That is what you say - not Paul.Our basis for the bodily resurrection is due to now being being spiritually alive in Jesus, and not still spiritual dead in Adam!
In that passage Paul speaks of different kinds of "flesh" (man, animal, etc.) and points to us being resurrected with a body (but one that is spiritual, how it is we do not yet know).
You are taking a statement in one verse out of context to emphasize your opinion. That is abusing Scripture.
That is not in the Bible, but I understand it is what you believe.Adam when created was sinless in his humanity, nature as he was in the state Jesus was born in at Incarnation.... Both were sinless humanity, perfect flesh , but Adam sinned and experienced the effects of the fall, as we all do save for Jesus!
