Souls go to be with the Lord but it is taught in the bible that there is a physical resurrection of the body of those in Christ first, then 1000 years, then everyone else to stand judgement. What John saw in Revelation 6 after the 5th seal was not bodies but souls. He specified that they were souls so he knew by sight that there was something different about them, and they were clamoring for justice to be done and for their murders to be avenged, they were not overjoyed and happy, they were missing SOMETHING. There were tears to be wiped away, grief to be comforted, anger to be quenched. God told them to be patient.
So while departing from the body is better than living on earth, we are with the Lord, and we won't be in sin any longer, but we are not whole, we will be waiting for the redemption of our bodies before we are whole, before the Lord wipes away all tears and before there will never be sorrow or grief again. That all comes with the resurrection and is fulfilled completely with the new earth.
Now, note that in Revelation 7 there are a bunch of new people in heaven and John does NOT call these souls, just a great multitude. I believe this is the saints, both those who were dead in Christ, and those still alive at the time of the rapture after the 6th seal, note the change in tone between the disembodied souls.... and the redeemed which I believe have been resurrected in a body and are whole.
Revelation 6:9-11
These souls complain, they ask God for something they need, they are not whole, they are not fulfilled and full of joy, they have an unfulfilled need.
Now compare with Revelation 7:9-12
What a tone change! They go from complaint to praise, something happened to fulfill them to where they didn't have an unfulfilled need anymore. I believe having a body is the difference.
So this is not something that happens immediately after your death, but something we wait for, and will happen to all of us all at once.
1 Corinthians 15:51-52
Paul teaches both a physical resurrection later and each time a person in Christ physically dies. Which version of Paul is correct? Even your verse 52, states they will be raised incorruptible. Meaning they have been already changed. They will be raised, from where? Paradise. Except Paradise is where those alive will be changed and end up as well. That is the point, most refuse to see, because they have been taught wrong. The church will be in Paradise for the last 1000 years. Those amil are right in one thing, it will just be a day for them, if they are in Paradise. I doubt God will judge them for getting that time wrong. Some amil are wrong in other doctrine and theology though, so only God knows what will happen to them.
What those in the 5th seal are missing is their robe of white, not their incorruptible body. The robe of white is their spirit. Paul says there are two changes. We get a new physical body, and will put on our robe of white, our spirit will once more cover us in the light of God’s glorious image. There will no longer be a need for the sun or moon. We will be a body of light. Adam had that image in the Garden before he disobeyed. The sons of God on day six, both male and female had that image, and there were many created on day six, and Adam was one of them. That is the restoration of the 5th seal. In the Rapture of the 6th seal those alive and remain in Christ will be changed bodily and put on their spirit in the air. Also the 144K on earth will be sealed in a similar way. Then the 7th seal will unlock the Lamb's book of life. Then names will be blotted out as the Lamb and the 144K start the harvest and separate the sheep from the goats. The goats will be removed from the Lamb's book of life. The sheep will die and be raised at the resurrection in Revelation 20. When the 6 Trumpets are over, it will be 7 Thunders. This will be the harvest of the Nations. Will there be battles to fulfil more prophecy? We are not told. But the wheat will be harvested like the sheep and resurrected in the new Millennium. The tares burned with fire and removed from the Lamb's book of life. Then will come the celebration and the harvest of the 2 sickles, of the winepress of God’s wrath. Will there be anyone left on earth?
Satan has hedged his opportunity by causing the great falling away in 2 Thessalonians 2. The apostate church left millions of unharvested souls who will never be a part of the church now. These souls will get to spend 3.5 years with Satan in control of the whole world. Those who get their head chopped off will remain in the Lamb's book of life. Those who worship Satan will be removed from the Lamb's book of life. Those who endure to the end, will be removed from the Lamb's book of life, and all will be gathered and killed in the battle of Armageddon. That will complete the tribulation. That will complete Adam's fallen descendants born with a sinful nature. No more sin as in today's current condition. Will there be a consumation of all things in fire? It will not be a Flood. But the day after will be the new heavens and earth of Isaiah 65. This current world still has the last Millennium to get through. But this resurrection of Revelation 20 is not the church. It is the sheep, wheat, and those who refused to worship Satan, and were beheaded instead of wearing the mark 666.
These are not in glorified bodies. They have incorruptible bodies free from the nature of sin. They will repopulate the nations. They will be under the iron rod of Christ. There will be death, because Isaiah claims death is still considered a curse. It will not be like before Adam sinned, absolute perfection. And as pointed out, rebellion will be fomenting, and ready for Satan to once again deceive billions. Amil will not even accept this plan of God's, even though it has been written out by John as John actually witnessed it. It was placed in the Bible at the proper time. Can any one today accept anything as being inspired by God? Quite a few think they are, claim they are, and yet they still cannot agree on all points. If there is a concensus it is liable to be considered just a part of a one world religion, because no one trust any one else but their own understanding. We are, to the point, in the OT prophets, where every one did that which is right in their own eyes. Yet God warns us to never lean on our own understanding, but to trust in God, even if it does not make sense. When we acknowledge God, He will direct our path.
