In a dream, Martin Luther found himself being attacked by Satan. The devil unrolled a long scroll containing a list of Luther’s sins, and held it before him. On reaching the end of the scroll Luther asked the devil, “Is that all?” “No,” came the reply, and a second scroll was thrust in front of him. Then, after a second came a third. But now the devil had no more. “You’ve forgotten something,” Luther exclaimed triumphiantly. “Quickly write on each of them, ‘The blood of Jesus Christ God’s son cleanses us from all sins.'”
