3 Do not let anyone 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, 4 who opposes and who exalts himself over every so-called god or object of worship, so that he sits down in the temple of God, proclaiming that he himself is God.
5 Do you not remember that whileb we were still with you, we were saying these things to you? 6 And you know that which restrains him now, so that he will be revealed in his own time. 7 For the mystery of lawlessness is at work already; only the one who now restrainsc will do so until he is out of the way,b 8 and then the lawless one will be revealed, whom the Lord Jesus will slay with the breath of his mouth, and wipe out by the appearance of his coming, 9 whose coming is in accordance with the working of Satan, with all power and signs and lying wonders, 10 and with every unrighteous deception against those who are perishing, in place of which they did not accept the love of the truth, so that they would be saved.
