“Salvation Doth Not Come by the Law Alone”
28 And moreover, I say unto you, that salvation doth not come by the law alone; and were it not for the atonement, which God himself shall make for the sins and iniquities of his people, that they must unavoidably perish, notwithstanding the law of Moses.
President Dallin H. Oaks said:
“Men and women unquestionably have impressive powers and can bring to pass great things. But after all our obedience and good works, we cannot be saved from death or the effects of our individual sins without the grace extended by the Atonement of Jesus Christ. The Book of Mormon makes this clear. It teaches that ‘salvation doth not come by the law alone’ (Mosiah 13:28). In other words, salvation does not come simply by keeping the commandments. ‘By the law no flesh is justified’ (2 Nephi 2:5). Even those who try to obey and serve God with all their heart, might, mind, and strength are ‘unprofitable servants’ (Mosiah 2:21). Man cannot earn his own salvation.”
