The famed evangelist Dwight Lyman Moody once visited a prison called "The Tombs" to preach to the inmates. After he had finished speaking, Moody visited a number of prisoners in their cells, asking each why he was there. Again and again he received similar replies: "I don't deserve to be here... I was framed... I was falsely accused... I was given an unfair trial..." No one admitted that he was guilty.
At last, Moody found a weeping man holding his face in his hands and asked him what was wrong. "My sins are more than I can bear," the prisoner replied. So relieved was Moody to find an honest man at least that he unthinkingly exclaimed: "Thank God for that!"
[Moody promptly explained that the man's remorse was sufficient for God's forgiveness.]
