The mortal mission, death, and resurrection of Jesus Christ provided for the unconditional resurrection of all mankind. The Lord’s death and resurrection brings all mankind into the presence of God, where they will be judged of their works in life.
When brought into God’s presence, those who have accepted the Lord’s offer of forgiveness of past sins by forsaking them will be able to withstand his presence.
To the degree that they sacrificed to know more about him and serve others in life, they will receive eternal joy. They will be filled with joy everlasting in the knowledge that, throughout life, they always searched for, grew into, and rejoiced in all available improvement and truly did everything they could to help others.
Those who rejected the Lord’s offer of forgiveness of past sins, or who turned away from him after receiving it, will experience eternal torment. The wicked person’s insistence on being less than what they knew they could be will fill them with pain more excruciating than they can imagine.
The test of mortality is not whether one has claimed to believe in God or not. The test is whether they truly believed in God. To claim to believe in God is easy. To actually believe in him requires you to desire and act according to your professed belief.
Furthermore, you can believe in what you call God without having beliefs that accord in any way with what he has actually said to you.
To truly believe in God requires conforming to what God has actually said to you, as demonstrated by your desires, beliefs, and actions.
The scriptures that attest to the assertions made in this section are so concise, numerous, and repetitive that, rather than interleave them in the text, a selection of them is given below:
...ye must all stand before the judgment‐seat of Christ, yea, every soul who belongs to the whole human family of Adam; and ye must stand to be judged of your works, whether they be good or evil; (Mormon 3:20)
9 Wherefore, [Jesus] is the firstfruits unto God, inasmuch as he shall make intercession for all the children of men; and they that believe in him shall be saved.
10 And because of the intercession for all, all men come unto God; wherefore, they stand in the presence of him, to be judged of him according to the truth and holiness which is in him.... (2 Nephi 2)
But God ceaseth not to be God, and mercy claimeth the penitent, and mercy cometh because of the atonement; and the atonement bringeth to pass the resurrection of the dead; and the resurrection of the dead bringeth back men into the presence of God; and thus they are restored into his presence, to be judged according to their works, according to the law and justice. (Alma 42:23)
And no unclean thing can enter into his kingdom; therefore nothing entereth into his rest save it be those who have washed their garments in my blood, because of their faith, and the repentance of all their sins, and their faithfulness unto the end. (3 Nephi 27:19)
14 And my Father sent me that I might be lifted up upon the cross; and after that I had been lifted up upon the cross, that I might draw all men unto me, that as I have been lifted up by men even so should men be lifted up by the Father, to stand before me, to be judged of their works, whether they be good or whether they be evil—
15 And for this cause have I been lifted up; therefore, according to the power of the Father I will draw all men unto me, that they may be judged according to their works. 16 And it shall come to pass, that whoso repenteth and is baptized in my name shall be filled; and if he endureth to the end, behold, him will I hold guiltless before my Father at that day when I shall stand to judge the world.
17 And he that endureth not unto the end, the same is he that is also hewn down and cast into the fire, from whence they can no more return, because of the justice of the Father. (3 Nephi 27)
4 And even unto the great and last day, when all people, and all kindreds, and all nations and tongues shall stand before God, to be judged of their works, whether they be good or whether they be evil—
5 If they be good, to the resurrection of everlasting life; and if they be evil, to the resurrection of damnation; being on a parallel, the one on the one hand and the other on the other hand, according to the mercy, and the justice, and the holiness which is in Christ, who was before the world began. (3 Nephi 26)
5 Know ye that ye must come to the knowledge of your fathers, and repent of all your sins and iniquities, and believe in Jesus Christ, that he is the Son of God, and that he was slain by the Jews, and by the power of the Father he hath risen again, whereby he hath gained the victory over the grave; and also in him is the sting of death swallowed up.
6 And he bringeth to pass the resurrection of the dead, whereby man must be raised to stand before his judgment‐ seat. (Mormon 7)
And thus he shall 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)
And he hath brought to pass the redemption of the world, whereby he that is found guiltless before him at the judgment day hath it given unto him to dwell in the presence of God in his kingdom, to sing ceaseless praises with the choirs above, unto the Father, and unto the Son, and unto the Holy Ghost, which are one God, in a state of happiness which hath no end. (Mormon 7:7)
33 For behold, there is a wo pronounced upon him who listeth to obey that spirit; for if he listeth to obey him, and remaineth and dieth in his sins, the same drinketh damnation to his own soul; for he receiveth for his wages an everlasting punishment, having transgressed the law of God contrary to his own knowledge.
38 Therefore if that man repenteth not, and remaineth and dieth an enemy to God, the demands of divine justice do awaken his immortal soul to a lively sense of his own guilt, which doth cause him to shrink from the presence of the Lord, and doth fill his breast with guilt, and pain, and anguish, which is like an unquenchable fire, whose flame ascendeth up forever and ever.
39 And now I say unto you, that mercy hath no claim on that man; therefore his final doom is to endure a never‐ ending torment. (Mosiah 2)
17 But behold, the resurrection of Christ redeemeth mankind, yea, even all mankind, and bringeth them back into the presence of the Lord.
18 Yea, and it bringeth to pass the condition of repentance, that whosoever repenteth the same is not hewn down and cast into the fire; but whosoever repenteth not is hewn down and cast into the fire; and there cometh upon them again a spiritual death, yea, a second death, for they are cut off again as to things pertaining to righteousness. (Helaman 14)
45 O, my beloved brethren, turn away from your sins; shake off the chains of him that would bind you fast; come unto that God who is the rock of your salvation.
46 Prepare your souls for that glorious day when justice shall be administered unto the righteous, even the day of judgment, that ye may not shrink with awful fear; that ye may not remember your awful guilt in perfectness, and be constrained to exclaim: Holy, holy are thy judgments, O Lord God Almighty—but I know my guilt; I transgressed thy law, and my transgressions are mine; and the devil hath obtained me, that I am a prey to his awful misery. (2 Nephi 9)
These scriptures and the others attesting to the same truths are worthy of study and consideration, but they are clear enough that additional commentary would not be helpful.
