The last words of the verse describe the character in which the Son of God is expected by Christians to appear--Jesus, our deliverer[4] from the wrath to come (τῆς ὀργῆς τῆς ἐρχομένης). There is, then, according to apostolic teaching, a coming wrath--a wrath impending over the world, and actually on its way towards it. It is called the wrath to come, in distinction from anything of the same nature of which we have experience here. We all know the penal consequences which sin brings in its train even in this world. Remorse, unavailing sorrow, shame, fear, the sight of injury which we have done to those we love and which we cannot undo, incapacity for service,--all these are part and parcel of the fruit which sin bears. But they are not the wrath to come. They do not exhaust the judgment of God upon evil. Instead of discrediting it, they bear witness to it; they are, so to speak, its forerunners; the lurid clouds that appear here and there in the sky, but are finally lost in the dense mass of the thunderstorm. When the Apostle preached the gospel, he preached the wrath to come; without it, there would have been a missing link in the circle of Christian ideas. "I am not ashamed of the gospel of Christ," he says. Why? Because in it the righteousness of God is revealed, a righteousness which is God's gift and acceptable in God's sight. But why is such a revelation of righteousness necessary? Because the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men. The gospel is a revelation made to the world in view of a given situation, and the most prominent and threatening element in that situation is the impending wrath of God. The apostles do not prove it; they declare it. The proof of it is left to conscience, and to the Spirit of God reinforcing and quickening conscience; if anything can be added to this, it is the gospel itself; for if there were no such thing as the wrath of God, the gospel would be gratuitous. We may, if we please, evade the truth; we may pick and choose for ourselves among the elements of New Testament teaching, and reject all that is distasteful; we may take our stand upon pride, and decline to be threatened even by God; but we cannot be honest, and at the same time deny that Christ and His apostles warn us of wrath to come.
