1Now concerning the coming of our Lord Jesus Christ and our gathering together to him, we beg you, brethren, 2not to be quickly shaken in mind or excited, either by spirit or by word, or by letter as if from us, to the effect that the day of the Lord has come. 3Let no one deceive you in any way; for that day will not come, unless the rebellion comes first, and the man of lawlessness is revealed, the son of destruction, 4who opposes and exalts himself above every so-called god or object of worship, so that he takes his seat in the temple of God, proclaiming himself to be God. 5Do you not remember that when I was still with you I told you these things? 6And you know what restrains him now, so that in his time he may be revealed. 7For the mystery of lawlessness is already at work; only he who now restrains will do so until he is taken out of the way. 8And then the lawless one will be revealed, whom the Lord Jesus will slay with the breath of his mouth and destroy by the splendor of his coming. 9The coming of the lawless one by the activity of Satan will be with all power and with pretended signs and wonders, 10and with all the deception of wickedness for those who are to perish, because they refused to love the truth and so be saved. 11For this reason God sends upon them a strong delusion so that they will believe what is false, 12so that all may be condemned who did not believe the truth but had pleasure in wickedness. 13But we are bound to give thanks to God always for you, brethren beloved by the Lord, because God chose you from the beginning to be saved, through sanctification by the Spirit and belief in the truth. 14He called you to this through our gospel, that you may share in the glory of our Lord Jesus Christ. 15So then, brethren, stand firm and hold to the traditions which you were taught, whether by word of mouth or by letter from us. 16Now may our Lord Jesus Christ himself and God our Father, who loved us and gave us eternal comfort and good hope by grace, 17comfort and strengthen your hearts in every good work and word.
