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 1 apostasy comes first [unless the predicted great 1 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), 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. 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 3 he who restrains is taken out of the way. 8 And then the lawless one (the antichrist) will be revealed and the Lord Jesus will slay him with the breath of His mouth and bring him to an end by His appearing at His coming. 9 The coming [of the lawless one, the antichrist] is through the activity and working of Satan and will be attended by great power and with all sorts of [pretended] miracles and signs and delusive marvels--[all of them] lying wonders-- 10 And by unlimited seduction to evil and with all wicked deception for those who are perishing (going to perdition) because they did not welcome the Truth but refused to love it that they might be saved. 11 Therefore God sends upon them a misleading influence, a working of error and a strong delusion to make them believe what is false, 12 In order that all may be judged and condemned who did not believe in [who refused to adhere to, trust in, and rely on] the Truth, but [instead] took pleasure in unrighteousness.
13 But we, brethren beloved by the Lord, ought and are obligated [as those who are in debt] to give thanks always to God for you, because God chose you from the beginning 4 as His firstfruits (first converts) for salvation through the sanctifying work of the [Holy] Spirit and [your] belief in (adherence to, trust in, and reliance on) the Truth. 14 [It was] to this end that He called you through our Gospel, so that you may obtain and share in the glory of our Lord Jesus Christ (the Messiah). 15 So then, brethren, stand firm and hold fast to the traditions and instructions which you were taught by us, whether by our word of mouth or by letter.
16 Now may our Lord Jesus Christ Himself and God our Father, Who loved us and gave us everlasting consolation and encouragement and well-founded hope through [His] grace (unmerited favor), 17 Comfort and encourage your hearts and strengthen them [make them steadfast and keep them unswerving] in every good work and word.
