There are many cults today that deny the doctrine of the eternality of hell. Some of these groups (such as Jehovah’s Witnesses and Seventh Day Adventists) instead claim that God will merely annihilate those have not turned from their sins.

Hell is a place of “eternal destruction, away from the presence of the Lord” (2 Thes.1:9), “unquenchable fire” (Mat.3:12; Mark 9:43), a place of “utter darkness” (Jude 13) where there will be “weeping and gnashing of teeth (Luke 13:28).
