“If the ultimate proof of God is existence itself—which many claim to be the case—then a true state of grace may mean dwelling so fully and completely in her present moment that you are still reading your books and singing your songs when the guards come for you at dawn. The past and the future have no tangible reality in our universe; God’s creation exists moment by moment or not at all, and our only chance at immortality might lie in experiencing each of those moments as the stunning extravagance they actually are.”
