I grew up watching the 700 Club. During my early and middle teen years, when I was a Christian, I watched the show often. One of the things Pat Robertson has always done on the show is offer long distance shout outs to people he claims are being healed. “There’s a woman with lumbago and God is healing you right now.” It’s all quite absurd, of course, but his credulous followers — and I was one of them, but only before I was old enough to give it much thought — lap it up. So what happens when someone says they were healed but the problem returned? Pat blames it on them — or on Satan.
This is one of the standard cons of the faith healing business — you have to have enough faith to make it work. And if it doesn’t work, that proves that you didn’t have enough faith. God always wants to heal you if only you’d prove your faith a little bit more, usually by sending more money to the charlatan telling you so.
