The Benefit of Doubt: Coming to Terms with Faith in a Postmodern Era by Pete Enns.
Doubt forces us to look at who we think God is. It makes us face whether we really trust HIM, or whether we trust what we have made God to be. Doubting God is painful and frightening because we think we are leaving God behind. But doubt—real hard deep unnerving uncomfortable scary doubt—helps us to see that, maybe we have made God into our own image. We come to discover, slowly but surely, that the “faith” we are losing is not faith in God. It is actually in the idea of God that we surround ourselves with.
