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.
Mystery: it is all around us, and we do not know it. But sometimes when we give it time and space, whether in deep peace or great anguish, it will come up behind us, or meet us face to face, or move within us, changing the way we see everything, and filling our hearts with joy and an upspringing of love that needs no direct object because everything is its object.
