Matthew 18:32-33 “Then his master, after he had called him, said to him, ‘You wicked servant! I forgave you all that debt because you begged me.  Should you not also have had compassion on your fellow servant, just as I had pity on you?’”
The master had forgiven a servant who owed a large sum of money, but the servant was not willing to forgive a man who owed him a much smaller sum. Jesus went on to say that God will not be pleased with us if we do this. He will rebuke us. Jesus has forgiven us, and we MUST rely on the Holy Spirit to forgive others.
