Christians: Why do you believe in a god for whom there is no verifiable evidence/proof?

Because I don't really know what the term "evidence" means. I think evidence is whatever supports ideas that make me feel all warm and fuzzy inside. I trust my own feelings because, in the end, that's all that is really important to me. If your feelings don't accord with mine, it's only because there's something wrong with you and you're going to hell for it. But, of course, that doesn't mean that God doesn't love you.
