Not strictly true, because in this universe God appears to have delegated control to the laws of nature and human free will.
God seems a bit like the Cheshire Cat then, who as you may recall, gradually faded away. If God delegates, how do we know that he's there? Guess, I suppose.
As blue has just said, it also seems to get rid of the omnis. I suppose God could stop gravity working, if you fell out of the window, but he's an equal opportunity kind of guy, so lets you fall. Errm, so what's the point in God?
