15 For this we declare to you by a word from the Lord, [1] that we who are alive, who are left until the coming of the Lord, will not precede those who have fallen asleep. 16 For the Lord himself will descend from heaven with a cry of command, with the voice of an archangel, and with the sound of the trumpet of God. And the dead in Christ will rise first. 17 Then we who are alive, who are left, will be caught up together with them in the clouds to meet the Lord in the air, and so we will always be with the Lord.

10 But the day of the Lord will come like a thief, and then the heavens will pass away with a roar, and the heavenly bodies [2] will be burned up and dissolved, and the earth and the works that are done on it will be exposed. [3]

The Judgment at Christ's Coming

5 This is evidence of the righteous judgment of God, that you may be considered worthy of the kingdom of God, for which you are also suffering— 6 since indeed God considers it just to repay with affliction those who afflict you, 7 and to grant relief to you who are afflicted as well as to us, when the Lord Jesus is revealed from heaven with his mighty angels 8 in flaming fire, inflicting vengeance on those who do not know God and on those who do not obey the gospel of our Lord Jesus. 9 They will suffer the punishment of eternal destruction, away from [4] the presence of the Lord and from the glory of his might, 10 when he comes on that day to be glorified in his saints, and to be marveled at among all who have believed, because our testimony to you was believed.
