We have some funny ideas about judging. Many of us think that we are not allowed to make any sort of judgment about what eternal reward someone will gain. But the scriptures state
In D&C 42:45 Thou shalt live together in love, insomuch that thou shalt weep for the loss of them that die, and more especially for those that have not hope of a glorious resurrection.
How can we obey this if we believe we are not allowed to decide who has a hope of a glorious resurrection? We cannot.
Why would the Lord give us a commandment that requires that we disobey him? He does not. There is no commandment that we pretend his plain words about his judgment will not all come to pass exactly as he has spoken. Quite to the contrary, we are required to have absolute faith in them. Part of which is simply accepting them.
D&C 63:17 Wherefore, I, the Lord, have said that the fearful, and the unbelieving, and all liars, and whosoever loveth and maketh a lie, and the whoremonger, and the sorcerer, shall have their part in that lake which burneth with fire and brimstone, which is the second death.
Like Amulek, we have no right to deny his word. That is not taking judgment from God, but leaving judgment in God’s hand.
Alma 11:36 Now Amulek saith again unto him: Behold thou hast lied, for thou sayest that I spake as though I had authority to command God because I said he shall not save his people in their sins.
37 And I say unto you again that he cannot save them in their sins; for I cannot deny his word, and he hath said that no unclean thing can inherit the kingdom of heaven; therefore, how can ye be saved, except ye inherit the kingdom of heaven? Therefore, ye cannot be saved in your sins.
