I don't know about you, but as I type this I assure you I have both body and spirit together and that makes me a living soul. Every living human is the image of Adam; i.e flesh & blood. Since being a spirit equates to having life, and having the Holy Spirit equates to having life everlasting, I'm very happy to say I have the Spirit from Christ within me also as I write today.
Yes, I am a living breathing complete soul, as God designed every living creature with life would be in this world. Yes, my spirit, but not my body of death, will ascend to heaven a spirit soul (alive) after I die. Because only my spirit will continue to have life after my body dies. Because the Spirit of Christ with my spirit will continue to give life to my spirit in heaven until my spirit is reunited with a new immortal and incorruptible body when Christ returns again and resurrects every single human body from the dead to stand before God in judgment. Where if we be found righteous will live with Christ forever as complete living soul, or if we be found unrighteous, cast into the lake of fire.
After Christ was resurrected, before He ascended to heaven, He went to the place of the dead reserved for the righteous dead (Abraham's bosom) to take those who had died in faith before He came to heaven with Him. Now the OT faithful saints are with Him in heaven where all believers, as spirit alive ascend the moment our body of flesh breathes its last. For the Old Covenant faithful saints who had died before the advent of Christ, this would indeed be the first resurrection, or partaking of Christ's resurrection life as spirit soul (alive), without a body ascending to heaven with Christ from the grave. Because Christ is the first resurrection of all who have died in faith before He came, as well as the first resurrection for all who die in faith since He has come. (1Cor 15:20)
Now Paradise is in heaven (Lk 23:43, 2 Cor 12:4, Rev 2:7) and is the place for living spirits. It is not a place where flesh and blood can dwell because Paul tells us flesh and blood will not inherit the Kingdom of God (1Cor 15:50).
Paul points out Adam's dead corruptible flesh cannot enter Paradise. God's permanent incorruptible physical bodies are in Paradise.
"For we know that if our earthly house of this tabernacle were dissolved, we have a building of God, an house not made with hands, eternal in the heavens."
Adam's dead corruptible flesh returns to dust and is temporal.
God's living incorruptible physical bodies are permanent and waiting in Paradise for us.
It is immediate. Not X number of years after the fact.
This is not even the Millennium, because Adam's dead corruptible flesh cannot exist in the Millennium either. There is no more sin, and only eternal righteousness.
Our spirit is not our breathe. Same word, but different defining points. Our breath is not the putting on of immortality. The physical body needs breath. Putting on of our spirit is the final step of the image of God, the putting on of immortality.
When you put on the spirit, you will shine like a star. When Moses was on mout Sinai, God started to rub off on him so to speak. Moses was not given his spirit, but his face began to shine so bright, he had to cover his head, when he was with his people. On the mount of Transfiguration, Jesus demonstrated the effect of having on the spirit. John symbolizes this by a robe of white. It is put on over the physical body. Adam and Eve had on this spirit over their physical bodies.
When Adam disobeyed God, it was taken away. Their permanent incorruptible physical bodies were taken, and Adam and Eve were given dead corruptible physical bodies. They both died physically and spiritually. That is why they were naked. They no longer had on the robe of white.
Now the church was given the Holy Spirit to live within, not put over our physical body. A demon is a spirit that is no longer a light, but darkness, and can possess a person. God can send a spirit, that we cannot see to influence us like was shown in the OT. But this spirit is not our breath, it is the completed image of God. God is light. The image of God as a son of God is light.
