What does the Bible say about the eternal suffering of the wicked in hell?

The Scriptures convey the severe reality of eternal suffering for the wicked. Isaiah 66:24 states, 'For their worm shall not die, neither shall their fire be quenched.' This emphasizes the unending nature of their torment, paralleling the New Testament language found in Mark 9:48. The imagery of an eternal fire and a conscience that continually gnaws at the soul demonstrates that hell is not a temporary state, but a perpetual existence of anguish where the punishment matches the gravity of sin against an infinite God.
