The Law of Moses

Church Educational System
The converted Lamanites understood, as did the righteous Nephites, that salvation did not come through obedience to the law of Moses alone (see Alma 25:16; see also Mosiah 13:27–33). The converted Lamanites understood that the law of Moses served an important purpose until the Savior completed his mission in mortality. Through observance of the law of Moses, these Lamanites could look forward to the coming of Christ, with the law serving as a type, or representation, of Christ and his mission. Thus they kept the law of Moses because they had been commanded to do so, and by living with faith in Christ they received a remission of their sins.
