What is the 'end' that comes in 1 Corinthians 15:24?
The 'end' in 1 Corinthians 15:24 is the conclusion of time as we know it, human history, when Christ delivers the Kingdom up to God the Father. It comes after He has put down all rule, authority, and power and reigns until every enemy is placed under His feet.
Les explains that "then cometh the end" refers to time as we know it—human history—when Christ shall have delivered up the Kingdom to God, even the Father. This occurs when He shall have put down all rule, authority, and power, for He must reign until He has put all enemies under His feet. Les connects this to Psalm 110:1, where God the Father speaks to God the Son: "Sit thou at my right hand, until I make thy enemies thy footstool." The enemies made Christ's footstool are all the forces of opposition.
Then cometh the end, when he shall have delivered up the kingdom to God, even the Father; when he shall have put down all rule and all authority and power.
