One important lesson which Madame Guyon learned from her temptations and follies was that of her entire dependence on Divine grace. "I became", she says, "deeply assured of what the prophet hath said, "Except the Lord keep the city, the watchman wakes but in vain." When I looked to thee, O my Lord? thou wast my faithful keeper; thou didst continually defend my heart against all kinds of enemies. But, alas! when left to myself, I was all weakness. How easily did my enemies prevail over me! Let others ascribe their victories to their own fidelity: as for myself, I shall never attribute them to anything else than thy paternal care. I have too often experienced, to my cost, what I should be without thee, to presume in the least on any wisdom or efforts of my own. It is to thee, O God, my Deliverer, that I owe everything! And it is a source of infinite satisfaction, that I am thus indebted to thee."—From the Life of Jeanne Bouvier de la Mothe Guyon, 1648-1717.
