That would be one of the major reasons why disabled people are the least churched group in America.

I once had a class with a seminary professor (now a bishop) who is legally blind. Our tradition isn't really into faith healing; we do laying on of hands and anointing, but not with the expectation that it means you're going to be walking out of there without your crutches. (Now, sometimes miracles do happen ... but if they happened reliably every time, they wouldn't be miracles.) He told a story of how confounded a pastor from a faith-healing tradition was that he couldn't just magically "fix" the "problem".
