You are wrong - Nowhere is a Christian told in the Bible to that we need to "prove" anything, we are told to "proclaim", if God chooses to open your mind to the Truth then he will, if he doesn't he doesn't.

The Bible is evidence for me, but not to your liking or standard, and your rational for not believing is that you don't like what God does, which sounds more like a response from my 6 year old than one from an adult.

Go ahead and believe in the Spaghetti Monster - your unbelief is yours, and does not affect my belief in any way, shape or form. And why do you care what I believe ? And we all have a source of truth - it either comes from within or from external sources. The Bible is a spiritual book, and spiritually dead people are not going to understand it.
