I just thought of something for everyone that believes the resurrection is not going to be physical.
Jesus is going to have every enemy put under his feet when the ends takes place. And The Last Enemy is death. Paul said, in 1st Corinthians chapter 15, that resurrection occurs when death is put under his feet.
If the resurrection leaves our physical bodies behind and dead, and out from within those physical bodies comes an invisible spiritual body that separate and distinct from the dead body, then we've got a big problem. Paul distinctly said that Resurrection can only occur with something if it has first died, after having lived previously.
1 Cor 15: 36 Thou fool, that which thou sowest is not quickened, except it die:
Resurrection means something is given life the second time, or resurged. When did the spiritual body that's invisible and comes out of the Dead physical body ever die before it came out? According to what I can assume in the non-physical resurrection doctrine, they believe that the spiritual, invisible body that's inside of us was always alive and never did die. When the resurrection occurs, what Paul said must occur is that something that did die is in a state of death, and comes alive again a second time.
If the spiritual body had not previously lived and died, then death is not defeated in that sort of rising. Death can only be defeated when it killed something, and that something is affected while being dead and then made alive again to never die any more.
So, the non-physical resurrection doctrine that says that which dies stays dead, does not answer the need for resurrection to defeat death. The way that the last enemy of death is put under Jesus' feet is by the way of the resurrection bringing a second life that is immortal to that which death had slain.
If the only body that dies is left to remain dead, while another distinct and separate body rises instead, then death was not in any way defeated.
