God created the heavens and the earth “of his own goodness and almighty power, not for the increase of his own happiness.” The ancient theologian Pseudo-Dionysius the Areopagite said that the good, by its very nature, is diffusive of itself. When you are in a good mood, you don’t hide yourself away; on the contrary, you tend to effervesce, communicating your joy. God is the supreme good, and hence God is supremely diffusive of himself; the intensity of his joy is such that it overflows into creation.
