" Only in a world where faith is difficult can faith exist. I don’t have faith in two plus two equals four or in the noonday sun. Those are beyond question. But Scripture describes God as a hidden God. You have to make an effort of faith to find him. There are clues you can follow. “And if that weren’t so, if there were something more or less than clues, it’s difficult for me to understand how we could really be free to make a choice about him. If we had absolute proof instead of clues, then you could no more deny God than you could deny the sun. If we had no evidence at all, you could never get there. God gives us just enough evidence so that those who want him can have him. Those who want to follow the clues will. "
