Who besides Adam was created on the 6th day? I'm not confused about what the Scriptures say. I'm confused as to why you believe "many" people were created on the 6th day when the Bible only says that Man, singular, was created on the 6th day?
Nobody here is arguing the Virgin Birth doctrine.
Whatever language you use, we do have to die to our corrupted flesh, which refers to our current physical stature being infected with a Sin Nature. We "die to it" simply by ensuring all that we do is done in cooperation with the Spirit of Christ. What we are doing is dying to our independent spirit, making sure our physical beings conform to the will of God, and not to our own independent will.
Being that as it may, Scripture makes a big deal out of the difference between mortality and immortality. Our hope is in putting on the new immortal, glorified bodies that Christ has promised us in the resurrection. Our present bodies have a Sin Nature, which is the very reason we are mortal and must die physically.
I don't agree with your terms. Being "immortal," in the biblical sense, means that we can no longer sin and die. That is what "immortal" means.
You may be right that our original bodies were not intended to die, simply because God did not intend for us to sin. But He did give us that choice, which is why bodies that would not have died did die.
But Paul argued that our current bodies, whether in the original form of Adam or in our current sin-cursed form, are a "seed." That is, they were not intended to be permanent, even if they were not intended to die.
As sinful people our bodies do die, just as a seed in the ground metaphorically "dies." But before the Fall, Paul may have characterized these bodies differently, as bodies that shift-change once we partake of the Tree of Life. Worth a thought?
You seem to use the word "immortal" for "eternal." I believe all men are eternal, but not all men are immortal. So the terms "immortal" and "eternal" are not always interchangeable, and certainly not in this context, as I see it.
I don't know what you think I believe? Sin is not removed spiritually until we become sinless, which certainly is not where we're at today! Our legal judgment has been removed, but now "grace" is the thing that controls the process, so that we partake of God's life while at the same time suffering the setbacks and obstacles imposed by our Sin Nature.
Don't really understand your argument here? If the sinful mind cannot perceive God then how could anybody be saved? They certainly have the ability to receive revelation from God so that they can abandon their sinful mind in favor of a renewed mind! The only mind that cannot receive revelation is the stubborn, recalcitrant mind of the flesh.
Adam remained in the same body, according to the Scriptures--he just changed. Having received a Sin Nature his body became susceptible to all kinds of trouble, disease, and death. But it was the original body, now sickened by the affects of the Sin Nature.
It was the mind, as you say, that was affected by the Sin Nature, turning human decisions into a process that begins with self-autonomy, or independent judgment from God's judgment. But we are able to consider God's point of view and His wish for us, and we can then turn our mind away from independent judgment to consult the Lord and His wisdom.
Sorry, too many interruptions right now....
