Part of the inner world of everyone is this sense of emptiness, unease, incompleteness, and I believe that this in itself is a word from God, that this is the sound that God's voice makes in a world that has explained him away. In such a world, I suspect that maybe God speaks to us most clearly through his silence, his absence, so that we know him best through our missing him.
