In a world of change and decay not even the man of faith can be completely happy. Instinctively he seeks the unchanging and is bereaved at the passing of dear familiar things. Yet much as we may deplore the lack of stability in all earthly things, in a fallen world such as this the very ability to change is a golden treasure, a gift from God of such fabulous worth as to call for constant thanksgiving. For human beings the whole possibility of redemption lies in their ability to change. To move across from one sort of person to another is the essence of repentance; the liar becomes truthful, the thief honest, the lewd pure, the proud humble. The whole moral texture of the life is altered. The thoughts, the desires, the affections are transformed, and the man is no longer what he had been before.
