The Importance of an Endless Hell

"Unholy as we are, we are disqualified from saying that infinite holiness doesn't demand everlasting punishment. By denying the endlessness of Hell, we minimise Christ's work on the cross. Why? Because we lower the stakes of redemption. If Christ's crucifixion and resurrection didn't deliver us from an eternal Hell, his work on the cross is less heroic, less potent, less consequential, and thus less deserving of our worship and praise. As theologian William G. T. Sheds put it, "The doctrine of Christ's vicarious atonement logically stands or falls with that of eternal punishment."

"Many books deny Hell. Some embrace universalism, the belief that all people will ultimately be saved. Some consider Hell to be the invention of wild-eyed prophets obsessed with wrath. They argue that Christians should take the higher road of Christ's love. But this perspective overlooks a conspicuous reality: In the Bible, Jesus says more than anyone else about Hell (Matthew 10:28; 13:40-43; Mark 9:43-44)."
