1 Now we ask you, brothers, regarding the coming of our Lord Jesus, the Messiah, and our gathering together to him, 2 not to be so quickly upset or alarmed when someone claims that we said, either by some spirit, conversation, or letter that the Day of the Lord has already come. 3 Do not let anyone deceive you in any way, for it will not come unless the rebellion takes place first and the man of sin, who is destined for destruction, is revealed. 4 He opposes and exalts himself above every so-called god and object of worship. As a result, he seats himself in the sanctuary of God and himself declares that he is God.
5 Don't you remember that I repeatedly told you about these things when I was still with you? 6 You know what it is that is now holding him back, so that he will be revealed when his time comes. 7 For the secret of this lawlessness is already at work, but only until the person now holding it back gets out of the way. 8 Then the lawless one will be revealed, whom the Lord will destroy with the breath of his mouth, rendering him powerless by the manifestation of his coming. 9 The coming of the lawless one will be accompanied by the power of Satan. He will use every kind of power, including miraculous signs, lying wonders, 10 and every type of evil to deceive those who are dying, those who refused to love the truth that would save them. 11 For this reason, God will send them a powerful delusion so that they will believe the lie. 12 Then all who have not believed the truth but have taken pleasure in unrighteousness will be condemned.
13 At all times we are obligated to thank God for you, brothers who are loved by the Lord, because God chose you to be the first fruits for salvation through sanctification by the Spirit and through faith in the truth. 14 With this purpose in mind, he called you through our proclamation of the gospel so that you would obtain the glory of our Lord Jesus, the Messiah. 15 So then, brothers, stand firm, and cling to the traditions that you were taught by us, either by word of mouth or by our letter.
