“Hell Which Hath No End”

"Hell is that portion of the postmortal spirit world wherein the wicked suffer and repent and reconsider. It is also known as 'outer darkness,' a place of 'weeping, and wailing, and gnashing of teeth,' this because of the wickedness of those who have suffered themselves to be led captive by Lucifer (see Alma 40:13-14). The 'lake of fire and brimstone,' whose flames ascend up forever and ever, is descriptive of the torment of conscience in this place (see Teachings, pp. 310-11, 357). Both paradise and hell have an end in the Resurrection. Hell is the gateway to the telestial kingdom. It is endless in the sense that those who experience it are subject to the punishment of God, whose name is Endless (D&C 19:10-12)." (McConkie and Millet, Doctrinal Commentary on the Book of Mormon, vol. 1, p. 108)
