Even the body of Christ was destined to die! Every human being is appointed to death that comes through sin. Since all have sinned, all are ordained to physically die. Believers won't receive immortal & incorruptible physical body until the hour that is coming when the last trumpet sounds and time/delay shall be no longer. It is the spirit of man through the Spirit of Christ within that gives believers everlasting spiritual life. The spirit of man having the Spirit of Christ within can NEVER die, even though the physical body of flesh of every man is destined to die.
The body is not resurrected WITH eternal life, but is resurrected immortal and incorruptible through our eternal spirit that returns with Christ when He comes again.
When one is born again through the Spirit of Christ within, they have partaken of the resurrection life of Christ who is the first resurrection from the dead to die no more.
So in 2 Corinthians 5:1 the body from God is not physical but what, dust from heaven?
"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."
It sure seems like Paul is talking about 2 different bodies here. Not: one that is physical and the other that is not physical.
Paul does not say that we have to wait thousands of years for some judgment day.
We are not dead because we sin. We are dead because that is the body and image of death we inherited from Adam through Seth. We sin because the dead do not know God from birth. That knowledge comes from experience. Romans 5:12-14
"Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned: For until the law sin was in the world: but sin is not imputed when there is no law. Nevertheless death reigned from Adam to Moses, even over them that had not sinned after the similitude of Adam's transgression."
Death is passed down even when sin is not imputed. One has to know the Law in order to sin and break the Law.
The example is given of the rich young man who claims to have always obeyed the Law and never once sinned, but when he asked Jesus what he needed to do, what Jesus told him to do was too hard, so he walked away still in a state of death. He would have rathered enjoyed life than obey the Words of Jesus. So once he knew what he had to do, until he did that, he would never find life.
So one could literally do nothing wrong their whole life and still remain in death in sheol until the GWT Judgment. Because they never did the one thing that God would have told them to do, had they sought God out. The point of escaping death is accepting the Atonement of the Cross, the second birth. Escaping death is not just doing your own righteousness your whole life.
The point is that this body of death cannot enter Paradise. But there is a physical body that the soul does receive once one does enter Paradise. No one walks around Paradise without the same body that Jesus has always had. Why would Jesus be the only one with a physical body? His physical body most certainly entered Paradise and the throne area of God where there has always been a temple in heaven. Revelation 7:9-17 has been the physical reality for those in Christ starting with the thief on the Cross. They are not waiting for some future experience. They have been serving God day and night since the Cross. You claim Revelation 20 has been a reality since the Cross, but then deny Revelation 7 after verse 9 has been a reality as well since the Cross.
Why is that?
They are ruling and reigning with Christ on those thrones set up. But that is not what Revelation 20 is even talking about. Revelation 20 is talking about humans who were still physically alive on the earth after the Second Coming.
BTW: Jesus kept the same body He was born with. It did not return to dust, because it was not from Adam, but was the second option in 2 Corinthians 5:1.
"a building of God, an house not made with hands, eternal in the heavens."
Jesus was God, so had that body of God at conception in the womb of Mary. The only destined part was that Jesus was the Lamb of God slain from the foundation of the world.
Jesus' body did not have to die because of being of Adam. But because Jesus was the second Adam.
We know it was the same body, because it had the nail wounds and spear wound. If Jesus had a different body at resurrection, it would not have those marks.
So Jesus could enter heaven at any point after birth. After the resurrection, Jesus could be any where in time with that same post death body with the scars. Jesus was not physically limited by time either.
