Hey, you sound like me throughout my late teens and through to the end of my twenties! I too thought I was too smart to believe the Bible is true, but after accepting Jesus as my Savior, I read the Bible, completely, and although there are parts that still don't make sense to me, the big picture makes total sense. It's a matter of first you believe, and then you will see. Your angry outbursts in regard to spiritual matters is actually a good sign; those who remain quiet in their disbelief in God are the ones who are more likely to never believe the truth of the Bible.
