Christ's reign will and must continue until every enemy has been conquered, and the last enemy that shall be destroyed is death. For the rule and authority over all things has been given to Christ by His Father. But in that quotation, "All things are put under Him," it is self-evident that God, who reduced everything to subjection, is not included. When Christ has finally won the battle against all His enemies, then shall the Son acknowledge Himself subject to God the Father, who gave the Son power over all things, that God may be utterly supreme, that He may be everything to everyone. (I Corinthians 15:25-28)
If this quotation does not square with your Bible, do not be alarmed. It is an amplification of these verses pieced together from the Phillips, King James, Taylor, Moffatt, and Norlie translations. The Father is drawing the entire creation into a state where everybody and everything acknowledge Him as God. When this occurs, division, confusion, and warfare will not exist because all, everything, is at one with our Creator.
Our acceptance of the sacrifice of Jesus Christ, repentance from dead works and receiving of God's Holy Spirit are the first major steps for each of us in seeking to become one with the Father. The next major step is the return of Jesus Christ, when we will inherit the Kingdom of God after the resurrection from the dead. The "all in all" of verse 28 is the very end point of the gospel.
Though I Corinthians 15:28 may appear to be something that happens in the distant future, the process has already begun in us. Understanding this as a reality is vital to our spiritual well-being. If we do not consider it to be real, we may be lured into neglecting our summons to this glorious destiny by letting ourselves follow distractions or grow irresponsible.

All in All
These verses conclusively reveal that others will be called besides us, until Christ defeats all enemies of God's rule. Because every person who has conformed to the image of Satan is an enemy, God will eventually call all of mankind and confront each one about who their sovereign is! As Satan has deceived "the whole world" (Revelation 12:9), so in His time will God call the whole world.
