Grace refers to divine help or strength, given through the bounteous mercy and love of Jesus Christ. “It is through the grace of the Lord Jesus, made possible by his atoning sacrifice, that mankind will be raised in immortality, every person receiving his body from the grave in a condition of everlasting life. It is likewise through the grace of the Lord that individuals, through faith in the atonement of Jesus Christ and repentance of their sins, receive strength and assistance to do good works that they otherwise would not be able to maintain if left to their own means. This grace is an enabling power that allows men and women to lay hold on eternal life and exaltation after they have expended their own best efforts.
“Divine grace is needed by every soul in consequence of the fall of Adam and also because of man’s weaknesses and shortcomings. However, grace cannot suffice without total effort on the part of the recipient. Hence the explanation, ‘It is by grace that we are saved, after all we can do’ (2 Ne. 25:23). It is truly the grace of Jesus Christ that makes salvation possible. This principle is expressed in Jesus’ parable of the vine and the branches (John 15:1–11). See also John 1:12–17; Eph. 2:8–9; Philip. 4:13; D&C 93:11–14)” (Bible Dictionary, “Grace,” 697).
Elder Dallin H. Oaks of the Quorum of the Twelve Apostles discussed the effects of grace and how grace is an important doctrine for members of The Church of Jesus Christ of Latter-day Saints:
“Some Christians accuse Latter-day Saints … of denying the grace of God through claiming they can earn their own salvation. We answer this accusation with the words of two Book of Mormon prophets. Nephi taught, ‘For we labor diligently … to persuade our children … to believe in Christ, and to be reconciled to God; for we know that it is by grace that we are saved, after all we can do’ (2 Nephi 25:23). And what is ‘all we can do’? It surely includes repentance (see Alma 24:11) and baptism, keeping the commandments, and enduring to the end. Moroni pleaded, ‘Yea, come unto Christ, and be perfected in him, and deny yourselves of all ungodliness; and if ye shall deny yourselves of all ungodliness, and love God with all your might, mind and strength, then is his grace sufficient for you, that by his grace ye may be perfect in Christ’ (Moroni 10:32).
“We are not saved in our sins, as by being unconditionally saved through confessing Christ and then, inevitably, committing sins in our remaining lives (see Alma 11:36–37). We are saved from our sins (see Helaman 5:10) by a weekly renewal of our repentance and cleansing through the grace of God and His blessed plan of salvation (see 3 Nephi 9:20–22)” (in Conference Report, Apr. 1998, 77; or Ensign, May 1998, 56).
