Left to ourselves we tend immediately to reduce God to manageable terms. We want to get Him where we can use Him, or at least know where He is when we need Him. We want a God we can in some measure control. We need the feeling of security that comes from knowing what God is like, and what He is like is of course a composite of all the religious pictures we have seen, all the best people we have known or heard about, and all the sublime ideas we have entertained.
