Just when we supposed that he was about to come to the defense of this ""world-governing, background God,"" he dismisses such a God, leaving us with the demonic, leaving us room to affirm our own doubts and perplexities, leaving us with a harsher formulation than we might have ventured, leaving us attentive to what he is going to do next and to where he is going to lead us. Because by now we are following him."" --From the ""Introduction.""
