Revelation 11 comes long before Revelation 20, but it upholds the Millennium rather than the opposite. So let's look at your
specious argument:
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. And the four and twenty elders, which sat before God on their seats, fell upon their faces, and worshipped God, Saying, We give thee thanks, O Lord God Almighty, which art, and wast, and art to come; because thou hast taken to thee thy great power, and hast reigned.
This is merely a PROPHETIC STATEMENT. It is speaking of a future event as though it has been already fulfilled, since from God's perspective that is exactly the case. Now we will look at a similar (and corresponding) statement from Daniel's prophecy, which was given in approximately 600 BC and appeared to being fulfilled at that time, but speaking of a far distant event:
I saw in the night visions, and, behold, one like the Son of man [CHRIST] came with the clouds of heaven, and came to the Ancient of days, [GOD THE FATHER] and they brought him near before him. And there was given him dominion, and glory, and a kingdom, that all people, nations, and languages, should serve him: his dominion is an everlasting dominion, which shall not pass away, and his kingdom that which shall not be destroyed. (Dan 7:13,14)
Making such NONSENSICAL STATEMENTS does not help your credibility.
As noted above it is NOT what happens at the seventh trumpet, but
WHAT IS PROPHESIED at the 7th trumpet. So rather than address all your muddled conclusions, let's look at Rev 11:15-19 AS RELATED TO THE MILLENNIUM.
1. The kingdoms of this world are become the kingdoms of our Lord, and of his Christ...
From Daniel's prophecy above, it is clear that after the second coming of Christ, all earthly kingdoms will be abolished so that Christ set's up the Kingdom of God on earth.
There are multiple prophecies to support this, but we will take just on from another prophetic book:
Behold, a king shall reign in righteousness, and princes shall rule in judgment. (Isa 32:1) Who is this King who shall reign in righteousness? Is it not the Lord Jesus Christ at the Millennium? And in order to reign in righteousness, is it not imperative that all unrighteousness be abolished from the earth? And are not all the nations and kingdoms of this world presently unrighteous? So the only way that Christ can reign in righteousness is to bring every nation and kingdom to that state of righteousness which He requires.
2. ...and he shall reign for ever and ever.
What does this tell us? Does it not tell us that the Millennium is THE PRELUDE to the eternal Kingdom of God on earth?
3. ...because thou hast taken to thee thy great power, and hast reigned.
It should be evident to anyone with a little common sense that this was NOT FULFILLED within the time frame of Rev 11. Why? Because we have to arrive at Rev 19 and 20 to see this being fulfilled.
REVELATION 19
11 And I saw heaven opened, and behold a white horse; and he that sat upon him was called Faithful and True, and in righteousness he doth judge and make war.
12 His eyes were as a flame of fire, and on his head were many crowns; and he had a name written, that no man knew, but he himself.
13 And he was clothed with a vesture dipped in blood: and his name is called The Word of God.
14 And the armies which were in heaven followed him upon white horses, clothed in fine linen, white and clean.
15 And out of his mouth goeth a sharp sword, that with it he should smite the nations: and he shall rule them with a rod of iron: and he treadeth the winepress of the fierceness and wrath of Almighty God.
16 And he hath on his vesture and on his thigh a name written, KING OF KINGS, AND LORD OF LORDS.
17 And I saw an angel standing in the sun; and he cried with a loud voice, saying to all the fowls that fly in the midst of heaven, Come and gather yourselves together unto the supper of the great God;
18 That ye may eat the flesh of kings, and the flesh of captains, and the flesh of mighty men, and the flesh of horses, and of them that sit on them, and the flesh of all men, both free and bond, both small and great.
19 And I saw the beast, and the kings of the earth, and their armies, gathered together to make war against him that sat on the horse, and against his army.
20 And the beast was taken, and with him the false prophet that wrought miracles before him, with which he deceived them that had received the mark of the beast, and them that worshipped his image. These both were cast alive into a lake of fire burning with brimstone.
21 And the remnant were slain with the sword of him that sat upon the horse, which sword proceeded out of his mouth: and all the fowls were filled with their flesh.
REVELATION 20 [A (THE)THOUSAND YEARS REPEATED SIX TIMES IN SEVEN VERSES]
1 And I saw an angel come down from heaven, having the key of the bottomless pit and a great chain in his hand.
2 And he laid hold on the dragon, that old serpent, which is the Devil, and Satan, and bound him a thousand years,
3 And cast him into the bottomless pit, and shut him up, and set a seal upon him, that he should deceive the nations no more, till the thousand years should be fulfilled: and after that he must be loosed a little season.
4 And I saw thrones, and they sat upon them, and judgment was given unto them: and I saw the souls of them that were beheaded for the witness of Jesus, and for the word of God, and which had not worshipped the beast, neither his image, neither had received his mark upon their foreheads, or in their hands; and they lived and reigned with Christ a thousand years.
5 But the rest of the dead lived not again until the thousand years were finished. This is the first resurrection.
6 Blessed and holy is he that hath part in the first resurrection: on such the second death hath no power, but they shall be priests of God and of Christ, and shall reign with him a thousand years.
7 And when the thousand years are expired, Satan shall be loosed out of his prison,
8 And shall go out to deceive the nations which are in the four quarters of the earth, Gog and Magog, to gather them together to battle: the number of whom is as the sand of the sea.
9 And they went up on the breadth of the earth, and compassed the camp of the saints about, and the beloved city: and fire came down from God out of heaven, and devoured them.
I TRUST THAT AFTER THIS BIBLICAL REFUTATION OF AMILLENNIALISM, YOU WILL EITHER REPENT AND BELIEVE THIS WHOLEHEARTEDLY, OR SHUT UP RATHER THAN OPPOSE SCRIPTURE.
