The First Letter to the Thessalonians contains no references to the Name of the LORD.
The Second Letter to the Thessalonians has a portion in it (Chapter 2) where Paul describes what will happen before the LORD's coming from Heaven into the world again. It is good to read it and remember (I will post it after #312).
312. Second Letter to the Thessalonians 1:11-12 To this end, we always pray for you, that our God may make you worthy of His calling and powerfully bring to fulfillment every good purpose and every effort of faith, that the Name of our LORD Jesus may be glorified in you, and you in Him, in accord with the grace of our God and LORD Jesus Christ.
Chapter 2 We ask you brothers, with regard to the coming of our LORD Jesus Christ and our assembling with Him, not to be shaken out of your minds suddenly, or to be alarmed either by a "spirit," or by an oral statement, or by a letter allegedly from us to the effect that the day of the LORD is at hand. Let no one deceive you in any way. For unless the apostasy comes first and the lawless one is revealed, the one doomed to perdition, who opposes and exalts himself above every so-called god and object of worship, so as to seat himself in the temple of God, claiming that he is a god- do you not recall that while I was still with you I told you these things? And now you know what is restraining, that he may be revealed in his time. For the mystery of lawlessness is already at work. But the one who restrains is to do so only for the present, until he is removed from the scene. And then the lawless one will be revealed, whom the LORD [Jesus] will kill with the breath of His Mouth and render powerless by the manifestation of His coming, the one (antichrist) whose coming springs from the power of satan in every mighty deed and in signs and wonders that lie, and in every wicked deceit for those who are perishing because they have not accepted the love of truth so that they may be saved. Therefore, God is sending them a deceiving power so that they may believe the lie, that all who have not believed the truth but have approved wrongdoing may be condemned.
But we ought to give thanks to God for you always, brothers loved by the LORD, because God chose you as the firstfruits for salvation through sanctification by the Spirit and belief in truth. To this end He has [also] called you through the Gospel to possess the glory of our LORD Jesus Christ. Therefore, brothers, stand firm and hold fast to the traditions that you were taught, either by an oral statement or by a letter of ours.
May our LORD Jesus Christ Himself and God our Father, who has loved us and given us everlasting encouragement and good hope through His grace, encourage your hearts and strengthen them in every good deed and word.
