The concept of eternal punishment is indeed present in the Bible, particularly in the New Testament, where the duration and nature of punishment for the wicked is described in terms that emphasize its severity and perpetuity.

One of the clearest references to the eternal nature of punishment is found in the book of Revelation, where it speaks of the devil, the beast, and the false prophet being “tormented day and night forever and ever” (Revelation 20:10, ESV). Additionally, Revelation 14:11 describes the fate of those who worship the beast and its image, saying, “And the smoke of their torment goes up forever and ever, and they have no rest, day or night” (ESV).

Jesus Himself spoke of eternal punishment in contrast to eternal life. In Matthew 25:46, at the conclusion of the parable of the sheep and the goats, He states, “And these will go away into eternal punishment, but the righteous into eternal life” (ESV). The parallelism in this verse emphasizes the enduring nature of both destinies.

These passages, among others, have led to the traditional Christian understanding that hell is a place or state of eternal separation from God and eternal punishment for the unrighteous. This belief underscores the gravity of sin and the urgency of repentance, faith in Christ, and living a life in accordance with God’s will. It also highlights the infinite love and justice of God, who desires that no one should perish but that all should reach repentance (2 Peter 3:9).
