Very good, S.
Regarding the placement of the rapture in the seven years of tribulation and judgment, here is a brief summary.
The Savior determines that it is time for his return. He is the rider of the white horse in Rev. 6:2 as revealed in Rev. 19:11. He had previously gone forth conquering death (Rev. 5:6), and now he is going forth to conquer Lucifer and wickedness from the earth. That is, he is going to take dominion over the earth.
The first thing that Jesus does in taking dominion over the earth is to destroy Babylon, the economic system. This is a system whereby the people have personal profit by serving other gods. Babylon has dominated the earth since the time of Adam.
Under Jesus' coming economic system, as shown in Rev. 21, the saints serve the eternal God and their reward is eternal life. This transfer from Babylon to New Jerusalem is given in the fourth storyline that I call the fall of Babylon storyline as shown in the follow chiasmus:
a) Ch. 17, Babylon is judged and burned (Rev. 17:1, Rev. 17:16).
b) Ch. 18, The 3.5-year tribulation begins where fallen Babylon gives way to the rule of the wicked upon the earth (Rev. 18:2). In response to the wicked who have taken over the earth after the fall of Babylon comes the call of the Savior for his army to embark on an exodus (Rev. 18:4).
c) THE CHIASMUS CENTER,
Ch. 19, The saints of the exodus arrive at their destination, where they participate in the marriage (Rev. 19:1-8). It is here that the 144,000 (Rev. 7) become sealed as the Savior's army (Rev. 14:1), going forth to harvest the saints of God (Rev. 14:14-16) and destroy the beast and his false prophet in the winepress (Rev. 14:14-20, Rev. 19:19-21), ending the 3.5-year tribulation. After the victory over the beast (Rev. 15:2), the 3.5-year judgment begins (Rev. 11:3), where the Savior's army goes forth to judge the remaining population of the earth. This army is given prescribed guidelines whereby they are to judge (Rev. 16:2-7).
b) Ch. 20, And with the battle of Armageddon (Rev. 16:16), the 3.5-year judgment ends. It is here that the two witnesses, as well as the saints of God, are taken off the earth in a rapture (Rev. 11:11-12). And with the destruction of the wicked in Armageddon, and the saints being taken off the earth in a rapture, Satan is bound for a thousand years (Rev. 20:1-3). Then comes the first resurrection proper (Rev. 20:4-6) during the thousand years, followed by the release of satan after the thousand years are over (Rev. 20:7-9). Satan is then cast into hell with the beast and false prophet, and then comes the judgment of the spiritually dead.
a) Ch. 21, New Jerusalem, having with the eternal economy of God, descends to the earth.
S, as you can see, there is an exodus, harvest, and rapture, in that order, as shown in the fall of Babylon storyline.
