We would agree that Jesus will be turning over His KIngdom to the Father, but do not agree that Jesus will have put down all of His enemies apart from that being made literally true during His reign here upon the restored earth.He is ruling over them now. He is putting them down now. One by one they are under His feet! 1 Corinthians 15:22-24, stating, “For as in Adam all die, even so in Christ shall all be made alive. But every man in his own order: Christ the firstfruits; afterward they that are Christ's at his Coming. Then (or eita or thereupon) cometh the end, when he shall have delivered up the kingdom to God, even the Father; when he shall have put down (or katargeésee or abolished) all rule and all authority and power.”
1 Corinthians 15:22-24 tells us that “all rule and all authority and power” are finally “put down” or katargeésee or abolished at the “Coming” or parousia of the Lord, which is, as we have established, confirmed in the next sentence as “the end.” The kingdom of God is finally and eternally presented “up,” whereas the kingdom of darkness is finally and eternally “put down.” It is this all-consummating last day that ushers in the end (or completion) of all things.
Paul reinforce his point in regard to the concluding nature of Christ’s return, and how it spells the termination of death and rebellion, 1 Corinthians 15:25-28, saying: “For [Gr. gar or seeing] he must reign, till he hath put all enemies under his feet. The last enemy that shall be destroyed is death. For ‘he hath put’ (aorist active indicative) all things under his feet. But when he saith, all things are put under him, it is manifest that he is excepted, which did put all things under him. And when all things shall be [Gr. hupotageé] subdued (or subordinated) unto him (speaking of the Second Coming), then shall the Son also himself be subject unto him that put all things under him, that God may be all in all” (1 Corinthians 15:25-28).
After telling us that Christ’s Coming sees the termination of the wicked and their evil operations, the writer tells us that Christ’s reign over His enemies must continue until this climactic point. Whilst “all power” is now assuredly given unto Christ “in heaven and in earth” (Matthew 28:18) through His life, death and resurrection, and whilst through this victorious work “he hath put all things under his feet” in a sovereign manner, we have not yet seen the final subduing of wickedness. This comes at the Second Coming of the Lord.
Paul is simply reinforcing the thought that he just stated about the climactic Coming of Christ. It is the time “when he shall have put down (or abolished) all rule and all authority and power.” 1 Corinthians 15 verses 24 and 28 repeat the same all-consummating truth.
