Many think that when you forgive, the sinner is off the hook. He's not. The forgiving is to get YOU off the hook. Forgive and forget. It takes your mind off of revenge and back to the Lord. As for the sinner, he's still answerable for his own sins. He needs Jesus to relieve him of that.

“In a time of deceit telling the truth is a revolutionary act.”
― George Orwell

It's not over when you lose. It's over when you quit.
