How can I find out if I believe in God?

I'm not sure. My upbringing points to a God, but education and intellect say otherwise. I was raised in a Christian family, but I don't know if I believe in a God that sends people to hell because he didn't like the way the person believed. I think it's unfair of a God to send people to hell because someone was Buddhist or Hindu and not Christian. I may not agree with Protestant Christianity. I am not sure.
