Perhaps you're missing the point. The Apostle Paul was simply encouraging the Thessalonian believers to not grieve over the one's who have died as one who has no hope. Paul reminds them they have a hope because just as Jesus died and rose again, God through Jesus will bring those who died with Him too.
Saul encourages the Jews and Jewish Christians in all his letters to believers in the various churches in Asia Minor and Italy. A good example is Romans 10:9-10. That's all it is. Just Saul writing to Jewish Christians at Rome and encouraging them that they had believed in their hearts and confessed with their mouths that God raised Jesus from the dead/grave is simple evidence they are saved. It is NOT a formula for salvation.
But I know what Saul was writing in the Thessalonian letters. And I have not said anything contrary to what is written.
Paul simply assures them that our Lord will resurrect the dead at His coming and those who are alive will be caught up with Him in the clouds while in the air, and so we will always be with the Lord. This was for their understanding and reassurance. Nowhere does Paul express we will be with the Lord forever in the air. He simply said will meet the Lord in the clouds while He is in the air at His coming. He was not using dramatic similitude language that prophets use such as Zechariah or John in Revelation, for that was not the purpose. So please don't expect what you're expecting. Paul was not wrong. And he was not lying.
God Bless
The way certain individuals interpret Saul's words about meeting Christ in the air as proof of a rapture is false. There is nothing in Scripture of a "rapture."
The way Jesus ascended is the same way He's coming back. And it's not to meet anyone in the air and to remain in the air.
16 For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first:
17 Then we which are alive and remain shall be
caught up together with them in the clouds,
to meet the Lord in the air: and so shall we ever be with the Lord. 1 Thessalonians 4:16–17.
Believers do not meet Christ in the air. They meet Christ when His foot touches down upon Mount Olives. The way He went up is the same way He's coming back.
This is what's going to happen when Christ returns:
11 And I saw heaven opened, and behold a white horse; and he that sat upon him was called Faithful and True, and in righteousness he doth judge and make war.
Jesus returns with His armies, and He engages in battle alongside Israel against her enemies.
12 His eyes were as a flame of fire, and on his head were many crowns; and he had a name written, that no man knew, but he himself.
13 And he was clothed with a vesture dipped in blood: and his name is called The Word of God.
14 And the armies which were in heaven followed him upon white horses, clothed in fine linen, white and clean.
His armies follow Him down to Mount Olives where He is on the ground and engaged in battle. It's a bloodbath against the Gentiles who are fighting Israel and the battle is so fierce that His clothing becomes stained with the blood of His enemies.
15 And out of his mouth goeth a sharp sword, that with it he should smite the nations: and he shall rule them with a rod of iron: and he treadeth the winepress of the fierceness and wrath of Almighty God.
16 And he hath on his vesture and on his thigh a name written, KING OF KINGS, AND LORD OF LORDS.
Revelation 19:11–16.
This is an event that begins in the heavens and concludes on the ground. He doesn't meet anyone "in the air."
The way He went up is the same way He's coming down, except this time He's accompanied by His saints and His armies and He is personally involved in directly destroying His enemies the Gentiles.
