There's this idea floating around that says Adam's flesh, when he was created, was not flesh of sin like his progeny. This idea claims that Adam's flesh changed or that his nature changed after he sinned.
Well if you don't know let me be the first to inform you. The Scripture NOWHERE says any such thing as that idea claims. If you can find it in Scripture please let me know. I'm sure that you won't cause I do my homework.
Anyway, the inspired apostle speaks the truth. Hear him.
Paul calls Adam the natural man made from dust and that the natural body, or earthy body(like Adam's) comes before the spiritual body by being raised from the dead.
42 So also is the resurrection of the dead. It is sown in corruption; it is raised in incorruption: 43 It is sown in dishonour; it is raised in glory: it is sown in weakness; it is raised in power: 44 It is sown a natural body; it is raised a spiritual body. There is a natural body, and there is a spiritual body. 45And so it is written, The first man Adam was made a living soul; the last Adam was made a quickening spirit. 46Howbeit that was not first which is spiritual, but that which is natural; and afterward that which is spiritual. 47The first man is of the earth, earthy: the second man is the Lord from heaven. 48As is the earthy, such are they also that are earthy: and as is the heavenly, such are they also that are heavenly. 49And as we have borne the image of the earthy, we shall also bear the image of the heavenly.
Now that's powerful truth! And it flies in the face of the deceiver who made up the idea that the natural man made from the earth, of whom still needs a change of nature, had a change of flesh or nature after he sinned.
