1Th 4:16 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:
1Th 4:17 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.
The dead and the living will be changed immediately--in the twinkling of an eye---the dead and the living saved!! The dead and living wicked are all dead with His coming. And remain so.
Rev 20:5 But the rest of the dead lived not again until the thousand years were finished. This is the first resurrection.
Those are not resurrected until after the 1000 years and their sentences are pronounced and they are thrown in hell.
4:16 is the first Resurrection of the righteous dead.
4:17 is the second Resurrection that takes place about 3 years later where all the ungodly(dead and alive) and all the righteous will be called on the day of judgment. The righteous will be forever with the Lord after judgment and the unrighteous will not.
2. This is the timeline. Satan is cast into the bottomless pit for about 3 years.
3 And cast him into the bottomless pit, and shut him up, and set a seal upon him, that he should deceive the nations no more, till the thousand years should be fulfilled: and after that he must be loosed a little season.
Those who died for Christ are raised in the first Resurrection. They reign with Christ for about 3 years.
4 And I saw thrones, and they sat upon them, and judgment was given unto them: and I saw the souls of them that were beheaded for the witness of Jesus, and for the word of God, and which had not worshipped the beast, neither his image, neither had received his mark upon their foreheads, or in their hands; and they lived and reigned with Christ a thousand years.
The Dead wicked(and those righteous that die after the first Resurrection) will not be raised until the second Resurrection at the Lord's coming.
5 But the rest of the dead lived not again until the thousand years were finished. This is the first resurrection.
Those of the First Resurrection reign for about 3 Years.
6 Blessed and holy is he that hath part in the first resurrection: on such the second death hath no power, but they shall be priests of God and of Christ, and shall reign with him a thousand years.
The Seven years are up Satan is loosed.
7 And when the thousand years are expired, Satan shall be loosed out of his prison,
He collects the nations against the camp of the saints(Valley of the Mountain that cleft in the midst) on earth.
8 And shall go out to deceive the nations which are in the four quarters of the earth, Gog, and Magog, to gather them together to battle: the number of whom is as the sand of the sea.
Once they have encompassed the Valley of the Mountain, Christ returns and destroys all flesh and the earth with fire.
9 And they went up on the breadth of the earth, and compassed the camp of the saints about, and the beloved city: and fire came down from God out of heaven, and devoured them.
The devil and the False prophet are cast into the lake of Fire.
10 And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet are, and shall be tormented day and night for ever and ever.
The first and second part of heaven are destroyed, this is at the same time as the two previous passages.
11 And I saw a great white throne, and him that sat on it, from whose face the earth and the heaven fled away; and there was found no place for them.
The righteous dead(that died or were not part of the first resurrection) and the wicked dead stand before YHWH and are judged and sentenced for their deeds.
12 And I saw the dead, small and great, stand before God; and the books were opened: and another book was opened, which is the book of life: and the dead were judged out of those things which were written in the books, according to their works.
13 And the sea gave up the dead which were in it; and death and hell delivered up the dead which were in them: and they were judged every man according to their works.
14 And death and hell were cast into the lake of fire. This is the second death.
This is how it all happens sister.
