Now concerning the coming of our Lord Jesus Christ and our being gathered to him: We ask you, brothers and sisters, not to be easily upset or troubled, either by a prophecy or by a message or by a letter supposedly from us, alleging that the day of the Lord has come. Don’t let anyone deceive you in any way. For that day will not come unless the apostasy comes first and the man of lawlessness is revealed, the man doomed to destruction. He opposes and exalts himself above every so-called god or object of worship, so that he sits in God’s temple, proclaiming that he himself is God.
Don’t you remember that when I was still with you I used to tell you about this? And you know what currently restrains him, so that he will be revealed in his time. For the mystery of lawlessness is already at work, but the one now restraining will do so until he is out of the way
