2 Thessalonians 2:1-5 New Revised Standard Version, Anglicised (NRSVA)
The Man of Lawlessness
2 As to the coming of our Lord Jesus Christ and our being gathered together to him, we beg you, brothers and sisters,[a] 2 not to be quickly shaken in mind or alarmed, either by spirit or by word or by letter, as though from us, to the effect that the day of the Lord is already here. 3 Let no one deceive you in any way; for that day will not come unless the rebellion comes first and the lawless one[b] is revealed, the one destined for destruction.[c] 4 He opposes and exalts himself above every so-called god or object of worship, so that he takes his seat in the temple of God, declaring himself to be God. 5 Do you not remember that I told you these things when I was still with you?
2 Thessalonians 2:13-17 New Revised Standard Version, Anglicised (NRSVA)
Chosen for Salvation
13 But we must always give thanks to God for you, brothers and sisters[a] beloved by the Lord, because God chose you as the first fruits[b] for salvation through sanctification by the Spirit and through belief in the truth. 14 For this purpose he called you through our proclamation of the good news,[c] so that you may obtain the glory of our Lord Jesus Christ. 15 So then, brothers and sisters,[d] stand firm and hold fast to the traditions that you were taught by us, either by word of mouth or by our letter.
16 Now may our Lord Jesus Christ himself and God our Father, who loved us and through grace gave us eternal comfort and good hope, 17 comfort your hearts and strengthen them in every good work and word.
