It is necessary that we find God, who cannot be found in noise and unpeace. God is the friend of silence. 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.
Only the Spirit of the Holy One can impart to the human spirit the knowledge of the holy. Yet as electric power flows only through a conductor, so the Spirit flows through Truth and must find some measure of Truth in the mind before It can illuminate the heart. Faith wakes at the voice of truth but responds to no other sound... Still, there must be humble penitence in the heart before Truth can produce faith.
