1 BUT RELATIVE to the coming of our Lord Jesus Christ (the Messiah) and our gathering together to [meet] Him, we beg you, brethren,
2 Not to allow your minds to be quickly unsettled or disturbed or kept excited or alarmed, whether it be by some [pretended] revelation of [the] Spirit or by word or by letter [alleged to be] from us, to the effect that the day of the Lord has [already] arrived and is here.
3 Let no one deceive or beguile you in any way, for that day will not come except the apostasy comes first [unless the predicted great falling away of those who have professed to be Christians has come], and the man of lawlessness (sin) is revealed, who is the son of doom (of perdition), [Dan. 7:25; 8:25; I Tim. 4:1.]
4 Who opposes and exalts himself so proudly and insolently against and over all that is called God or that is worshiped, [even to his actually] taking his seat in the temple of God, proclaiming that he himself is God. [Ezek. 28:2; Dan. 11:36, 37.]
5 Do you not recollect that when I was still with you, I told you these things?
6 And now you know what is restraining him [from being revealed at this time]; it is so that he may be manifested (revealed) in his own [appointed] time.
7 For the mystery of lawlessness (that hidden principle of rebellion against constituted authority) is already at work in the world, [but it is] restrained only until he who restrains is taken out of the way.
