Eternal death, as the recompense for the wicked, stands in stark contrast to the hope of resurrection for the faithful. The Lake of Fire, described in Revelation, serves as the ultimate place of final punishment where mortal men like the Beast and False Prophet are utterly consumed by flames that devour all, as the elements melt with fervent heat and the earth itself is burned up. For Satan and the demons, being spirit beings, the torment in the Lake of Fire may endure for a longer, though still indeterminate, time before they expire, suffering the torture and excruciating pain of fervent heat with unstinting thoroughness, as God delivers the most painful and complete punishment they rightfully deserve. God's perfect judgment ensures that all sin and sinners, including the Adversary and his demons, are completely erased from existence, allowing only righteousness to dwell in the new heavens and new earth.

Eternal death is presented as the second death, God's just and merciful penalty for those who, after being given full opportunity to learn and understand the consequences of sin, choose to persist in rebellion against Him. This concept is framed as the ultimate wages of sin—not eternal life in conscious torment, but eternal sleep, a permanent cessation of existence. Herbert W. Armstrong's paraphrase of Paul is cited directly: "The wages of sin is death! Eternal death! Not eternal life in hell-fire, agony and misery!" This understanding reveals God's character as loving and merciful even in judgment, demonstrating that when He commands His people to love their enemies, He asks nothing of them that He is not willing to do Himself. Eternal death is distinguished from the first death, the physical death common to all humanity, which serves as a temporary, dreamless sleep—unlike Christ's own three-day rest in the tomb, human sleep may last longer, but time is not experienced during unconsciousness. The first death was built into human design by God for good purposes, partly to prevent immortal, unrepentant sinners from living forever in misery, as demonstrated by the corrupted long-lived generations before the Flood. God shortened the human lifespan afterward, illustrating the consequences of prolonged disobedience. The second death, eternal death, is tied inseparably to the destruction of sin itself. Death and sin are described as enemies—real enemies that God has permitted to exist for the ultimate testing and refinement of His people—but enemies destined for total destruction. Christ's own death and resurrection constituted the first and most decisive battle in the war against sin and death, since death no longer has dominion over Him. Believers, as fellow soldiers, participate in this ongoing conflict, anticipating further victories: an intermediate one at the first resurrection, ongoing struggles during the Millennium to purge sin from human nature, and a final battle after the Millennium when Satan is permanently imprisoned. The culmination of this struggle appears in the vision of the great white throne judgment, where the dead are judged according to their works, and Death and Hades themselves are cast into the lake of fire—identified explicitly as the second death. Those not found in the Book of Life share this fate. This is not depicted as a tragedy but as the final, necessary elimination of sin and death from creation, fulfilling God's purpose of eliminating suffering permanently. The promise that follows—no more death, sorrow, crying, or pain—represents the ultimate vindication of the Passover sacrifice, showing that eternal death exists within a redemptive framework: God's justice, His mercy in sparing the wicked from endless torment, and His ultimate victory over sin, death, and Satan through the sacrifice and reign of Jesus Christ.
