As C.S. Lewis would say-are they lying, are they mad, or are they telling the truth? People do lie sometimes, and perhaps my difficulty in letting go of Christianity despite a mountain of evidence against it is that my prior on people making up stories is too low. It would take an awful lot of psychosis to make someone believe that a leg had regrown, but again, people do go insane. But is there a way to get a sense of how likely/unlikely this is? With Pascal's Wager on the table, it's not enough to say there's ~40% chance Christianity is true, that's less than half, it's probably wrong. Rejecting it without constant fear would take near certainty that accounts like this one are fraudulant or deceived.
