When Jesus went to pray, let it be thou will and not my will, doesn't that prove he isn't God?

you non Christians have a bad habit of taking scripture out of context, and not fully understand what it means. Also, you are trying to understand something that is WAY beyond what any human mind will ever be able to comprehend. The scripture is about Jesus talking to God his father. Please don't try to understand the concept of the holy trinity because you just can't.
