Who needs forgiveness and who needs to forgive

There is no difference, for all have sinned and fall short of the glory of God, and are justified freely by His grace through the redemption that came by Christ Jesus.  God resented Him as a sacrifice of atonement, through faith in His blood.  He did this to demonstrate His justice, because in His forbearance He had left the sins committed beforehand unpunished He did it to demonstrate His justice at the present time, so as to be just and the one who justifies those who have faith in Jesus.  Romans 3:23-26
