1 Thessalonians 1:10

"And to wait," he says, "for His Son from heaven, whom He raised from the dead, even Jesus, which delivereth us from the wrath to come." "And to wait," he says, "for His Son from heaven"; Him that was crucified, Him that was buried; to wait for Him from heaven. And how "from heaven"? "Whom He raised from the dead." You see all things at the same time; both the Resurrection, and the Ascension, and the second Coming, the Judgment, the retribution of the just, the punishment of the wicked. "Jesus," he says, "which delivereth us from the wrath to come." This is at once comfort, and exhortation, and encouragement. For if He raised Him from the dead, and He is in heaven, and thence will come, (and ye believed in Him; for if ye had not believed in Him, ye would not have suffered so much), this of itself is sufficient comfort. These shall suffer punishment, which he says in his second epistle, and you will have no small consolation.

And to "wait," he says, "for His Son from heaven." The terrible things are in hand, but the good things are in the future, when Christ shall come from heaven. See how much hope is required, in that He who was crucified has been raised, that He has been taken up into heaven, that He will come to judge the quick and the dead.

And this is a characteristic of the same method; because in the form of a narrative he taught them to await the Son of God. For the greatest consolation for those who grieve is that the One who suffered has risen and is in heaven, that He will come and deliver us who grieve from the coming wrath, that is, from punishment, as those who have truly pleased Him through faith and a blameless life. But those who cause us grief He will not spare. Since afflictions are overhead, while blessings are in the future, the apostle ascribes to them great faith, as those who await and firmly hope in what is to come.

Since those who serve Him deserve a reward, and because this is the case with the Thessalonians, it remains for them to expect a reward; so Paul says to them, "to wait for his Son," that is, God, descending from heaven. "Be like men who are waiting for their master to come home from the marriage feast" (Lk. 12:36). "Blessed are all those who wait for him" (Is. 30:18). These, however, are the men who girded their loins. We, however, are waiting for two things: first, for the resurrection, in order that we may clearly conform to Christ; hence Paul says: "whom he raised from the dead." "He who raised Christ Jesus from the dead will give life to your mortal bodies" (Rom. 8:11). "Who will change our lowly body to be like his glorious body" (Phil. 3:21). Secondly, we are waiting to be freed from the punishment which awaits the guilty. For we shall be freed by Christ from sin, the cause of punishment. So Paul says: "Jesus who delivers us from the wrath to come." "Hide us from the face of him who is seated on the throne, and from the wrath of the Lamb" (Rev. 6:16). No one can free us from this wrath but Christ: "Who warned you to flee from the wrath to come?" (Matt. 3:7).

Jesus, who has rescued us from the approaching wrath
that is the punishment of Gehenna.
