Passage
For he must reign until he put all enemies under his feet.
For he must reign until he put all enemies under his feet.
1 Corinthians 15:23 But each in his own rank: [the] first-fruits, Christ; then those that are the Christ's at his coming.
1 Corinthians 15:24 Then the end, when he gives up the kingdom to him [who is] God and Father; when he shall have annulled all rule and all authority and power.
1 Corinthians 15:25 For he must reign until he put all enemies under his feet.
1 Corinthians 15:26 [The] last enemy [that] is annulled [is] death.
1 Corinthians 15:27 For he has put all things in subjection under his feet. But when he says that all things are put in subjection, [it is] evident that [it is] except him who put all things in subjection to him.
The verse centers on "must", "reign", "until", "enemies", "under", and "feet". It is saying that the verse draws attention to "must" and "reign", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 24's "Then the end when he gives up..." into verse 26's "The last enemy that is annulled is...", so "must" and "reign" belong inside that flow. In 1 Corinthians context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "must" and "reign" with trust shaped by these words, not by a vague optimism outside the passage.
