Yes, Brother, it is very hard to understand and to explain it, and I agree with you "how (could) this makes Michael the child born who is to rule all the nations with an iron scepter? It is hard to understand that because if based in theories that have been spread in this last times or last days, by them we can not see how the TRUE revelation makes sense. It's very difficult for us in the midst of so much confusion and apostasies to understand or to know what is the TRUE revelation and interpretation of this God's mystery.
The Word of God reveals that : (I will try to describe it)
1Thes.4:v.16- "The Lord himself shall descend from heaven with a shout, with the VOICE of the archangel-he is Michael-,and with the trump of God-the God's trump is with Michael- and the dead in Christ shall rise first yes (Dan.12:v.1-3), in fulfiment was written in the Word of God by Daniel. Actually Michael Judges and makes War-Revelation 12:v.7 and 16:v.13-16. After the battle or ending the battle, Michael will lay hold on the Dragon, that old serpent, which is the Devil, and Satan, and will bind him a thousand years, and will cast him into the bottomless pit, he will shut him up and will set a seal upon him, that the Devil deceives the nations no more. Rev.20:v.1-3.
THE BIRTH OF MICHAEL
We have to understand that in order to do his works in these last TIMES or last DAYS, Michael would first have to be born, I would say it is obvious, and grow, and develop to the age of performing his work according to what God had determined by Scriptures from the Old to the New Testament. By the way, as was exactly the case with John the Baptist for example, and much deeper, the birth of Jesus, the Word became flesh, which is far superior to angels, archangels, cherubim, in short, Jesus is only below God the Father in the heavenly hierarchy, but had to be born here to do His work according to the Scriptures. It's no different with Michael, of course.
Again: How could Michael stand up and make war and judge if he were not born first, just as Jesus and John the Baptist were born? Impossible of course. You see, it's very difficult in the midst of so much confusion to speak of the true revelation that God's Word brings unto us. But who is going to believe the true revelation that is within everyone's reach, living in this hostile environment full of speculation, and presumption, and conjectures, and apostasies, and cunningly devised fables, and so on? This end-of-day moment and end of the second covenant, is very complicated to understand because the earth is infested with tares.
Remember and consider that :
1 - The first coming of the LORD was with the VOICE that cried in the wilderness -John the Baptist- who was born by prophecy, that is by the power of the Word of God, for his mother was old, sterile, and unable to bear children, and his father Zachariah was old too. But the Word is God, so what is written fulfil literally by the Power of the written Word-the Word is God-.
2 - And now, the Lord will descend with the VOICE of the archangel, yes, with the VOICE of the archangel Michael - his VOICE is a trumpet and is a message, the God's trump is with Michael. The message is a trumpet, the problem is whether the voice or the message of the messenger is believed by the listeners. If the trumpet give an uncertain sound, who shall prepare himself to the battle? What battle? The battle is described in Rev.12:v.7 and 16:v.13-16 and will culminate with the prison of Satan into the bottomless pit.
Michael Judges and makes War; he will rescue them which are found written in the book of the Lord, but how? By a trumpet, by a powerful message, evidently, so powerful that there will be resurrection of the dead-Hallelujaaaah"-, some to everlasting life, and some to shame and everlasting contempt. And the environment in the earth will be of great distress such as never occurred since there was nation until THIS time, this is already running because this millennium belongs no more to the men, but to the LORD exclusively.
We see also Michael sounds the trumpet even now in the beginning of the first century of the seventh and last millennium, the millennium of Christ, or seventh and last Day, the Lord's Day, for this millennium belongs to the LORD exclusively, no more to the men. And the trumpet of Michael sounds in accord the prophecy as is written in 1 Thes. 4:v.16: "The Lord himself shall descend from heaven with a shout, with the voice of the archangel - Michael -, and with the trump of God: and the dead in Christ shall rise first-Dan.12:v.1-3. Its it.
About God's trump that must sound among us through the archangel Michael it is the seventh trump: Rev.11:v.15 - And the seventh angel sounded; and there were great voices in heaven, saying, The kingdoms of THIS WORLD ARE BECOME the kingdoms of our Lord, and of His Christ; and he shall reign for ever and ever. Michael will lay hold on the Dragon, that old serpent, which is the Devil, and Satan, and will bind him a thousand years, and will cast him into the bottomless pit, he will shut him up and will set a seal upon him, that the Devil deceives the nations no more. Rev.20:v.1-3.
Rev. 2:v. 17 - He that hath an ear, let him hear what the Spirit saith unto the Churches; To him that overcometh will I give to eat of the hidden manna...
that's Psalm 2:7-9, which is Christ, is it not?
The fact is that Jesus and Michael are very similar, it because Michael does not speak of himself; but whatsoever he heard from God he speaks, actually he received of JESUS and takes of Him, and he does not speak of himself, in other words, he has no message of his own, but the one he received from the Lord to speak in the churches. Revelation 1:v.12-13. This mystery is very deeper.
Revelation 5:v.9-10
9 And they sung a new song, saying, Thou art worthy to take the book, and to open the seals thereof: for thou wast slain, and hast redeemed us to God by thy blood out of every kindred, and tongue, and people, and nation;
10 And hast made us unto our God kings and priests: and we shall reign on the earth-Revelation 11:v.15.
In Christ JESUS, King of kings (made by Him) and LORD of lords
