What must Christ reign until, and what is the last enemy destroyed?
Christ must reign until He has put all enemies under His feet, and the last enemy to be destroyed is death. Scripture identifies death as the final enemy, which entered when Adam sinned, and Christ’s reign continues until every enemy is defeated.
Les explains from 1 Corinthians 15:25-27 that Paul is continuing the line of thinking that Christ will be all in all, King of Kings, and will reign and rule until everything has finally been defeated, even death itself. Death came when Adam sinned. Verse 25 says Christ must reign until He has put all enemies under His feet, and the last enemy destroyed is death. Verse 27 adds that all things are put under Him. Les also notes that this includes His ruling and reigning during the thousand years of His Kingdom rule, while the rest of the Godhead—God the Father and God the Spirit—remains in the background, because God is the triune Spirit Godhead.
For he must reign, till he hath put all enemies under his feet.
The last enemy that shall be destroyed is death.
