Eternal Punishment
Not only is the future judgment of unbelievers irreversible, but their punishment is eternal. Annihilationism attempts to refute this, but the biblical evidence is staggering. It contradicts both OT and NT references to the "unending" or "unquenchable" fire. Jesus borrows the imagery of
Isa 66:24: "their worm does not die, and the fire is not quenched."
Other words are used to reinforce this too:
"Everlasting" "eternal" "forever"
all applied to nouns designating the future state of the wicked: fire or burning (
Isa 33:14,
Jer 17:4, Mt 18:8, 25:41,
Jude 7).
