Jehovah the Eternal Judge

34 And now I bid unto all, farewell. I soon go to rest in the paradise of God, until my spirit and body shall again reunite, and I am brought forth triumphant through the air, to meet you before the pleasing bar of the great Jehovah, the Eternal Judge of both quick and dead. Amen. ( Moroni 10)

The Judgment Seat of Christ

20 And these things doth the Spirit manifest unto me; therefore I write unto you all. And for this cause I write unto you, that ye may know that 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;
21 And also that ye may believe the gospel of Jesus Christ, which ye shall have among you; and also that the Jews, the covenant people of the Lord, shall have other witness besides him whom they saw and heard, that Jesus, whom they slew, was the very Christ and the very God.
22 And I would that I could persuade all ye ends of the earth to repent and prepare to stand before the judgment-seat of Christ . (Mormon 3)

The Twelve Apostles Shall Judge Twelve Tribes

9 And he said unto me: Thou rememberest the twelve apostles of the Lamb? Behold they are they who shall judge the twelve tribes of Israel ; wherefore, the twelve ministers of thy seed shall be judged of them; for ye are of the house of Israel .
10 And these twelve ministers whom thou beholdest shall judge thy seed. And, behold, they are righteous forever; for because of their faith in the Lamb of God their garments are made white in his blood. (1 Nephi 12)

18 Yea, behold, I write unto all the ends of the earth; yea, unto you, twelve tribes of Israel , who shall be judged according to your works by the twelve whom Jesus chose to be his disciples in the land of Jerusalem.
19 And I write also unto the remnant of this people, who shall also be judged by the twelve whom Jesus chose in this land ; and they shall be judged by the other twelve whom Jesus chose in the land of Jerusalem . (Mormon 3)

The Justice of Our God

14 Wherefore, we shall have a perfect knowledge of all our guilt, and our uncleanness, and our nakedness; and the righteous shall have a perfect knowledge of their enjoyment, and their righteousness, being clothed with purity, yea, even with the robe of righteousness.
15 And it shall come to pass that when all men shall have passed from this first death unto life, insomuch as they have become immortal, they must appear before the judgment-seat of the Holy One of Israel; and then cometh the judgment, and then must they be judged according to the holy judgment of God.
16 And assuredly, as the Lord liveth, for the Lord God hath spoken it, and it is his eternal word, which cannot pass away, that they who are righteous shall be righteous still, and they who are filthy shall be filthy still; wherefore, they who are filthy are the devil and his angels; and they shall go away into everlasting fire, prepared for them; and their torment is as a lake of fire and brimstone, whose flame ascendeth up forever and ever and has no end.
17 O the greatness and the justice of our God ! For he executeth all his words, and they have gone forth out of his mouth, and his law must be fulfilled.
18 But, behold, the righteous, the saints of the Holy One of Israel, they who have believed in the Holy One of Israel, they who have endured the crosses of the world, and despised the shame of it, they shall inherit the kingdom of God, which was prepared for them from the foundation of the world, and their joy shall be full forever. (2 Nephi 9)
