We must understand that scripture teaches us to conform to the likeness of Christ in whose image we were made. So, just as there is no salvation without repentance, we are not required to forgive unless the person who has sinned against us is sorry for what he/she has done. In this context, even if the person who has sinned against us apologizes to us seventy times seven, we are to forgive in imitating the meek nature of Jesus Christ
