5 Don’t you remember that when I was with you I used to tell you these things?
6 And now you know what is holding him back, so that he may be revealed at the proper time.
7 For the secret power of lawlessness is already at work; but the one who now holds it back will continue to do so till he is taken out of the way.
8 And then the lawless one will be revealed, whom the Lord Jesus will overthrow with the breath of his mouth and destroy by the splendor of his coming.
9 The coming of the lawless one will be in accordance with how Satan works. He will use all sorts of displays of power through signs and wonders that serve the lie,
10 and all the ways that wickedness deceives those who are perishing. They perish because they refused to love the truth and so be saved.
11 For this reason God sends them a powerful delusion so that they will believe the lie
12 and so that all will be condemned who have not believed the truth but have delighted in wickedness.

Stand Firm

13 But we ought always to thank God for you, brothers and sisters loved by the Lord, because God chose you as firstfruitsa to be saved through the sanctifying work of the Spirit and through belief in the truth.
14 He called you to this through our gospel, that you might share in the glory of our Lord Jesus Christ.
15 So then, brothers and sisters, stand firm and hold fast to the teachingsb we passed on to you, whether by word of mouth or by letter.
