Silence is no passive thing. It is a vibrant presence which fills any vacuum in sound and conveys its own living quality. Most of us know the truth of the phrase "the silence that sounds," and the old adage "silence is golden" means more than just that it is safe or wise. It means that it is golden in the sense of being filled with light.
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.
