“Sometimes we wonder why we remember our sins long after we have forsaken them. Why does the sadness for our mistakes at times continue following our repentance? . . . The scriptures do not say that we will forget our forsaken sins in mortality. Rather, they declare that the Lord will forget (see D&C 58:42–43; see also Alma 36:17–19).
“The forsaking of sins implies never returning. Forsaking requires time. To help us, the Lord at times allows the residue of our mistakes to rest in our memory.”
