If you believe that Christ is the resurrection and life you believe He has changed the nature of death. Although you die temporally you do not die eternally. You are not dead in the materialist sense; you are only asleep. After you die temporally your body remains united to your living Head, Jesus Christ, and by virtue of Him it lives; and it is on the basis of this living union that you shall be raised again, body and soul, at the last day. Such is the life of Christ in you that you account yourself dead even now because you are crucified with Christ, and the life that you live in the flesh you live by faith in the Son of God who loved you and gave Himself for you.
