A human being is not sinful, what makes a sinner is their nature.
You just contradicted yourself. Adam was not created to sin. He was not a sinner, until he sinned. Everyone else is practically the same. We all fall, and become sinners. We sin because we are sinners. We are not sinners because we sin. It is all anyone can do. We can only sin. This is explicitly pointed out in Romans. Nothing we can do will ever please God. We can never repent. It is impossible for the carnal man to repent. The carnal man must die. It is only the new creature in Christ who can repent and take hold of the good news, and embrace it.
Christ did not have the nature handed down through Adam, which is a sin nature,
He came "in the likeness of sinful flesh"(Rom.8:3).
his father was God (you get a nature by a father).
Look at Christ's genealogy in Luke's gospel. It goes all the way back to Adam. He was "born of a woman". He who denies that Christ came in the flesh is of the spirit of antichrist. 1 John 2:22
That makes a human being sinful not their actions, sinners by nature.
Yes. Agreed. We are not sinners because we sin. We sin because we are sinners. It is the nature of the carnal man to sin. That is all the carnal man can do. Nothing the carnal man does is by faith. Most importantly, the carnal man cannot repent, or believe the gospel.
The cross did away with, crucified the sin nature, all believers have a new nature with the old man being dead now, by the cross.
Correction: The cross does away with the sinful nature, but you are conflating the instrument itself with the good news which revolves around self sacrifice. The sacrificial system points to self sacrifice in general, and the sacrifice of Christ specifically. Yes, Christ's sacrifice does away with "the likeness of sinful flesh", but unless or until one is able to pick up their own cross and crucify the flesh themselves (Gal.5:24), they cannot receive the new birth. Again, I already provided you with examples from the Old Testament. You haven't addressed any of them yet.
QUOTE] All in Adam are born with the sin nature. All in Christ now (after the cross)
Again, Christ was slain from the foundations of the world (Heb.9:26;1Pet.1:20) for ALL men, not just those who were born after the historical event of Christ's death on a cross.
have the nature of God which is in Christ, Christ in you nature.
Your restrictions are unfounded. Christ himself points out that Abraham rejoiced in the coming of messiah.
Flesh is mind given to body, a body is only what is given to it, has no life of it's own.
Yes, Quite true! Now that "you" understand that, "you" just need to realize that "you" don't really exist. You are not who you think you are. This contradictory idea you have of yourself as a separate individual is nothing more than an abstract construction of the mind. This is an idea we all learn as we develop from infancy. Abstract constructions of the mind have no life of their own. This is not just the truth of scripture. Science agrees with this empirical fact as well.
I'm saying the birthing is Christ in you,
I agree.
impossible to happen in the OT because it took the cross to kill out the sin nature.
Impossible to happen for anyone who is incapable of self sacrifice as well. Again, Christ was slain from the foundation of the world which was considerably earlier than the Old Testament. Christ's sacrifice is the only sacrifice that actually removes sin, but the fact that it occurred after a born again believer received the gospel message is quite simply irrelevant. It matters not when one receives the gospel, and there is nothing preventing someone who lived before Christ from receiving the gospel message. Again, it doesn't just save those who lived after Christ was crucified, nor does the timing of Christ's sacrifice prevent one from receiving salvation simply because they lived prior to the crucifixion. This is your assertion, and I see nothing to substante it anywhere in scripture.
For an OT saint to be birthed they would need Christ them and they did not have Christ in them.
False. Paul himself points out that they had Christ leading them throughout the wilderness. The rock with overflowing water is Christ IN THEM. Paul explicitly points this out for our edification. He explicitly points out that they drank in Christ. They were sustained exclusively by Christ. Christ points out that one cannot rely upon God and Mammon. They relied EXCLUSIVELY upon God. Do you have to ask someone to provide you with a coin or currency to prove a point, or do you have some in your wallet?
The new creation is; Christ in you the hope of glory. Christ in you, the twain become one. You cannot make son's, son's are not created they are literally birthed, there absulutely must be a father invovled to bring about a birth.
Yep, and there's nothing preventing God from doing that anywhere throughout human history.
There is no fatherhood from God in the OT, there was no grace.
False. God's grace is spread abundantly, but more importantly, the gospel message was as well, and those who received in in gladness were saved and born again, and produced fruit. The grace and truth that existed in the Old Testament was manifested in the flesh of Christ in the New. In other words, Christ personifies the grace and truth of Almighty God. The only difference is that he is sinless, we're not. This doesn't prevent you or I or even righteous Abel from receiving the gospel. Christ's sacrifice is eternal, and his sacrifice reaches all the way back to Adam.
What we see is an angry OT God that you best obey, no fatherhood.
This is what you choose to see. What the saved born again believer in the Old Testament saw was his own sin, and the righteous judgment of God which convicted them, and allowed them to receive the precious gift of repentance. What you are missing out on is the glaring fact that they are ALL saved. If you don't remember being convicted by God, then you couldn't have received the gift of repentance, and can't be saved. Paul spells this out for us in his letters, and even points out that this is exactly what is going on in the Old Testament.
there is nothing in the written word that carries the weight of the in Christ message, not a single scripture of saints in the OT being in Christ, over 150 times times in the NT Paul has the believer in Christ
False. Look at Christ in the garden of Gethsemene, and you see the righteous judgement of God's wrath descending upon him. We see this throughout the Old Testament as well, but we also see repentance. It is a pervasive theme throughout the bible, and there can be no salvation without it. We see God's presence protecting His chosen people as they wandered through the wilderness, and into the Promised land.
God takes his people from bondage to sin, into the wilderness where he gives them his law. His presence with them prevents many from sinning under the immediate threat of death. This is what it means to live under the New Covenant. The new creature simply cannot sin. It is no different than placing a gun to your head and pulling the trigger. The wages of sin is death, but those who are given a new heart make their way into the Promised land. These are all illustrations of the reality of salvation. Paul points out that they are explicitly for our edification.
I can make the exact same argument you are with the arbitrary difference of saying that only those who looked forward to the cross are saved while those who lived afterwards missed the boat altogether. You snooze, you lose. I can assert that you were just simply unlucky enough to have been born after the fact rather than before. They could all see what their destiny was while you missed it. See how pointless it is to come up with these type of theories?
The fact that God's grace and truth were manifested in Christ doesn't negate God's ability to save anyone prior to or after that event. It doesn't negate the fact that the scriptures point out God's presence in the midst of his chosen people. This is probably the best translation of Christ's words in the new testament when he says, "the kingdom of God is in your midst" Luke 17:20-21 He couldn't have meant that it was within them because he was addressing the Pharisees who wanted to kill their king. They had only murder in their hearts.
Again, Paul calls upon us to crucify the flesh daily, and only those who have Christ living in, with, and through them can crucify the carnal man. The carnal man must wrestle with God just as Jacob did, but just because God chooses to save you doesn't mean he didn't choose to save each and every lost soul Christ came to save before he lived "in the likeness of sinful flesh".
