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 in us and through us. All our words are useless if they do not come from within.
And, paraphrasing Max Picard in THE WORLD OF SILENCE:
"The mark of the Divine in God's good creation is preserved by the connection with the world of silence. For Silence is a primary, objective reality, which cannot be traced back to anything else ..." except Love itself. Or, as one of the saints exclaimed, "When the abyss of God's immensity encounters the abyss of our nothingness, God embraces our nothingness!" Abyss calls to abyss in the Silence. Each time we enter into the Silence, we open ourselves to the Beloved in a unique and vulnerable way ... we open the eyes and ears of our heart to the Heart of the universe.
