What help is it, in short, to know a God with whom we have nothing to do? Rather, our knowledge should serve first to teach us fear and reverence; secondly, with it as our guide and teacher, we should learn to seek every good from him, and, having received it, to credit it to his account. For how can the thought of God penetrate your mind without your realizing immediately that, since you are his handiwork, you have been made over and bound to his command by right of creation, that you owe your life to him?–that whatever you undertake, whatever you do, ought to be ascribed to him?
