1Now concerning the coming of our Lord Jesus Christ and our being gathered together to him, we ask you, brothers, 2not to be quickly shaken in mind or alarmed, either by a spirit or a spoken word, or a letter seeming to be from us, to the effect that the day of the Lord has come. 3 Let 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 against 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 is restraining him now so that he may be revealed in his time. 7For the mystery of lawlessness is already at work. Only he who now restrains it will do so until he is out of the way. 8And then the lawless one will be revealed, whom the Lord Jesus will kill with the breath of his mouth and bring to nothing by the appearance of his coming. 9The coming of the lawless one is by the activity of Satan with all power and false signs and wonders, 10and with all wicked deception for those who are perishing, because they refused to love the truth and so be saved. 11Therefore God sends them a strong delusion, so that they may believe what is false, 12in order that all may be condemned who did not believe the truth but had pleasure in unrighteousness.
