It is necessary that we find God, and God cannot be found in noise and unpeace.... See how Nature--trees, flowers and grass--grow in stillness; how stars, moon and sun run their course in silence. The more we receive through quiet prayer, the more we can give in the activity of our daily lives. In essence, it is not what we say, but what God says to us and through us. All our words are useless if they do not come from within. Words that do not carry the light of Christ only increase the darkness.
