1 Thessalonians is clarified in 2 Thessalonians, especially chapter 2. Never read them separately.
3 Let no one in any way deceive you, for it will not come unless the apostasy comes first, and the man of lawlessness is revealed, the son of destruction, 4 who opposes and exalts himself above every so-called god or object of worship, so that he takes his seat in the temple of God, displaying himself as being God.
Acts 24:14&15 14 But this I admit to you, that according to the Way which they call a sect I do serve the God of our fathers, believing everything that is in accordance with the Law and that is written in the Prophets; 15 having a hope in God, which these men cherish themselves, that there shall certainly be a resurrection of both the righteous and the wicked.
“both the righteous and the wicked.”
John 5
24 “Truly, truly, I say to you, he who hears My word, and believes Him who sent Me, has eternal life, and does not come into judgment, but has passed out of death into life.
Two Resurrections
25 Truly, truly, I say to you, an hour is coming and now is, when the dead will hear the voice of the Son of God, and those who hear will live. 26 For just as the Father has life in Himself, even so He gave to the Son also to have life in Himself; 27 and He gave Him authority to execute judgment, because He is the Son of Man. 28 Do not marvel at this; for an hour is coming, in which all who are in the tombs will hear His voice, 29 and will come forth; those who did the good deeds to a resurrection of life, those who committed the evil deeds to a resurrection of judgment.
Jesus is speaking of the resurrection of all who died, righteous and unrighteous. It is inclusive. In Revelation, the first resurrection at His return includes only those who have died in faith, having been sealed by God.
Revelation 20
4 Then I saw thrones, and they sat on them, and judgment was given to them. And I saw the souls of those who had been beheaded because of [b]their testimony of Jesus and because of the word of God, and those who had not worshiped the beast or his image, and had not received the mark on their forehead and on their hand; and they came to life and reigned with Christ for a thousand years. 5 The rest of the dead did not come to life until the thousand years were completed. This is the first resurrection. 6 Blessed and holy is the one who has a part in the first resurrection; over these the second death has no power, but they will be priests of God and of Christ and will reign with Him for a thousand years.
I study book by book, cover to cover. Then I use a concordance. I read the whole chapter. If it is still discordant, I read the whole book.
2 Thess 2:1 Now, brothers, concerning the coming of our Lord Jesus Christ, and our gathering together to him, we ask you not to be quickly shaken in your mind, nor yet be troubled, either by spirit, or by word, or by letter as from us, saying that the day of Christ had come.Let no one deceive you in any way. For it will not be, unless 1) the departure comes first, and 2) the man of sin is revealed, the son of destruction, he who opposes and exalts himself against all that is called God or that is worshiped; so that he sits as God in the temple of God, setting himself up as God. Don't you remember that, when I was still with you, I told you these things? Now you know what is restraining him, to the end that he may be revealed in his own season.
For the mystery of lawlessness already works. Only there is one who restrains now, until he is taken out of the way.{reference 1 above] Then the lawless one will be revealed[Reference 2 above], whom the Lord will kill with the breath of his mouth, and destroy by the manifestation of his coming; even he whose coming is according to the working of Satan with all power and signs and lying wonders, 1and with all deception of wickedness for those who are being lost, because they didn't receive the love of the truth, that they might be saved. Because of this, God sends them a working of error, that they should believe a lie; that they all might be judged who didn't believe the truth, but had pleasure in unrighteousness.
The departure comes before the revealing and then after the revealing the strong delusion, then the final wraths are poured out upon the unbelievers who would rather believe the lie than be saved by faith in Christ.
“Jesus is speaking of the resurrection of all who died, righteous and unrighteous. It is inclusive.”
Jesus clearly refers to them in two separate terms, “the resurrection of the righteous” and the “resurrection of the wicked”. Those aren’t inclusive terms. Revelation describes two resurrections as well, in similar terms, one resurrection where believers are glorified, and another resurrection where people face judgement and death. They are both in agreement that there are two resurrections, and in agreement as to the nature of the resurrections, so why disagree with them?
Also, if you Jesus is only referring to the second resurrection here, take note that he says:
“those who did the good deeds to a resurrection of life”
Does this mean you believe that some people in the second resurrection will be judged righteous based on their “good deeds”, their works, and will be given life?
“In Revelation, the first resurrection at His return includes only those who have died in faith, having been sealed by God.”
This includes ALL who are saved. There is no special resurrection for some special subset of the church spoken of in the Bible. Instead we have clear verses that tell us all who are “in Christ” will rise together.
Also, if you believe that the faithful will be part of the second resurrection, then do you also believe the faithful will be judged on their works? Or that they will be subject to the Second Death? (Rev. 20:6, Rev. 20:12-14)
