They stand before God as spiritually dead, physically alive for Judgment. The dead are judged according to what they have done while physically alive, by what is written in the books, and the book of life. Since the dead have not partaken of the first resurrection through Christ in time (a thousand years), they are physically resurrected for condemnation in the lake of fire.
The problem is they don't stand after a physical resurrection. If they are given a physical resurrection, they won't be cast into the LOF. You make a claim the verses don't make. Those dead souls are judged, prior to a resurrection. Judgment always comes prior to a resurrection.
"And I saw thrones, and they sat upon them, and judgment was given unto them:"
A soul has to stand before a throne of judgment before given life.
Those in verse 4 do not stand before the GWT. They stand before thrones, plural. You speculate there could be a resurrection in verse 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."
If so, it is after they have been judged, not necessarily the means to arrive at the judgment. The dead are not standing there because of their works. Where they end up is the result of their works. You are forcing the result prior to the pronouncement of the judgment.
If they receive your spiritual resurrection after physical death, how can you maintain it only comes prior to physical death? You are not being consistent. The first resurrection is physical and comes after physical death, which is a consistent teaching. The second birth happens prior to physical death, and places us into life without having to be the dead standing at the GWT, in the first place.
Even some pre-mill agree with you, that even those in Christ are still in death, until the GWT. Some claim they are on the earth. No one seems to get the point they are already in Paradise, and return in the New Jerusalem. Revelation 19 is not the same event as the New Jerusalem coming out of heaven, but that is how Amil erroneously see it. Those dead have to be physically killed before they stand, as the dead, at the GWT 1,000 years later.
If Revelation 19 is the New Jerusalem coming down why kill them at Armageddon? They could just as easily stand at the GWT prior to physical death as after physical death, since you claim they have to have a physical body, just to stand at the GWT. The reason they are dead is because they no longer physically live on the earth, until the thousand years are over. But they still stand as dead souls, as there is no longer a heaven and earth as they stand as dead. The physical is no longer necessary, unless they are given a physical body as the result of the judgment handed down. With the first resurrection, a physical body, it is no longer necessary to receive the second death. That physical body makes them blessed, as God has removed them from death into life, in a permanent incorruptible physical body without sin, nor a sin nature.
Even your resurrection back into Adam's dead corruptible flesh would not prevent them from dying the second death. In fact in that body, it would necessitate the second death, as Adam's dead corruptible flesh cannot inherit eternal life. Yet you deny the first resurrection is physical, but only spiritual, thus it cannot even happen to those at the GWT. So you have no resurrection. All you have are souls being emptied out of death and sheol, directly into the LOF. That is not a resurrection at all, but a death sentence to the second death. Standing at the GWT is the giving of judgment to these soul's eternal destination. It is God passing judgment accordingly from the books opened. Amil point out some to eternal life and some to eternal damnation in the LOF.
The only way John 5:28-29 can work as a resurrection is that some of those dead are granted eternal life while the rest still reside in condemnation and cast into the LOF. This literally has nothing to do with the redeemed church who received the second birth prior to physical death. Those resurrected at the GWT are still in the Lamb's book of life and they decide then and there to remain in the Lamb's book of life. They are granted both the second birth and the first resurrection, which you have conflated all along. While the judgment is based on their good works, they still are choosing to remain covered by the Atonement Covenant, which produced those goods works, even while they themselves, while physically alive, rejected God's free gift of the second birth. They still cannot boast their good works saved them, because they did not. They still had hundreds and thousands of years in sheol as punishment. What remaining in the Lamb's book of life at that point is, is still salvation from the second death, which all redeemed, have already escaped, while even avoiding years spent in sheol.
Your interpretation ruins what the resurrection even is, if all it is, is a physical body in the LOF. The point of the first resurrection is to escape the LOF, not endure the LOF with a physical body. Will all souls be cast into the LOF with their dead body and demonized spirit? That is a possibility, but not a prerequisite to prove your Amil bias. Your Amil bias claims the second birth and first resurrection is the same thing, when obviously they are seperate phenomenon. The second birth prevents one from spending time in death or sheol. The first resurrection prevents one from the Second Death in the LOF. None of your proof texts can refute that. Only a twisted and contradictory interpretation popular with Amil can refute God's Word, obviously to no avail. So it is not Scripture that goes against pre-mill thought calling for a future Day of the Lord called the Millennium Kingdom. It is Amils and their own interpretation that is actually contradictory to Scripture, no matter if they quoted the entire Bible.
And many pre-mill are wrong as well, when Amil do point out their inconsistencies. But still interpretation is at fault. Amil cannot prove from Scripture denial of a future 1,000 year reign. Nor can they prove Revelation 20 is the here and now.
