Agape is our greatest weapon against sin

At some ideas you stand perplexed, especially at the sight of human sins, uncertain whether to combat it by force or by human love. Always decide, "I will combat it with human love." If you make up your mind about that once and for all, you can conquer the whole world. Loving humility is a terrible force; it is the strongest of all things and there is nothing like it. - Dostoyevsky - The Brothers Karamazov
