It is as simple as , the TV did not tell him that he couldn't walk on water.

My take is: he was not poisoned by the modern world into believing what he could or could not do. He did not think boundaries existed because he never for once considered those were even there, he was a pure form of a human being. He could just walk into any situation he wanted and have no boundaries. He had never seen a lake and did not know he could sink on it, so he didn't.
"You keep him in here, and make sure HE doesn't leave!"

I think that the end shows that Chance, like the Road Runner (who also defies gravity), he will not sink until he understands his dilemma.
You don't think anything - you stole that line directly from Roger Ebert's review.

I think it was for that old saying, 'he could do no wrong, he could walk on water' meaning of course he can do wrong but people idolize too much so much in fact they make them God-like, when they are not.
If my answers frighten you then you should cease asking scary questions.

What I gathered was that the last 15 minutes exposed what the film is about. Comedicaly, or dramatic Chance was 'The Antichrist'.

His name was chance. He was simply very lucky. That's what the ending shows, in line with the entire movie.
