This is an unsubstantiated claim. The Bible teaches us that all things will be subjected to the Son, not only in this world, but also, the world to come. And none of the angels (including Michael) wasn't chosen.
Hebrews 2:5 It is not to angels that he has subjected the world to come, about which we are speaking.
1 Peter 3:22 who has gone into heaven and is at God’s right hand—with angels, authorities and powers in submission to him.
Ephesians 1:21 far above all rule and authority, power and dominion, and every name that is invoked, not only in the present age but also in the one to come.
There is no proof that Jesus Christ is the archangel, Michael. He is only mentioned five times in the Bible (Daniel 10:13, 21, 12:1, Jude 9, Revelation 12:7), and yet never do these verses indicate that he is to be equated with pre-existence, incarnation, exaltation, and the second coming of Christ (Hebrews 2:9, Philippians 2:9-11, Ephesians 1:20-23, 1 Peter 3:22, Revelations 5:11-14).
Michael is only one out of many "chief princes" from a group of them.
Daniel 10:13 But the prince of the Persian kingdom resisted me twenty-one days. Then Michael, one of the chief princes, came to help me, because I was detained there with the king of Persia.
The word "all" includes Michael too. Common sense tells us that Jesus Christ didn't worship himself if he was only an angel.
Hebrews 1:6 And again, when God brings his firstborn into the world, he says, “Let all God’s angels worship him.”
As a matter of fact, Jesus Christ rebukes the devil for not worshipping him as the LORD. And Michael, on the other hand, had to invoke the LORD to rebuke the devil.
Matthew 4:10-11 Jesus said to him, “Away from me, Satan! For it is written: ‘Worship the Lord your God, and serve him only.’ Then the devil left him, and angels came and attended him.
Jude 1:9 But even the archangel Michael, when he was disputing with the devil about the body of Moses, did not himself dare to condemn him for slander but said, “The Lord rebuke you!”
Jesus Christ is the judge. And one day we will judge angels but don't abuse that authority.
1 Corinthians 6:3 Do you not know that we will judge angels? How much more the things of this life!
2 Peter 2:11 yet even angels, although they are stronger and more powerful, do not heap abuse on such beings when bringing judgment on them from the Lord.
The real identity of Jesus Christ is the LORD. Would you like to publicly confess "Jesus is LORD" in this thread? I will assume that you will ignore everything I said and carry on like nothing never happen.
1 Corinthians 12:3 Therefore I want you to know that no one who is speaking by the Spirit of God says, “Jesus be cursed,” and no one can say, “Jesus is Lord,” except by the Holy Spirit.
Matthew 10:32-33 32 “Whoever acknowledges me before others, I will also acknowledge before my Father in heaven. But whoever disowns me before others, I will disown before my Father in heaven. (John 15:23-24, Luke 10:16, 1 John 2:22).
