In everything we do, in every aspect of our lives, in our thinking and our feelings, all areas, we need to infuse those areas with the Light of God. If we do that, we will experience a wonderful sense of joy. This quality is valued by the angels because it is so very special when humanity uses its free will to replace the energy of darkness with the Light of God, especially out of love. Each time a person does this in his or her own life, it is cause for the angels to rejoice.
Silence brings us far beyond soundlessness, it quiets our senses and spirit and tunes our heart for a deep and delicate listening. For, silence is a primal language which speaks and listens from the heart. It is not the only language through which we communicate with God, but it is a necessary second language since the knowledge of God is received in divine silence. Like all other languages, silence is easily forgotten without practice and discipline.
