The last enemy to be destroyed is death. (1 Corinthians 15:26)
Death has an expiration date, for it is the last enemy to be destroyed. After that, there are no more enemies of God. No beings at enmity with God. Anywhere. After death is destroyed, there is only life. For death is nothing more than the absence of life, and where death itself has been put to death, there is no longer any impediment to life or any lack of life. Paul continues:
For he “has put everything under his feet.” Now when it says that “everything” has been put under him, it is clear that this does not include God himself, who put everything under Christ. When he has done this, then the Son himself will be made subject to him who put everything under him, so that God may be all in all. (1 Corinthians 15:27-28)When death is finally eliminated, all that exists, everything that has being, everything God has created, will have been made subject to Christ, brought into alignment with Christ, put in order under him. And Christ himself will be made subject to God — not in regard to the eternal and internal unity of the Trinity, but in the economy of our salvation.
And God will be “all in all.”
