“The phrase ‘lake of fire and brimstone’ … is generally used to describe either the place that awaits the unrepentant individual after the Judgment or the mental anguish associated with sin. … In reference to mental anguish, 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. The torment of disappointment in the mind of man is as exquisite as a lake burning with fire and brimstone’” (Book of Mormon Student Manual [2009], 127).
