1 Corinthians 15:24 - Matthew Poole's English Annotations on the Holy Bible

Then cometh the end; the end of all the miseries and afflictions which believers meet with in this life, or the end of all our preaching and ministry, the end of the world, or the end of man; or rather, (as the next words seem to interpret it), the end of that mediatory kingdom of Christ, which he now administereth instead of his Father, and shall manage to the end of the world. When he shall have delivered up the kingdom to God, even the Father: Christ shall then deliver up those keys of life, and hell, and death to his Father, yet shall not Christ's kingdom cease (for the prophet saith, Isaiah 9:7, that of it there shall be no end): Christ's essential kingdom, which is his dominion, which he hath and exerciseth over all created beings, together with his Father, and the Holy Spirit, (all being but one Divine essence), that shall hold and abide for ever; but his mediatory kingdom, by which he ruleth over his church in the midst of his enemies, that shall cease, and be delivered up unto the Father. So that Christ's delivering up the kingdom to his Father, proveth no inferiority of Christ to his Father, more than his Father's committing that mediatory kingdom to him can prove his Father's not reigning, or inferiority to him, which it certainly doth not. It signifieth only the ceasing of that dispensation, or Christ's exercise of his mediatory kingdom on earth, in the rule and government of the church, and subduing his and his people's enemies. When he shall have put down all rule and all authority and power; then shall all rule and authority of kings and princes of the earth cease, and all the ministration of good angels, and power of evil angels; so shall all ministrations and governments in the church militant here on earth, and all those that are the enemies of the church shall be subdued and brought under.
