I certainly agree that's a possible interpretation... two things that lead me to see it differently are that verse 45 and verse 47 are talking about Adam and Jesus... so it makes sense, to me, that verse 46 is to... also, God is a spirit, John 4, so if natural is always first, should we think that God was natural first?... yes, definitely, Jesus is creator of all...
The scriptrue is clearly defining the order in which all things were created and how salvation works in comparison. The order cannot be changed without messing up the entire plan of salvation.
You wrote,
"should we think that God was natural first?" No, we shouldn't because this scripture in 1 Corinthians 15 is describing a "new birth" in Christ, an allegory, using creation as an example. You might have forgotten verse 44 "It is sown a natural body; it is raised a spiritual body. There is a natural body, and there is a spiritual body." However one wants to think, it is still proven that the earthly natural (flesh) has been created first, and through Christ the spiritual follows in every case when the children of God are born again. As we know in Genesis the natural is created by the heavenly Spirit of God, and on earth the spiritual is given after the natural is created. Therefore heavenly and earthy are different in explanations given in scripture.
1 Corinthians 15 Verses 48 and 49 which also should be taken in context "As is the earthy, such are they also that are earthy: and as is the heavenly, such are they also that are heavenly. And as we
have (past tense) borne the image of the earthy, we
shall (future tense) also bear the image of the heavenly."
With all due respect, your explanation sounds somewhat like an evolution theory. Psalm 41:13 Blessed be the LORD God of Israel
from everlasting, and to everlasting. Amen, and Amen.
God is not of a natural body as we are, but the Son became flesh as John describes in John 1:14. Isaiah61:1-3
1 The Spirit of the Lord GOD is upon me; because the LORD hath anointed me to preach good tidings unto the meek; he hath sent me to bind up the brokenhearted , to proclaim liberty to the captives , and the opening of the prison to them that are bound ;
2 To proclaim the acceptable year of the LORD, and the day of vengeance of our God; to comfort all that mourn;
3 To appoint unto them that mourn in Zion, to give unto them beauty for ashes, the oil of joy for mourning, the garment of praise for the spirit of heaviness; that they might be called trees of righteousness, the planting of the LORD, that he might be glorified.
Jesus said of Himself when reading Isaiah "The Spirit of the Lord is upon me, because he hath anointed me to preach the gospel to the poor; he hath sent me to heal the brokenhearted , to preach deliverance to the captives, and recovering of sight to the blind, to set at liberty them that are bruised, to preach the acceptable year of the Lord." (Luke 4:18-19)
John 4:24
God is a Spirit: and they that worship him must worship him in spirit and in truth.
It is clear that God is a Spirit who is not created, and is
from everlasting, and to everlasting.
God cannot be physical (natural) for He is invisible according to scripture. When the Bible talks about Moses and others seeing God face to face one must understand that He can show Himself in any manner He desires for His own glory. As children of God through Christ Jesus we should concentrate more on the spiritual aspects of truth rather than the carnal or physical aspects which are very limited in comparison to the grandeur of God Almighty.
1 Timothy 1:17 Now unto the King eternal, immortal, invisible, the only wise God, be honour and glory for ever and ever. Amen.
