I'm not making an assumption. Yes, a living soul is what the physical body, and spirit in man is called. Our body cannot continue to have life without our spirit. But our spirit, IF we have been born again of the Spirit, shall never die even though our body will. Eternal life is only necessary for spiritual life, to enter spiritually into the Kingdom of God in heaven when our body dies. That's what Christ means when He says we must be born of the Spirit to know and enter the Kingdom of God. "Ye must be born again"!
John 3:3 (KJV) Jesus answered and said unto him, Verily, verily, I say unto thee,
Except a man be born again, he cannot see the kingdom of God.
John 3:5-8 (KJV) Jesus answered, Verily, verily, I say unto thee,
Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God. That which is born of the flesh is flesh; and that which is born of the Spirit is spirit. Marvel not that I said unto thee,
Ye must be born again.
The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is every one that is born of the Spirit.
Our physical body will never have eternal life to enter the Kingdom of God in heaven after death, for flesh and blood cannot inherit the Kingdom of God. Because it is mortal, and corrupt. Mortal beings cannot be eternal because mortal means to be under the curse of death.
When our physical body dies, we are not unclothed because through our living (soul) spirit we have an eternal place in heaven, and shall be clothed a spiritual body with our house which is from heaven. As long as we are clothed in physical bodies we feel burdened and long to have our mortal flesh swallowed up of life. God has given us assurance of this by giving us His Spirit. When we are absent from our mortal bodies of death, we shall be present with the Lord in heaven clothed in eternal living spiritual bodies.
2 Corinthians 5:1-8 (KJV) 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. For in this we groan, earnestly desiring to be clothed upon with our house which is from heaven: If so be that being clothed we shall not be found naked. For we that are in
this tabernacle do groan, being burdened: not for that we would be unclothed, but clothed upon, that mortality might be swallowed up of life. Now he that hath wrought us for the selfsame thing
is God, who also hath given unto us the earnest of the Spirit. Therefore
we are always confident, knowing that, whilst we are at home in the body, we are absent from the Lord: (For we walk by faith, not by sight
We are confident,
I say, and willing rather to be absent from the body, and to be present with the Lord.
Yes, we speak as having eternal life once we have gone from natural man to spiritual man. But we still have our bodies destined to die, because though we say we have eternal life, we are still mortal man of flesh and blood, and our body will eventually die. The eternal life we possess is through Christ's Spirit in our spirit, who will be with us until our bodies too are resurrected and changed.
Ephesians 1:12-14 (KJV) That we should be to the praise of his glory,
who first trusted in Christ. In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise, Which is the earnest of our inheritance until the redemption of the purchased possession, unto the praise of his glory.
You said, "The soul itself seems to be a combination between the body and the spirit, forming an ego, or identity." You understand the body with the spirit is called a living soul. Calling our resurrected immortal body a spirit-body seems to imply something other than the human beings God created mankind to be on the earth. The spirit is one, and the body is one, and together they are a living soul. After our bodily resurrection we shall all be the living souls God created us to be when He breathed life (spirit) into the lump of clay, and man became a living soul, created with no more sin and with no more death. Our spirit eternal, and our body immortal without corruption for the new heaven and new earth, just as we were in the beginning.
If our body is immortal, meaning it can never die, and incorruptible, meaning no longer will we grow weak, or sick, why would life in our new physical body need to be eternal, since our spirit which animates our body is eternal? Eternal together with immortal and incorruptible = a whole or complete living soul as we were before sin and death through sin spoiled God's creation.
I wonder if you are struggling against the fact that because when the spirit in man is indwelt with the life giving Spirit of Christ, in death we go a spiritual body to heaven? Do you deny eternal life through the Spirit truly means our spirit shall never die? Is that why you seem so determined to cling to our resurrected physical body as spirit-bodies? Even though the spirit and the body are not the same thing.
