They urge the faithful followers to donate generously and in return the Lord will bring them prosperity.There's no denying some people have prospered handsomely-the pastors themselves. They live like rock stars with huge mansions, private jets, and fancy cars. Their lifestyles are so lavish, six of them have been investigated by the U.S. Senate.One preacher, Paula White, lives in multimillion dollar homes in New York City and Tampa, Florida. And another preacher, Creflo Dollar, gets around in style, flying in private jets to preach around the country. He owns a mansion in an exclusive Atlanta suburb.Not one of them would would sit down for an interview about their opulent lifestyle so INSIDE EDITION's Lisa Guerrero caught up with Creflo Dollar at an event in New York City. She asked him, "How do you justify your million dollar mansions and private jets to your donors?" Dollar had no comment.But when it comes to opulence, few religious leaders compare to Kenneth Copeland. He lives in an 18,000 square foot home outside Ft. Worth, Texas worth $6 million. It has beautiful water views that comes complete with a boat house. But that's not all.Copeland is an avid pilot, and his pride and joy is a $20 million Cessna Citation jet.
