I am going to go with you on this track about being eternal. I agree that all men will continue on eternally. Some to be with Jesus, some in torment. And it is the way we were created, because of the breath of God in each of us.I could say the same about you, and my case would stronger. But let us put grammar aside for a moment, look at it from a purely theoretical point of view. Did in Adam all die? They did! Was Adam immortal when he was in the garden of Eden? He was. Did he become mortal after Fall? He did: "for dust thou art, and unto dust shalt thou return" (Gen. 3:19). Was that the cause of all mankind becoming mortal, subject to death? It was. Will all mankind, without exception, become immortal again someday? They will. Is that biblical? Yes. What is the biblical word used for that immortality? It is called the resurrection. Is resurrection universal? It is. Will all mankind be resurrected someday without exception, never to die again? Yes. What is the cause of their resurrection? The Atonement of Jesus Christ: "I am the resurrection, and the life" (John 11:25). Had it not been for the Atonement, would anyone have been resurrected? Not one! Because of the Atonement of Jesus Christ, will everyone be resurrected? Yes! Is there anyone left out, forgotten about, who will not be resurrected? Not one! Was it because of the Atonement that all of this happens? Yes! Had it not been for the Atonement, would any of this happened? Not one! So there is a correct theological sense in which to say that "as in Adam all die, even so in Christ shall all be made alive" in a very literal, symmetrical sense; the first all being identical in meaning to the second all.
