At a certain point in your life you need to believe in something. These preachers fill that emptiness in many peoples lives. I don't think it's a bad thing for people who desperately need direction, reassurance and acceptance. It gives them a structure to live by and keeps them out of trouble. I believe that these evangles that where touched and inspired by God honestly believe it to be true. I think people do have callings. The problem happens when these same people start believing they are somehow chosen above all others and start decieving themselves consciously or subconsciously by using God as a device for their OWN benefit and doing things in his name. Scary.
