The spiritual body of Christ in heaven is non-material. It shall be as spirit beings in heaven, celestial/heavenly without a body, but not without life. It will be a spirit or living soul. The body Christ appeared in after His resurrection was not a spiritual body. His body was human with flesh & blood, and the spirit in His body gave life to His body. He was then with body + spirit a living soul. I do not believe your understanding of what a spiritual body means aligns with Scripture. Immortality does not make a spiritual body. Immortality makes a body of flesh & bones that shall never die. Spiritual life comes from our spirit through the Spirit of Christ in us. A spirit is not visible, that's why I don't believe our physical bodies will be resurrected spiritual bodies. They will be resurrected immortal & incorruptible alive forever through our eternal, invisible spirit in them.
That would be your limited sinful flesh view, that a body and air equals a soul. That is not what Paul taught. You cannot form your opinion of Paul's teaching on a faulty understanding of Genesis 1 and 2.
You are a soul. You are not a body nor a spirit. God's breath on the 6th day was more than just God's "created air". Just because the Hebrew word has meaning, that is not what is later defined as a person's spirit. We are not air. We breath air in and out to stay alive. Our spirit is not the air we breath. If that were the case then everyone's spirit is out there creating all the air in the world.
You claim a body and a spirit (air) come together and form a soul. The simplest interpretation is that it was God that made us a soul. Then you assume it took a body and air. Paul does not say 1+1=3. Paul says we are a soul 1 + we have a body to put on 1 + we have a spirit to also put on 1 = 3. Our spirit cannot be air, because we cannot put on air, as air is what we breathe in and out.
Now the Holy Spirit works from the inside. Demons work from the inside. But Paul never any where says receive your spirit from God and place it inside you. Paul points out it is mortal putting on immortality. John in the 5th Seal calls it putting on a robe of white. Neither called the spirit by the term used in the Greek so as not to confuse "air" which is the Greek meaning of spirit. The same word is used for spirit and air "pneuma". We can see right there our spirit is not "pneuma" "air". But no one wants to acknowledge that immortality means more than just longevity. You don't put on longevity. Paul is literally saying death puts on non death. But what is Paul attempting to convey if we put on more than longevity and "non death"? We put on the spirit, because Adam lost the spirit when he disobeyed God, and no human has had a spirit on earth since then. Yes we have a spirit, but the spirit resides with God in the presence of God. We can see that in 1 Kings 22:19-25.
Most interpret the word immortal or immortality as an adjective. But Paul uses the word as a noun. As an adjective it means longevity. As a noun it means divine or carnal gods. When Adam disobeyed, he lost his standing with God as a son of God. That would be his spirit. It was taken from him, and he could no longer communicate nor speak with God face to face. That is why he hid. He knew he lost that spirit. He was also naked after loosing the spirit. That is what Paul said that we put on the spirit. It was put on over the physical body.
And Adam physically died as well. His soul left the permanent incorruptible physical body that Paul defines in 2 Corinthians 5:1. That is when he was placed into death as a mortal. He now had a temporal corruptible physical body, that in dying would keep dying until physically dead, and returns to dust, dissolves back into the earth. Just as Paul declares in 2 Corinthians 5:1
So there are two different bodies. The one we are born with from Adam. And the one God gave Adam and all the sons of God on the 6th day. So Paul declares the soul puts on incorruption and immortality. The soul puts on God's permanent incorruptible physical body, when it leaves Adam's dead flesh. But putting on the spirit happens to the entire church at the Second Coming, the 5th and 6th Seal. We don't put on longevity. No such thing as immortal body in Scripture. We put on a physical body and the spirit. And Jesus showed us what the spirit is on the mount of Transfiguration. He started to shine like the sun. That was an outer phenomenon, not an inner phenomenon.
And when Paul says to live as to keep the soul and spirit blameless, he is saying that some being so wicked can literally turn their spirit into a demonic spirit. Demons are the spirits of past dead humans, not a third created entity besides humans and angels. They are spirits that can invade a person's mind and soul, and literally take over thus creating more demons.
But accepted theology does not teach this, because Satan does not want us to have all the facts, but keep us in the dark with half truths. It does not even take that much to figure it out, even though you all keep preaching we need to be spiritually discerned. You have all seemed to accept human theology as the only discernment we need.
You seem to accept Paul's symbolism of a plant that no one gets a body until the end, obviously a plant needs time to grow from a seed in the ground, but then fail to see Paul is addressing those alive on the earth at the Second Coming. Not those already in Paradise in permanent incorruptible physical bodies. No soul or body is in the ground when the soul leaves this body of corruption. That is not the point. The point is only, there are two different body types but both are physical. One is of earth, natural from Adam. The other is of heaven, spiritual from God. But not an "air body", an incorruptible and permanent physical body. Adam did not have an "air body" before he disobeyed God.
In fact those sons of God were considered giants and men of renown, that lived from the 6th day creation. Adam's dead flesh seemed to even be diminished in size and what it could do after Adam lost his original physical body. Life would be way harder than it was originally.
BTW, God declared Adam would die. That was not some philosophical notion that death was inevitable, and eventually realized. The philosophical notion that many declare is the philosophy Satan used on Eve, saying they would not certainly die. Why chase Satan's deception as the real thing? They did indeed die. The reversal is necessary to go from one type of body, back to the original body Adam had. If you accept Paul literally defined two different bodies, then Adam had two bodies, one before disobedience, and one after disobedience. Call that a change, but there were two distinct body types. The soul changes bodies. Not that one type morphs into the other type. Paul said the body is put on. Like clothing, you don't have just one set that can change its physical properties. You have several sets of clothing you change in and out of. Paul explains there are two bodies, not one that changes it's properties.
