New Heart English Bible
1Now, brothers, concerning the coming of our Lord Jesus Christ, and our gathering together to him, we ask you 2not to be quickly shaken in your mind, nor yet be troubled, either by spirit, or by word, or by letter as from us, saying that the day of the Lord had come. 3Let no one deceive you in any way. For it will not be, unless the rebellion comes first, and the man of lawlessness is revealed, the son of destruction, 4he who opposes and exalts himself against all that is called God or that is worshiped; so that he sits in the temple of God, setting himself up as God. 5Do you not remember that, when I was still with you, I told you these things? 6Now you know what is restraining him, to the end that he may be revealed in his own season. 7For the mystery of lawlessness already works. Only there is one who restrains now, until he is taken out of the way. 8Then the lawless one will be revealed, whom the Lord Jesus will kill with the breath of his mouth, and destroy by the manifestation of his coming; 9even he whose coming is according to the working of Satan with all power and signs and lying wonders, 10and with all deception of wickedness for those who are being lost, because they did not receive the love of the truth, that they might be saved. 11And because of this, God sends them a strong delusion, that they should believe the lie, 12in order that all might be judged who did not believe the truth, but had pleasure in unrighteousness.
13But we are bound to always give thanks to God for you, brothers loved by the Lord, because God chose you from the beginning for salvation through sanctification of the Spirit and belief in the truth; 14to which he called you through our Good News, for the obtaining of the glory of our Lord Jesus Christ. 15So then, brothers, stand firm, and hold the traditions which you were taught by us, whether by word, or by letter.
