You seem to be getting hung up on semantics. Call it "spiritual", call it "incorruptible", "immortal", whatever you want. The question is, do you think that those who were resurrected when Jesus died, and also Lazarus, do you think these people were resurrected in the body that can enter into heaven? Yes, or no?
It is not semantics, although most use the terms that way. It is physical and spiritual. It is being born of the flesh and the spirit.
No one will be born of the spirit until the Second Coming. That is why it is semantics to many. They want the spirit now. Only the Holy Spirit is given now. We have no access or control of our spirit until the Second Coming. Most do not want to hear that. Guess what? Those before the cross did not have an incorruptible body, but a soul in Abraham's bosom. Those born before Christ were not even allowed in Paradise upon death. The spirit is not restored until the Second Coming.
David said he had to sleep in the ground, and that was the closest thing to eternal life. The Cross changed that because Jesus Christ provided a physical resurrection. Not one that was future. It was the second Jesus said, "It is finished". They all received physical incorruptible bodies. All souls in Christ at physical death were immediately given a physical incorruptible body. No more physical resurrection was needed for those souls who used to sleep in Abraham's bosom. That was the physical victory over death, the removal of the sting of death. No one teaches that or accepts that, so we get semantics. We call the physical resurrection "spiritual". It is not spiritual, ethereal, or figurative. It is literally physical. Done and over with for those in Christ. God is the God of the living incorruptible physical body humans. Not the God of the dead corruptible flesh and blood bodies from Adam.
Our souls are given the Holy Spirit as credit, because even those in incorruptible physical bodies in Paradise have to wait for the Second Coming to be joined with the Second Life, our robe of white, glorified bodies of light, known physically as our spirit. Spirit is not a life force like a ghost or ethereal body. That would be the breath of God making us living souls. Some would say a fetus cannot be a soul, until the breath of God enters the physical body. Some say that happens at conception. The Holy Spirit seals every single descendant of Adam at conception. All have a right to reject that Grace of God and choose to seal their own souls with their own "right"ness.
Our spirit at conception because of sin remains with God, and the Holy Spirit seals us, until the day we physically die. Those in sheol are not sealed by the Holy Spirit. Those in Christ are redeemed and given an incorruptible body that is permanent in Paradise. The Holy Spirit does not have to seal once a soul is in their permanent home.
Now there is a day when a soul makes a choice to accept God and with that choice another choice to be led by God and allow the Holy Spirit to work. That changes the mind which is the soul. That does not give you access to your spirit. That does not give you an incorruptible sin free body. Salvation is not a physical nor spiritual change. It is the soul changing from heading to destruction to heading to eternal life.
Is salvation what the verse is talking about when Jesus calls us out of death into either eternal life or eternal damnation? Because most claim that does not happen until the last day of physical time, not the last day of a personal choice to accept God's Atonement. Yet I would go with the former instead of the later. Do you think we have a choice in the matter? Some would say, no, only God decides our fate. What is the point to spread the Gospel or good news, if on the very last Day, God still gets to decide? Why even die on the Cross, if it only covers a few any ways?
No, the Atonement covered all of Adam's descendants. All have a free will choice to accept or reject. The Day of Redemption was on the Cross. The day the Holy Spirit stops sealing is when the Cross takes affect, or when one physically dies. The Cross covers those who physically die in Christ, because the soul immediately enters a permanent incorruptible body in Paradise. Those who reject the Cross will only have a chance at the GWT.
If their original body is given back to them, what is the point? To be eternally reminded of their flesh? Every one quotes verses yet never is dogmatic about either an incorruptible body that can die again, or a corruptible body that can die again. There is nothing about either that can save one from dying again. To just claim to have a body of flesh would mean taking care of a body of flesh in the Lake of Fire. Do they have bodies now? Abraham was said to talk to souls on the other side. People claim to talk with dead bodies all the time. Is it a body or a soul that looks like a body? Sorry but one can stand before God with a soul that looks like a body.
That is the claim (of many) of those souls under the alter, although my claim is they already have an incorruptible body. Many claim the dead in the first resurrection are still dead physically. What was raised then? SG claims it is us living in the first resurrection. We have dead corruptible bodies but some sort of "spiritual" activity going on now. What about the church in Paradise, same spiritual activity but no physical activity at all? How can we have the same spiritual activity, and we are blind to evidence while those in Paradise do not seem to physically control those on earth?
That would be demon possession. Is there a battle going on between souls in Paradise and those in sheol? It is only semantics to those who refuse to define their terms like Paul does about the physical and spiritual aspects of the soul. The physical deals with the body. The spiritual deals with the spirit. It is still one physically created being in the image of God. How many people walk around like Jesus with a transfiguration physical body of one's spirit on them like a robe of white (light)? It is certainly not hanging up in a closet in their home.
Jesus did say you have to have a physical body first. Not a dead physical body. Then after that you can be born with a spiritual body. No, Nicodemus, you cannot be born the second time in your mother's womb. You have to physically die, so the soul can enter the incorruptible living permanent body. That is the first resurrection. Jesus did not even have to die to get His incorruptible body. Unless you accept His corruptible one went back to dust in the tomb within 72 hours.
Then all souls have to wait, even those in Paradise, until the second coming to be glorified and reunited with one's spirit. Then the church will be complete and fully restored sons of God in the complete image of God. The image that the dead soul of Adam lost when Adam disobeyed God. Dead because Adam was changed physically and spiritually at that second. Incorruptible body to a corruptible body, and his spirit was taken away to be with God. Immortality to mortality. The same change in reverse order to those alive at the time of the Second Coming. It cannot be called death. It can only be called coming to life. It was called death and was literally death for Adam who was now a dead soul. Yes Adam lived hundreds of years in a corruptible dead body, physically. An incorruptible body is without sin. An immortal body is one's spirit, the robe of white (light). The term used by Paul was Greek. But the Greeks use Satan's definitions, and the church taught Satan's definitions. Immortal meaning divine unable to die, yet all Greek gods are dead or never existed. Mortal meaning human capable of death. God's definition is being glorified like God, because God is a Spirit and God is Light. Both equally physical attributes associated with God in the form of God's image of being on earth. Humans were literally being God Himself on earth enjoying His creation, yet mere beings created by God in God's creation. Letting the Holy Spirit control one's life is as close to being spiritually saved as one can get. We are not with our spirit, because this corruptible carnal flesh cannot take on our robe of white. And those in Paradise in incorruptible bodies also have to wait.
Now some claim they cannot even have incorruptible bodies. Yet they had to have had bodies when they came out of their graves at the time of the Cross. They could not have them prior, because God Himself had to come to earth to take care of sin. Jesus told the thief on the Cross, today, that day, Paradise and incorruptible bodies were made possible on the Cross. The soul has to first have a physical body. In the future at the Second Coming the soul will have a spirit. We have a spirit that is constantly in God's presence. It testifies to all we are. If it cannot and becomes a demon, that is when a spirit is sent out into the world. We are not told the how and why, because the occult is forbidden to humans. We just know that demonic spirits can possess living humans who mess with the occult. The only physical being ever created with a spirit are humans on the 6th day. Jesus was telling Nicodemus how the dead soul could be restored in an incorruptible body, and at the Second Coming be born of the Second Life, our spirit, robe of white.
The first resurrection and the Cross restored the physical incorruptible body. The Second Coming will restore the spirit the Second birth and Second Life. The soul is dead, until quickened with accepting the Atonement. Physical death restores the incorruptible body. The soon Second Coming will restore our spirit to our incorruptible body.
The Second Coming is over and completed by the 7th Trumpet. The resurrection after Satan's 42 months only applies to those beheaded during those 42 months. John does not say, however, the restoration of the sheep, the Nation of Israel, and the restoration of the Nations, the harvest of the wheat is also tied into that resurrection, as all those humans will populate earth in incorruptible bodies for 1000 years. The rest of Adam's dead souls remain dead souls until the dead souls stand before the GWT.
Many have taught a second chance "gospel" here at the GWT. Are there names still found in the Lamb's book of life, which was opened just after the Second Coming in the 7th Seal. Many had been in sheol for thousands of years before any names could even be removed. Names were not removed while the book was sealed. If that were possible, Moses claimed he would have his removed so all of his people could be saved instead. Perhaps that was just a figure of speech? It was impossible either way. The first time we see names not there is when people take the mark and now their name is not in the book. Do those in sheol take the mark? Are they prevented from an economy in sheol if they do not?
At that day (GWT) God will say, depart from me, I never knew you. How can God be omniscient now and currently never know someone? The act of removing their name from the Lamb's book of life, at that moment, would make it permanent that God never knew them as if they never existed in the Lamb's book of life. Will many at that point choose to remain in the Lamb's book of life? I think that is why many imply there is a "second" first resurrection at that point for some if not many. Just to have a dead physical body is not the same thing.
I would add another point. Those during the 1000 years are born in sin free incorruptible bodies that cannot be touched by the Second death. What about rebellion or braking the Law? Are those born from resurrected bodies even in the Lamb's book of life or covered by the Atonement as they are not from Adam's flesh and blood. Were the original sons of God under the Atonement who were not part of Adam's flesh and blood? These are unknowns and speculations. Part of Noah's Flood was the result off the mixing of genetic lines between humans who were sons of God and Adam's descendants. It is plausible that those living who were resurrected can never die again. Their offspring though are not in the Lamb's book of life. Are not even a part of the church period. The church cannot even have offspring with those born on earth during the 1000 years. For one, the church remains closed up in Paradise until it comes down as the New Jerusalem. Those sitting on the thrones in Paradise cannot come down and intermingle with those on earth. So the obvious point is rebellion or braking the Law is instant Death. Those souls never even get a choice. Their choice was the physical act of rebellion. They were never covered by the Atonement and never will be. They are judged at the GWT on the single act of rebellion and cast into the Lake of Fire. That is why Death is introduced in the 4th Seal just prior to glorification in the 5th Seal. Not being in the Lamb's book of life while physically alive, there is only one choice and it is not based on the Atonement of the Cross at all. It is follow Satan or physically die. Those who take the mark make that choice physically and irreversibly. That is instant Death upon physical death. The same single choice remains for 1000 years under the iron rod. Obey or instant Death. The Second death is guaranteed along with the physical death. Death with a capital D is irreversible. In fact those who are beheaded by that one single choice are the one's resurrected to have future offspring who have that one choice of Obeying the Word of God Jesus Christ the Lamb of God. Satan will not be around, but it seems the second he is loosed, he will instantly have a following of those who after hundreds of years easily reject God and God's plan on the earth. Some even reject the 1000 year plan of God today.
