The psalmist trusting in the Lord prays for God’s great love and mercy from of old to be remembered so that youthful sin and rebellious ways might be forgotten. While the Lord remembering us in love erases the memory of our rebellion we do not easily forget our own folly or foolishness or willful acts of insolence and indulgence. Memories as fresh as the day they were recorded return accusing and condemning bringing guilt and shame. The enemy that triumphs over me lives in my own heart and mind as I remember what God has forgotten as if God still holds it against me. Forgiveness freely offered is never fully received as long as I continue to hold myself accountable for the sin God forgot long ago. Since the way of the Lord is first and foremost forgiveness the instruction of the sinner begins with trusting the Lord, faithful and loving, and in doing so forgiving self. It does not mean forgive and forget which I think is beyond our ability, or at least mine. What we can do is remember forgiveness whenever we remember what God has forgotten and in so doing be finally free from youthful sins and rebellious ways.
