To believe in God is to long for His existence and, further, it is to act as if he existed; it is to live by this longing and to make it the inner spring of our action. This longing or hunger for divinity begets hope, hope begets faith, and faith and hope beget charity. Of this divine longing is born our sense of beauty, of finality, of goodness.
