“If you do not accuse each other, God will not accuse you. If you have no accuser you will enter heaven, and if you will follow the revelations and instructions which God gives you through me, I will take you into heaven as my back load. If you will not accuse me, I will not accuse you. If you will throw a cloak of charity over my sins, I will over yours—for charity covereth a multitude of sins. What many people call sin is not sin; I do many things to break down superstition, and I will break it down.”
History of the Church, 4:445 (7 November 1841)

Context: People are often unreasonable and self-centered. Forgive them anyway. If you are kind, people may accuse you of ulterior motives. Be kind anyway. If you are honest, people may cheat you. Be honest anyway. If you find happiness, people may be jealous. Be happy anyway. The good you do today may be forgotten tomorrow. Do good anyway. Give the world the best you have and it may never be enough. Give your best anyway. For you see, in the end, it is between you and God. It was never between you and them anyway.

“Accuse the other side of that which you are guilty.”
