Reasonable faith

faith...is no blind leap in the dark. Far from it. The Bible teaches that faith is an exercise of reasonable trust in a God who is really there and has proved himself to be completely trustworthy. In fact, it would be utterly unreasonable and irrational not to trust in someone who has proved himself to be infinitely dependable. The whole Bible bears witness to the reality that God has been, is now, and will always be truthful and worthy of our trust. We may not always understand what God is doing or why he is doing it, but we have no good reason to doubt him.
