A story from the Desert Fathers

A certain monk died joyfully because he had never in his life condemned anyone. He was lazy, careless, disinclined to prayer, but throughout his entire life he had never judged anyone. And when he lay dying, he was full of joy. The brethren asked him how he could die so joyfully with all his sins, and he replied, "I have just seen the angels, and they showed me a page with all my many sins. I said to them, 'The Lord said: "Judge not, that ye be not judged." I have never judged anyone and I hope in the mercy of God, that He will not judge me.' And the angels tore up the sheet of paper." Hearing this, the monks wondered at it and learned from it.
