If you are penitent, you love. And if you love you are of God. All things are atoned for, all things are saved by love. If I, a sinner even as you are, am tender with you and have pity on you, how much more will God have pity upon you. Love is such a priceless treasure that you can redeem the whole world by it, and cleanse not only your own sins but the sins of others.

Book II, ch. 3 (trans. Constance Garnett). - The Brothers Karamazov (1879–1880)
