The doctrine of the dreadful destiny of the lost is an unpleasant shadow across biblical doctrine. So it is not very remarkable that the surveys of religious opinion, frequently reported in the press, will relate that of the same church people, who by strong majority believe in God, immortality, the divinity of Jesus and heaven, many dissent from a belief in hell. Yet that doctrine stands behind and enforces the need for the incarnation of the Son of God, His sinless life, and especially His substitutionary atonement and present ministry of intercession. It also sustains the common moral life of mankind and is indispensable to any strong apostolic fervor in Christian missions and evangelism.
