downturn, preachers in the “prosperity gospel” movement are drawing sizable, adoring audiences. Their message  that if you have sufficient faith in God and the Bible and donate generously, God will multiply your offerings a hundredfold  is reassuring to many in hard times.
