Thessalonians in English translation
For that day will not arrive, unless the apostasy comes first and the man of lawlessness is revealed, the son of perdition,  who opposes and exalts himself against every so-called god or object of worship, so that he takes his seat in the temple of God, declaring himself to be God.  Do you not remember that I told you these things when I was still with you?  And now you know what restrains him, so that he will be revealed at his own time.  For the mystery of lawlessness is already at work, only until the one who restrains now will have disappeared.  And then the lawless one will be revealed, he whom the Lord Jesus will kill with the breath of his mouth and destroy by the manifestation of his coming,  the one whose coming takes place by virtue of the work of Satan with all power and false signs and wonders  and with all sinful deceit, for those who perish, because they did not accept the love of the truth so as to be saved.  And therefore God sends them a power that works delusion, so that they believe what is false,  in order that all may be judged who did not believe the truth but had pleasure in sinfulness.
