Note the CONTRAST between first Adam who is the ANTITHESIS of the second "Adam".
1Co 15:44
It is sown a natural body; it is raised a spiritual body. There is a natural body, and there is a spiritual body.
1Co 15:45
And so it is written, The first man Adam was made a living soul; the last Adam was made a quickening spirit.
1Co 15:46
¶
Howbeit that was not first which is spiritual, but that which is natural; and afterward that which is spiritual.
1Co 15:47
The first man is of the earth, earthy: the second man is the Lord from heaven.
1Co 15:48
As is the earthy, such are they also that are earthy: and as is the heavenly, such are they also that are heavenly.
1Co 15:49
And as we have borne the image of the earthy, we shall also bear the image of the heavenly.
Notice verse 46 which says boldly, that the first Adam was earthy or natural, not spiritual.
Daqq, I just might get a different hobby if you cannot see that Adam never was spiritual.
Paul uses the very word "antithesis" (ἀντίθεσις), in 1Tim 6:20, but does not use it anywhere else, including and especially not anywhere concerning Adam. One of the reasons why is because you do not "proclaim the end from the beginning" by revealing the "antithesis" but rather the "thesis", (Isa 40:21, Isa 41:4, Isa 41:26, Isa 45:21, Isa 46:9-10, Isa 48:3,5,16). A true "antithesis" would be someone like Qain or Barabbas. Moreover, you apparently do not understand what Paul is truly saying in what you quote: for he is telling you that you start out as the carnal man and must be converted, which is the same thing I am saying: it does not concern two different people but rather your "old man" and your "new man" in (the Testimony of) Messiah. Moreover you are ignoring everything else that has already been said throughout this entire thread. There are now four pages of evidence from the scripture which refute your position. I cannot force you to read so I suppose, since we will just have to agree to disagree, that you should find another thread or start your own.
