Randy Alcorn answers the question, "How has the philosophy of Plato affected our view of Heaven?" Q&A about Heaven at The Way, A Jesus Church's (formerly Solid Rock Church) ministry to "twenty-somethings." See Randy's book Heaven for more information.

Bodies aren't shells for souls, they're part of who we are. Any afterlife view that denies bodily resurrection is unchristian.

God no more gives up on the Earth than He gives up on us. He is no more done with the Earth than He is done with us. God promises He will reverse the curse:

The physical resurrection of Jesus Christ is the cornerstone of redemption—both for mankind and for the earth. Indeed, without Christ’s resurrection and what it means—an eternal future for fully restored human beings dwelling on a fully restored Earth—there is no Christianity.

Therefore God will honor the work of his Son by raising your body from the dead, and you will use your body to glorify him forever and ever. That is why you have a body now. And that is why it will be raised imperishable.
