Not to argue your point as there is only ONE rapture for the church, but . . .
I did see your thread back then, but I disagree with it. Here's why. I believe verses 15-17 parallel Isaiah 49:10, which I believe is an "earthly MK" verse and passage. It is showing their end destination (after having been coming out of "the great tribulation" [2nd half of trib]).
I agree with what William Kelly says here, regarding the "a great multitude... of all the nations [Gentiles]" of Rev7:9 -
[quoting]
"Here we read that one of the elders talked about the Gentile crowd, and explained who they were to the prophet, as he evidently without this would have been at fault. If the elders mean the glorified saints, these Gentiles cannot. Most assuredly they are not all the saints, because the hundred and forty-four thousand of Israel we have seen expressly distinguished from them; and so are the Jewish remnant in Rev. 14. Who are they and what? They are a crowd of Gentiles to be preserved by God's gracious power in these last days. Not a word implies that here they were glorified; there is no reason to doubt that they were still in their natural bodies. If they are said to be "before the throne," this cannot overthrow the many proofs that they are alive on the earth. Thus the woman, for instance (in Rev. 12), is also described as seen in heaven; but this is only where the prophet saw her in the vision. Why are we necessarily to gather that these Gentiles belong to heaven? The seer saw them there, but whether "before the throne" means that they are actually in heaven is another question, to be decided by the evidence as a whole.
"In this case it is plain from other statements that they are not heavenly; and to it are weighty objections.
First of all they are definitely contra-distinguished from Israel, who clearly are on earth, and thus naturally this company would be on earth too, the one Jewish, and the other Gentile. Next they "come out of the great tribulation." Far from its being a general body in respect to all time, this proves that it is a future and peculiar though countless group; for it consists only of Gentiles preserved and blessed of God as coming out of "the great tribulation."
"In the millennial time there will be a great ingathering of the Gentiles;
but those before us [that is, those referred to in 7:9] precede that day. They are saints from among the Gentiles
at the great crisis, called to the knowledge of God by the preaching of the "gospel of the kingdom," or the "everlasting gospel," of which we hear respectively in the Gospel of Matthew [24:14, 26:13] and in the Revelation. The Lord Himself tells the disciples that "this gospel of the kingdom" shall be "preached in all the world for a witness unto all the nations" (or all the Gentiles); "and then shall the end come." Is not this the very time spoken of here? It is clearly not a general summary of what God is doing now, but a description of what is yet to be, specially just before the end, when "the great tribulation" bursts out. John saw the fruit of divine grace even then in this vast crowd from among the Gentiles. The details of the description fall in with and confirm this inference. But the unparalleled tribulation is to fall on the Jews, as we are also told. This is far wider, and not so severe."

I believe they are "resurrected" to stand again on the earth (not "raptured," which pertains SOLELY to "the Church which is His body" and only occurs ONCE).
