The Atonement of the Lord Jesus Christ is the heart and core and center of revealed religion.

Elder Bruce R. McConkie Christ and the Creation

23 For all have sinned, and come short of the glory of God;

24 Being justified freely by his grace through the redemption that is in Christ Jesus:

25 Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God;

26 To declare, I say, at this time his righteousness: that he might be just, and the justifier of him which believeth in Jesus.

27 Where is boasting then? It is excluded. By what law? of works? Nay: but by the law of faith.

28 Therefore we conclude that a man is justified by faith without the deeds of the law.

Romans 3:23-28

Note that when Paul speaks of the law in verse 28, he is referring to the Law of Moses and the term, “without” in the original Greek is “apart from” or “without intervention of”.

When this true faith takes root in a person, it inevitably leads to repentance. Amulek taught that the Savior’s sacrifice would “bring salvation to all those who shall believe on his name; this being the intent of this last sacrifice, to bring about the bowels of mercy, which overpowereth justice, and bringeth about means unto men that they may have faith unto repentance” (Alma 34:15; emphasis added).

To be complete, however, repentance requires a covenant of obedience. This is the covenant expressed by Benjamin’s people “to do [God’s] will, and to be obedient to his commandments” (Mosiah 5:5). This is the covenant witnessed by baptism in water (see Mosiah 18:10), sometimes referred to in the scriptures as the “baptism of repentance” or “baptism unto repentance,” inasmuch as it is the culminating step, the capstone of our repentance (see, for example, Acts 19:4; Alma 7:14; 9:27; D&C 107:20).

Then, as promised, the Lord baptizes us “with fire and with the Holy Ghost” (3 Nephi 9:20). Nephi phrased it this way: “For the gate by which ye should enter is repentance and baptism by water; and then cometh a remission of your sins by fire and by the Holy Ghost” (2 Nephi 31:17).1 Having thus relied “upon the merits of him who is mighty to save” (2 Nephi 31:19), we are “quickened in the inner man” (Moses 6:65) and, if not yet fully born again, then certainly well into the path of spiritual rebirth.

Now, the Lord cautions us to take heed since “there is a possibility that man may fall from grace” (D&C 20:32), even those who are sanctified (see vv. 32–34). As Nephi counseled: “Ye must press forward with a steadfastness in Christ, having a perfect brightness of hope, and a love of God and of all men. Wherefore, if ye shall press forward, feasting upon the word of Christ, and endure to the end, behold, thus saith the Father: Ye shall have eternal life” (2 Nephi 31:20).

You may ask, Why doesn’t this mighty change happen more quickly with me? You should remember that the remarkable examples of King Benjamin’s people, Alma, and some others in scripture are just that—remarkable and not typical.2 For most of us, the changes are more gradual and occur over time. Being born again, unlike our physical birth, is more a process than an event. And engaging in that process is the central purpose of mortality.

At the same time, let us not justify ourselves in a casual effort. Let us not be content to retain some disposition to do evil. Let us worthily partake of the sacrament each week and continue to draw upon the Holy Spirit to root out the last vestiges of impurity within us. I testify that as you continue in the path of spiritual rebirth, the atoning grace of Jesus Christ will take away your sins and the stain of those sins in you, temptations will lose their appeal, and through Christ you will become holy, as He and our Father are holy.

I know Jesus Christ as the living, resurrected Son of God.

“[I] know that justification through the grace of our Lord and Savior Jesus Christ is just and true;

“And [I] know also, that sanctification through the grace of our Lord and Savior Jesus Christ is just and true, to all those who love and serve God with all their mights, minds, and strength” (D&C 20:30–31; see also Moroni 10:32–33).

Although the word “justify” has several meanings, its main meaning in the latter-day scriptures is inseparably intertwined with the concepts of grace (Rom. 3:28; Gal. 2:16; 2 Ne. 2:5; Mosiah 14:11; D&C 20:30; Moses 6:60), faith, repentance, righteousness, and sanctification.

Justification is a scriptural metaphor drawn from the courts of law: a judge justifies an accused person by declaring or pronouncing that person innocent. Likewise, God may treat a person as being “not guilty” of sin. All mortals individually need to be justified because they fall short of perfect obedience to God, becoming “carnal, sensual, and devilish” through transgression (Moses 5:13; Mosiah 16:3), are “cut off” from God, and are in jeopardy of becoming “miserable forever” (2 Ne. 2:5). In this plight, they of themselves cannot be justified through subsequent obedience to the law and cannot change their own nature to become obedient. Furthermore, they are severed from the source of the divine power that can change, or sanctify, them (2 Ne. 9:5-9).

However, through the Atonement of Jesus Christ, when men, women, or children have faith in Jesus, are truly penitent, call upon his name, and are baptized, they become eligible for the redeeming grace extended through Jesus Christ. In this sense they become justified. This is given as a gift by grace, since fallen man must rely “alone upon the merits of Christ” (1 Ne. 10:6; Moro. 6:4). The faith by which one receives this grace manifests itself in an active determination to follow Christ in all things. It is demonstrated by obedience to the commandments to repent and be baptized, followed by a life of submission, obedience, and service to God and others (2 Ne. 31:16-20; Moro. 8:25-26; see Gospel of Jesus Christ).

Justification directly opens the way to sanctification by establishing a “right” relationship of mortals with God. Thus, God, without denying justice, can bless them with the sanctifying power of the Holy Ghost (Mosiah 5:1-2; 3 Ne. 27:20). Justification starts the believer on the path toward righteousness.

Justification

Author: Colin B. Douglas, The Encyclopedia of Mormonism

What then is the law of justification? It is simply this: “All covenants, contracts, bonds, obligations, oaths, vows, performances, connections, associations, or expectations” (D. & C. 132:7), in which men must abide to be saved and exalted, must be entered into and performed in righteousness so that the Holy Spirit can justify the candidate for salvation in what has been done. (1 Ne. 16:2; Jac. 2:13-14; Alma 41:15; D. & C. 98; 132:1, 62.) An act that is justified by the Spirit is one that is sealed by the Holy Spirit of Promise, or in other words, ratified and approved by the Holy Ghost. This law of justification is the provision the Lord has placed in the gospel to assure that no unrighteous performance will be binding on earth and in heaven, and that no person will add to his position or glory in the hereafter by gaining an unearned blessing.

As with all other doctrines of salvation, justification is available because of the atoning sacrifice of Christ, but it becomes operative in the life of an individual only on conditions of personal righteousness. As Paul taught, men are not justified by the works of the Mosaic law alone any more than men are saved by those works alone. The grace of God, manifest through the infinite and eternal atonement wrought by his Son, makes justification a living reality for those who seek righteousness. (Isa. 53:11; Mosiah 14:11.)

Elder Bruce R. McConkie

“Justification,” Mormon Doctrine (Bookcraft, 1966)

To be sanctified through the blood of Christ is to become clean, pure, and holy. If justification removes the punishment for past sin, then sanctification removes the stain or effects of sin.

Elder D. Todd Christofferson

Justification and Sanctification,” Ensign, Jun 2001, 18

For by the water ye keep the commandment; by the Spirit ye are justified, and by the blood ye are sanctified.

Moses 6:60
