Greetings brother JD
So based on what you just said and sticking to the OP. Where does this lead? Is it Persaverience of the Saints? Once Saved Always Saved? Or can one lose their salvation?
Peace to you brother
If one understands the sonship of the born again believer he will have no need to make up non bibilical descriptions for his position. God says we are all sons of Adam and are in his family through our physical birth. We are not sons of God by that kind of birth. We must be born again the scriptures say. That is as much of an event as being born physically into the family of Adam. Does being born again mean we lose our identity as sons of Adam? I trow not. We are in no danger of being unborn physically. One cannot be unborn. He can be cast aside. He can be disinherited. But his birth was an event that is sealed in history.
But the body we live in was the only thing we received through our birth into the human family of which Adam is the head. We did not receive our spirit from him. The spirit identifies our personality. It is who we are. we are eternal. We will still be the same person long after our bodies die and returns to dust and our soul is separated from it. The soul then is the spirit of man. It is given by God when we are conceived.
1 Remember now thy Creator in the days of thy youth, while the evil days come not, nor the years draw nigh, when thou shalt say, I have no pleasure in them;
2 While the sun, or the light, or the moon, or the stars, be not darkened, nor the clouds return after the rain:
3 In the day when the keepers of the house shall tremble, and the strong men shall bow themselves, and the grinders cease because they are few, and those that look out of the windows be darkened,
4 And the doors shall be shut in the streets, when the sound of the grinding is low, and he shall rise up at the voice of the bird, and all the daughters of musick shall be brought low;
5 Also when they shall be afraid of that which is high, and fears shall be in the way, and the almond tree shall flourish, and the grasshopper shall be a burden, and desire shall fail: because man goeth to his long home, and the mourners go about the streets:
6 Or ever the silver cord be loosed, or the golden bowl be broken, or the pitcher be broken at the fountain, or the wheel broken at the cistern.
7
Then shall the dust return to the earth as it was: and the spirit shall return unto God who gave it.
In case you missed it the Preacher is talking about the body and soul, the natural man. In this condition all is vexation and vanity. It is a vain life if this is all there is because the body gets old shortly and goes back to the dust from where it came and the spirit is separated from it and goes back into the hands of God, who gave it, to face judgement for every deed of the body whether is be good or bad.
13 Let us hear the conclusion of the whole matter: Fear God, and keep his commandments: for this is the whole duty of man.
14 For God shall bring every work into judgment, with every secret thing, whether it be good, or whether it be evil.
The spiritual man is not under discussion in Ecclesiastes.
I do not know if you have ever read with discernment Romans 8 where believers have been made tri-part by the presence of the Spirit of God in the body but it is a must read. Yes the born again man still has the old Adamic dead weak body but now the Spirit is in it and look at the contrast here.
Ro 8:10 And if Christ be in you, the body is dead because of sin; but the Spirit is life because of righteousness.
(NOTE) if one does not define "dead" biblically one will not understand. Dead does not mean cessation of being, it means separated from God. The body is where sin dwells. The soul has been redeemed, the body hasn't. What is the solution. The blood of Jesus washes away sin and forgives the sinner who has received him and the Spirit of Christ is the perfect righteousness that God requires.
Ro 8:8 So then they that are in the flesh cannot please God.
9 But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his.
10 And if Christ be in you, the body is dead because of sin; but the Spirit is life because of righteousness.
11 But if the Spirit of him that raised up Jesus from the dead dwell in you, he that raised up Christ from the dead shall also quicken your mortal bodies by his Spirit that dwelleth in you.
Surely one can see that sin did occupy the body and it was dead but now the Spirit of God and of Christ occupies the body and it is alive. This is the new birth. Going from death to life. Don't miss this.
Ro 8:14 For as many as are led by the Spirit of God, they are the sons of God.
15 For ye have not received the spirit of bondage again to fear; but ye have received the Spirit of adoption, whereby we cry, Abba, Father.
16
The Spirit itself beareth witness with our spirit, that we are the children of God:
17 And if children, then heirs; heirs of God, and joint-heirs with Christ; if so be that we suffer with him, that we may be also glorified together.
Think! If the church is corporately one body and we are one with Christ then we MUST be joint heirs with him if we are glorified together. Glorified means we will each receive a glorified body like his body, but not until the body is fully formed. He has a glorified body at his resurrection. Now you know what we are predestinated to. We are promised, and it is the "blessed hope" that these weak bodies from Adam will be changed and we will have a new body, a glorified body from God like unto Christ's glorious body. This will happen at the rapture of the church after it is fully formed.
When we receive the new body we are once and forever severed from any trace of sinful Adam and we are totally a new creation in Christ Jesus.
Now, with that in mind I will quote just two more verses in this post.
Ro 8:15 For ye have not received the spirit of bondage again to fear; but ye have received the Spirit of adoption, whereby we cry, Abba, Father.
Ro 8:23 And not only they (the creature), but ourselves also, which have the firstfruits of the Spirit (Israel), even we ourselves groan within ourselves, waiting for the adoption, to wit, the redemption of our body.
If you cannot see that from Ro 7:1 through Ro 11:12 the context is primarily to the Jew, who was first to receive the Spirit and the new birth, then you will miss the message and struggle with sound doctrine.
I have answered much more than you have asked but what I have said will help you if you don't already know these things.
May the Lord Jesus be high and lifted up. Amen.
