You're right, "flesh and blood" cannot....but "flesh and bone" can Lk 24:39 (but that's a whole other conversation).
Do you think that God cannot change our physical form to be able to inherit the Kingdom? The key verse for understanding the state of resurrected body is Rom 6:5, 8:11 and 1 Cor 15. Some might ask "how are the dead raised?" The "spiritual body" is defined for us:
"For this perishable must put on the imperishable, and this mortal must put on immortality. But when this perishable will have put on the imperishable, and this mortal will have put on immortality "
The change we will undergo is an addition of a 2nd nature we once had not.
Our natural bodies will "put on" the spiritual. Its a permanent reunion of something that Adam fragmented, but Christ restored.
What do you think Adam and Eve were clothed with before the fall?
One of those mysteries with many approaches under the the light of God's word we can have some success in seeking His approval . Something that will ruin (death through corruption) cannot have a part in something that never ruins.
I would ask. What
kind of flesh did they have before the fall, before corruption as the result?
What the bodies were before the fall just as what will our new bodies be like?
No one knows what they
were or what they
will be.
The new creation is not a rebuild. The corruptible leading to death does not put on incorruption, a bandage .
The beginning is different than the first beginning. Not subject to the letter of the law death by corruption (dying) .
The new (neither male nor female, Jew nor Gentile) will not be made up of the old rudiments. Perhaps a new periodic Table element chart with a different foundation other than carbon base. No one knows.
Christ cannot be found under a microscope .
Their whole body soul, spirit and mind were under the letter of the law, death, the temporal .
I think prior to pride and the fall man was clothed with light showing the presence of God. God is light. That light vanished and their nakedness' the temporal corrupted was seen . They used fig leaves as if it was the light of God's presence. His glorious countenance shining brighter than the Sun . Fig leaves are for temporal healing in parables (all nations)
He knew what was on the other side of the fig leaves . He makes as our Faithful Creator our ears, eyes, and private parts.
Some say God slew a lamb rather than removing his glorious presence from their lives in order to show their nakedness (without God) .
Unto Adam also and to his wife did the Lord God make coats of skins, and clothed them. Genesis 3;21
The glory departed . Referred to as Ichabod,
Coats of skin flesh without the spirits witness .
Moses gives witness coming down from Mount Sinai it used in that parable to represent the kingdom of God with God as the light. . Moses who represents the law of God coming from the presence of the glory of God . A veil to represent suffering flesh was needed. No man could see the face (presence) of God and live, we see him faith to faith . God is not a man .
Nothing about any lamb being slain again . The Son of God working with with the Father was slain from before the foundation of the world . It was demonstrated outwardly in the new testament much later than Genesis. Jesus corrupted flesh during that demonstration of Him and the father did not profit as a unseen work of one faith made possible by two .We continue to walk by
faith the unseen eternal . The revealer of the unseen glory, our living hope.
Jesus' flesh and not his perfect spirit was signified as sinful in Romans. That was in order to do what the letter of the law "death " could not do. Create a new creature in respect to the lamb of God . . . again
was already slain before the foundation.
Before the fall not a after thought that leads to a action .
The veil representing the corrupted flesh of Christ is rent from the top to the bottom . The promised glory to follow the demonstration of the sufferings of Christ beforehand. A blessing to those who do walk by faith . From that unseen glorious understanding to the same. face to face to a believer. who does have the treasure of the unseen power of His glory.
Like David in the Psalms lifted up his God. Glory Glory glory . Three to denote a end of the matter.
2 Corinthians 3:18 But we all, with open face beholding as in a glass the glory of the Lord, are changed into the same image from glory to glory, even as by the Spirit of the Lord.
