“In the prophecy this warning of the judgment, with its connected messages, is followed by the coming of the Son of man in the clouds of heaven. The proclamation of the judgment is an announcement of Christ’s second coming as at hand. And this proclamation is called the everlasting gospel. Thus the preaching of Christ’s second coming, the announcement of its nearness, is shown to be an essential part of the gospel message.”
