DU,
Further: I am reminded of Jesus walking on water, and Peter attempting to, but failing. Whether or not the story is true matters not. What was being said is that if you doubt what Jesus says, even though you may think you don't, unless it is 100% belief, then you effectively doubt Him. Peter clearly did have some doubt; but as we see later, he came to believe totally in the final analysis. So if he did, so can others overcome that doubt.
