I, even I, am He who blots out your transgressions for My own sake; and I will not remember your sins.—Isaiah 43:25
One of the old German devotional philosophers took the position that God loves to forgive big sins more than He does little sins because the bigger the sin, the more glory accrues to Him for his forgiveness. I remember the writer went on to say that not only does God forgive sins and enjoy doing it, but as soon as He has forgiven them, He forgets them and trusts the person just as if he or she had never sinned. I share his view that God not only forgives great sins as readily as little ones, but once He has forgiven them He starts anew right there and never brings up the old sins again....
When a person makes a mistake and has to be forgiven, the shadow may hang over him or her because it is hard for other people to forget. But when God forgives, He begins the new page right there, and then the devil runs up and says, "What about this person's past?" God replies: "What past? There is no past. We started out fresh when he came to Me and I forgave him" Faith Beyond Reason, 112.
"Lord, this concept is so foreign to our human understanding and our human way of doing things. Your grace in forgiving—and forgetting— is beyond our comprehension. But I worship You for it today. Amen."
