14 And death and hell were cast into the lake of fire. This is the second death.
This is a description of what follows the great white throne judgment. All the wicked dead shall be brought to life again and be judged according to their works by the Lord who sits upon the Throne. According to the previous verse, Revelation 20:13, “the sea gave up the dead which were in it; and death and hell delivered up the dead which were in them: and they were judged every man according to their works.” The mention of “the sea” giving up its dead makes it clear that regardless of how far a body has disintegrated, it will nevertheless be resurrected for this judgment. The physical bodies of the unsaved will be joined with their souls; then they will be cast into “the lake of fire”!>
The phrase “lake of fire” occurs only in Revelation, and that for a total of five times (19:20; 20:10, 14, 15; 21:8). In our text, the casting of the wicked dead into the lake of fire is referred to as “the second death”. It does not denote, as some say, annihilation or complete destruction of a person. According to their teaching, the soul and body of the wicked will be completely destroyed such that they will not suffer the eternal torment in hell or the lake of fire. That teaching of annihilation is unscriptural.
The lake of fire is the place where the wicked will suffer eternally the torments of hell. It is the place in which the wicked spend eternity in torment. John the Baptizer referred to hell as “unquenchable fire” (Matthew 3:12; Luke 3:17). Jesus referred to hell as “everlasting fire” (Matthew 18:8), and “everlasting punishment” (Matthew 25:46). He also described hell as “the fire that never shall be quenched: where their worm dieth not, and the fire is not quenched” (Mark 9:43b-44; cf. 9:46, 48).
This is the place where Satan, the Antichrist and the false prophet will also be cast into forever. Revelation 20:10 says, “And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet are, and shall be tormented day and night for ever and ever.” The epistle of Jude also testifies to the eternality of the hellfire, which is reserved for the wicked. Hell’s torment is referred to by Jude as “suffering the vengeance of eternal fire” (Jude 1:7).
Those who repent from their sin and trust in Christ do not have to fear the eternal hell. In Revelation 20:6, it is said concerning the believers that “on such the second death hath no power”.
