My friends, ask gladness from God. Be glad as children, as birds in the sky. And let man’s sin not disturb you in your efforts, do not fear that it will dampen your endeavor and keep it from being fulfilled, do not say, “Sin is strong, impiety is strong, the bad environment is strong, and we are lonely and powerless, the bad environment will dampen us and keep our good endeavor from being fulfilled.” Flee from such despondency, my children! There is only one salvation for you: take yourself up, and make yourself responsible for all the sins of men. For indeed it is so, my friend, and the moment you make yourself sincerely responsible for everything and everyone, you will see at once that it is really so, that it is you who are guilty on behalf of all and for all. Whereas by shifting your own laziness and powerlessness onto others, you will end by sharing in Satan’s pride and murmuring against God. I think thus of Satan’s pride: it is difficult for us on earth to comprehend it, and therefore, how easy it is to fall into error and partake of it, thinking, moreover, that we are doing something great and beautiful.
–The Elder Zosima, in Fyodor Dostoevsky, The Brothers Karamazov, translated by Richard Pevear and Larissa Volokhonsky
