1 Now, brothers, concerning the coming of our Lord Jesus Christ and our gathering together to him, we ask you 2 not to be quickly shaken in your mind or troubled, either by spirit or by word or by letter as if from us, saying that the day of Christ has already come. 3 Let no one deceive you in any way. For it will not be unless the rebellion comes first, and the man of sin is revealed, the son of destruction. 4 He opposes and exalts himself against all that is called God or that is worshiped, so that he sits as God in the temple of God, setting himself up as God.
