There are many stories of forgiveness, of how there are people who have forgiven others for truly terrible things and these testimonies move the masses since we see in it a divine work that can not be done by a human unless God puts it in the heart. However, among all those stories there is one that is superior in every sense of the word and it is the Father to forgive us.
The Bible says:
38 Be it known unto you therefore, men and brethren, that through this man is preached unto you the forgiveness of sins:
39 And by him all that believe are justified from all things, from which ye could not be justified by the law of Moses.
