By burying their weapons deep in the earth, the Anti-Nephi-Lehies promised the Lord that they would never use them again. Scripture records, “They were firm, and would suffer even unto death rather than commit sin” (Alma 24:19). Their actions demonstrate the complete abandonment of sin following sincere repentance.
President Spencer W. Kimball (1895–1985) taught that abandonment of sins often requires a change in our lifestyle: “In abandoning sin one cannot merely wish for better conditions. He must make them. He may need to come to hate the spotted garments and loathe the sin. He must be certain not only that he has abandoned the sin but that he has changed the situations surrounding the sin. He should avoid the places and conditions and circumstances where the sin occurred, for these could most readily breed it again. He must abandon the people with whom the sin was committed. He may not hate the persons involved but he must avoid them and everything associated with the sin. … He must eliminate anything which would stir the old memories” (The Miracle of Forgiveness [1969], 171–72).
