Yes. Daniel 7:13 is the Old Testament example of the coming of Christ that Thessalonians refers to. Strong's H6050 refers back to H6049 a "very large army". Remember Elisha opening the veil of the clouds and showing his armor-bearer the very large army God assembled for that day they would prevail? When we meet, it it be the clouds of people all taken up at once, good, bad, whatever. 7 billion of us at once.
Sorry, in this it is not "spirit" in Strong's Dictionary of his Concordance, nor is it "spirit" anywhere in the Authorized Version. It is never used in the figurative sense. In this, your claim is absolutely wrong:
The Strong's word for "spirit" is H7307 which of course also means "air". For a human to meet anyone in the "air" they must be in the spirit. When Thessalonians says anyone is going to meet anyone else in the air, that means that they must have moved into the Strong's H7307, into the spirit.
This is entirely presuming that the Seventh Trump of Rev. 11:15 has any connection with the trumpet of this context. Even the contexts are not the same. I just don't believe your hypothesis here can be given any serious recognition, because it is eisegesis, not exegesis, and even then forced. The correct frame of mind is given in the next chapter, verses 9 and 10: "For God hath not appointed us to wrath, but to obtain salvation by our Lord Jesus Christ, Who died for us, that, whether we wake or sleep, we should live together with him." Not His tribulational wrath, because of the imputation of Christ's righteousness, and certainly not of Satan's. Furthermore, I believe the salvation mentioned here is not only the cetification of it by entrance into His Kingdom through justification by faith, but the realization of it by the saving through joining Him in the clouds in the new spiritual body. Anything else than that is not much of a salvation, is it?
Oh no! He wants the Tribulation to be a time of great glory for Him and for those that love Him. Remember what happened to the three Hebrews in Nebuchadnezzar's fiery furnace, a fire seven times hotter to instantly kill anyone, and Jesus stood with them and not a hair was singed and no smell of smoke accompanied the three Hebrews when they emerged. All the prophets wanted to live in our time. Why? To run away? No! To stand against Satan. God's people have nothing to fear from the Tribulation, it's a time of glory for them.
