I have not read your Mormon book, but the original Scriptures, Yah’shua Messiah says He is not the judge.
John 5:45 “But don't think that it is I who will be your accuser before the Father. Do you know who will accuse you? Moshe, the very one you have counted on! 46 For if you really believed Moshe, you would believe me; because it was about me that he wrote. 47 But if you don't believe what he wrote, how are you going to believe what I say?”
Yah'shua our Messiah paid the penalty for our sins. Revenge belongs to YHVH, the Father & He only.
Mormon prophets also teach that Joseph Smith is our judge, and we cannot enter the “celestial Kingdom” (Heaven) without Smith’s permission.
“[There is] no salvation without accepting Joseph Smith. If Joseph Smith was verily a prophet, and if he told the truth...no man can reject that testimony without incurring the most dreadful consequences, for he cannot enter the kingdom of God”
- Prophet Joseph Fielding Smith, Doctrines of Salvation, v. 1, p. 190
“No man or woman in this dispensation will ever enter into the celestial kingdom of God without the consent of Joseph Smith...every man and woman must have the certificate of Joseph Smith, junior, as a passport to their entrance into the mansion where God and Christ are”
- Prophet Brigham Young, Journal of Discourses, v. 7, p. 289
“For hundreds of years the world was wrapped in a veil of spiritual darkness, until there was not one fundamental truth belonging to the place of salvation ...Joseph Smith declared that in the year 1820 the Lord revealed to him that all the ‘Christian’ churches were in error, teaching for commandments the doctrines of men.”
- Prophet Joseph Fielding Smith, Doctrines of Salvation, v. 3, p. 282
“He that confesseth not that Jesus has come in the flesh and sent Joseph Smith with the fullness of the Gospel to this generation, is not of God, but is anti-christ”
- Prophet Brigham Young, Journal of Discourses, v. 9, p. 312
“If we get our salvation, we shall have to pass by him [Joseph Smith]; if we enter our glory, it will be through the authority he has received. We cannot get around him [Joseph Smith]”
- Apostle George Q. Cannon, Melchizedek Priesthood Study Guide, 1988, p. 142
“I tell you, Joseph holds the keys, and none of us can get into the celestial kingdom without passing by him. We have not got rid of him, but he stands there as the sentinel, holding the keys of the kingdom of God.. But I tell you, the pinch will be with those that have mingled with us, stood next to us, weighed our spirits, tried us, and proven us: there will be a pinch, in my view, to get past them. The others, perhaps, will say, If brother Joseph is satisfied with you, you may pass. If it is all right with him, it is all right with me. Then if Joseph shall say to a man, or if brother Brigham say to a man, I forgive you your sins, ‘Whosoever sins ye remit they are remitted unto them;’ if you who have suffered and felt the weight of transgression—if you have generosity enough to forgive the sinner, I will forgive him: you cannot have more generosity than I have. I have given you power to forgive sins, and when the Lord gives a gift, he does not take it back again.”
- Apostle Orson Hyde, Journal of Discourses, v. 6, p. 154
