Here's the problem with that, He claimed to be God. When a person claims to be God, you only really have three options.
That person is either crazy, a liar, or actually God.
so he's god, just because he says so?you can't trust the bible
The problem with this idea is that He didn't offer us that option. Jesus claimed to be God. This is why He was killed. Research it and think about it logically: No one gets crucified for urging people to 'love thy neighbour'.
A great moral teacher that claims to be God is either:
a) A liar. Why would I trust the teachings of a man if he bold-faced lied to me? (Especially about something that important...)
b) A lunatic. He claimed to be God. If that's not true, that's a pretty major delusion. Why should I listen to the moral teachings of a crazy person?
c) God. If I was to accept Him at all, I would have to accept Him as God. It's the only viable option available to me. Anything else is not logical.
