Not a being at all

The opening sentences of Karen Armstrong's new book, The Case for God, will certainly keep me reading:

We are talking far too much about God these days, and what we say is often facile. In our democratic society, we think that the concept of God should be easy and that religion ought to be readily accessible to anybody. "That book was really hard!" readers have told me reproachfully, shaking their heads in faint reproof. "Of course it was!" I want to reply. "It was about God." But many find this puzzling. Surely everybody knows what God is: the Supreme Being, a divine Personality, who created the world and everything in it. They look perplexed if you point out that it is inaccurate to call God the Supreme Being because God is not a being at all, and that we really don't understand what we mean when we say that he is "good," "wise," or "intelligent." People of faith admit in theory that God is utterly transcendent, but they seem sometimes to assume that they know exactly who "he" is and what he thinks, loves, and expects (ix).
