Men “Are Their Own Judges”
Alma 41:4–7
4 And if their works are evil they shall be restored unto them for evil. Therefore, all things shall be restored to their proper order, every thing to its natural frame—mortality raised to immortality, corruption to incorruption—raised to endless happiness to inherit the kingdom of God, or to endless misery to inherit the kingdom of the devil, the one on one hand, the other on the other—
5 The one raised to happiness according to his desires of happiness, or good according to his desires of good; and the other to evil according to his desires of evil; for as he has desired to do evil all the day long even so shall he have his reward of evil when the night cometh.
6 And so it is on the other hand. If he hath repented of his sins, and desired righteousness until the end of his days, even so he shall be rewarded unto righteousness.
7 These are they that are redeemed of the Lord; yea, these are they that are taken out, that are delivered from that endless night of darkness; and thus they stand or fall; for behold, they are their own judges, whether to do good or do evil.
The Prophet Joseph Smith said:
“A man is his own tormentor and his own condemner. Hence the saying, They shall go into the lake that burns with fire and brimstone [see Revelation 21:8]. The torment of disappointment in the mind of man is as exquisite as a lake burning with fire and brimstone. I say, so is the torment of man.”
