Neither does God "disown" us today. By His manifold grace, we get a chance to hear the gospel and respond, which is the remedy (by Christ's completed atoning work) for our sin.
You admit that God does not disown us today. Why do you find it so hard to believe that God would not disown Adam? He wouldn't. Adam never lost the salvation that God gave Him when he was created. There is no Biblical evidence to support such an idea.
I'm sensing a disconnect in your thought process on this issue, which seems to be hung up around the concept of Adam not being born into original sin.
Quite true. He wasn't. He wasn't born but created. He was created directly as God's child, not as one of the devil's children as we are (John 8:44; Eph.2:1-3). We are born in sin; Adam was not.
True that -- he was, first, not born, and second, not created a sinner. But, he sinned, and his sin was such that he passed on to the rest of humanity a sin nature.
And please explain how that magically and mystically gave Adam himself a "sin nature" that he didn't have before. If that is not directly stated in the Bible then you are reading into the Bible a very mystical belief.
In order to be heritable, as sin is, it must have first resided in the father of all humans.
That is your philosophy; your opinion. You are entitled to it; but it isn't worth much unless you can back it up with Scripture. Nowhere does the Bible state that sin resided in Adam as in a sin nature. Show me chapter and verse.
Adam committed sin. It was his choice. But choice was not because of nature. Go back to chapter three. Eve never had a sin nature. She came into this world in a state of innocence created in perfection. Yet she was tempted by Satan and sinned. And then Adam rebelled against God and sinned also--both without having sin natures. It was their choice. Sin did not reside in them before hand.
The consequence of that sin was that a "sin nature" (which Adam did not have) would be passed on throughout all generations. That was God's curse because of Adam's sin. It was part of the Fall. Are you trying to tie the hand of God by your own philosophy saying that God can't do things unless he does them your way? I go by the Scriptures, not by philosophy.
What of the "curse of God." Can God curse someone and they not be spiritually dead? Seems rather contrived to suggest otherwise.
The entire line of all of Coniah's descendants were cursed. Part of the curse, though Coniah was related to David, that none of them would ever be heir to the throne of David. Joseph was one of the descendants of Coniah. One of the many reasons why Christ had to be born of a virgin is because of the curse on Coniah and his descendants (Joseph). Had Christ been born of Joseph and Mary he would have been born of a cursed line which would have made him ineligible to inherit the throne of David, as Joseph was.
Jeremiah 22:30 Thus saith the LORD, Write ye this man childless, a man that shall not prosper in his days: for no man of his seed shall prosper, sitting upon the throne of David, and ruling any more in Judah.
--Joseph was under this curse, but what did Joseph do to deserve it?
"Can God curse someone and they not be spiritually dead?" Joseph was.
The entire nation of Israel was many times. Achan sinned and Israel was cursed as they went up against the city of Ai.
Of course the serpent did not repent and trust God. He was God's enemy by choice and remained such (and according to the Word was not offered the chance at salvation as are humans created in the image of God). But, I believe that Adam did repent and trust God even if I cannot proof text the occurrence. The evidence exists in his life after the fact, where he lived according to God's dictates, even though separated from God and from the Tree of Life (the metaphor and reality of a true sinless life for eternity).
Adam repented not to gain salvation (that he already had), but in order to restore fellowship with God. He never lost any salvation. Adam and Eve clothed themselves with fig leaves. God clothed them with the skins of an animal, the outcome of the sacrifice that God himself provided for them. God provided a sacrifice not to give them salvation, but to restore fellowship between God and Adam.
I'm also noticing that you make the same error in your thinking about being "born again" as did Nicodemus in John 3: John 3:4 (ESV) Nicodemus said to him, "How can a man be born when he is old? Can he enter a second time into his mother's womb and be born?"
Being born again has nothing at all to do with physical birth or in the case of Adam, being created instead of birthed.
It has everything to do with
two births!
If you are born once you will die twice.
If you are born twice you will die once.
It has everything to do with God bringing the imputed power of the atonement into the "dead in sin and trespass" individual and making them "a new creation." I believe that this happened to Adam, as it did to any or every other OT character who was saved in the biblical way, by grace through faith in the only name that brings salvation, Jesus.
It couldn't happen to Adam. Adam never lost what God gave him at creation. Scripture does not bear this out, and you haven't given anything but ideas. Where in the Bible does it say Adam lost his salvation or needed to be saved? It doesn't. And for all your posts, you haven't given any Scripture or evidence that convinces me that Adam was ever lost.
