The entire period between the ascension and return of Christ is the millennium. Christ is ruling now over a spiritual kingdom that will be immediately raptured at His return, and the new heavens and earth will then be in place.
"Coming out of his mouth is a sharp sword with which to strike down the nations. “He will rule them with an iron scepter.”
Christ is not currently ruling the nations with an iron scepter.
"And I saw an angel coming down out of heaven, having the key to the Abyss and holding in his hand a great chain. He seized the dragon, that ancient serpent, who is the devil, or Satan, and bound him for a thousand years. He threw him into the Abyss, and locked and sealed it over him, to keep him from deceiving the nations anymore until the thousand years were ended."
The thousand years is a literal thousand years which according to the chronology of Revelation, takes place after God's wrath has been completed which will be carried out via the seals, trumpets and bowl judgments, where after the 7th bowl is poured out Christ returns to the earth physically and visually to end the age (Matt.24:30-31) which initiates the millennial kingdom. During that thousand years Satan is literally bound in the Abyss so that he cannot deceive the nations during that time. That said, Satan is by no means currently bound, as he is currently out and about in the world continuing to deceive the inhabitants of the earth.
"And I saw an angel standing in the sun, who cried in a loud voice to all the birds flying in midair, “Come, gather together for the great supper of God, so that you may eat the flesh of kings, generals, and the mighty, of horses and their riders, and the flesh of all people, free and slave, great and small.”
The above event where the angel calls all the birds to eat the flesh of those who will have been killed by the double-edged sword takes place as Christ is returning to the earth to end the age. Since the thousand years begins after this event, when did this ever take place? The answer is that, it hasn't! If thousand years had already started, the world would have witnessed this event.
This millennial kingdom’s temple is our bodies
1 Corinthians 6:19 Or do you not know that your body is a temple of the Holy Spirit within you, whom you have from God, and that you are not your own?
When Jesus came, he eliminated the need for a temple (building) being in a single location. Christians became the temple of God, a house for his Holy Spirit. Because of his blood that made us clean, we can now be considered pure and holy enough to have God’s Spirit live in us.
You are correct, we, believers in Christ which are made up of both Jew and Gentile, are the temple of God. However, prophesies regarding the unbelieving nation of Israel still must be fulfilled. The last seven years of the seventy sevens that was decreed upon Israel and Jerusalem must still be fulfilled.
"So when you see standing in the holy place ‘the abomination that causes desolation,’ spoken of through the prophet Daniel—let the reader understand—then let those who are in Judea flee to the mountains.
The ruler/antichrist must still set up that abomination in the holy place causing the desolation of Jerusalem/Judea when they flee out into the desert to that place prepared for them by God.
"For then there will be great distress, unequaled from the beginning of the world until now—and never to be equaled again. “If those days had not been cut short, no one would survive, but for the sake of the elect those days will be shortened."
By the time that seven years is over, if the time of God's wrath was allowed to go on any longer then the specified time, no one would be left alive on the earth. When has the world seen this time of great tribulation? The answer is never! This time of great tribulation is yet future and will take place after the church has been gathered. Following Christ return to the earth to end the age, the beast and the false prophet will be captured and thrown alive into the lake of fire. When has that happened?
"They came to life and reigned with Christ a thousand years. (The rest of the dead did not come to life until the thousand years were ended.) This is the first resurrection. Blessed and holy are those who share in the first resurrection. The second death has no power over them, but they will be priests of God and of Christ and will reign with him for a thousand years."
When did the resurrection take place and when have those resurrected reigned with Christ during that thousand years? According to your belief that we are currently living in the thousand years. Some of the characteristics of this time period is that prey and predator and their young will lie down together and during that time the lion will eat straw like the Ox. A young child will stick his hand in a vipers nest and not be hurt at all. The reason for this is because the scripture says:
"They will neither harm nor destroy on all My holy mountain, for the earth will be full of the knowledge of the LORD as the sea is full of water."
During that literal thousand years, peace will reign on the earth. And I don't have to tell you that the world has seen nothing like this whatsoever. And that because the thousand years is a future age which will take place after the seven years of God's tribulation, which will decimate the majority of the inhabitants of the earth and dismantle all human government.
Amillennialism is the position on eschatology that the “tribulation” period is 1st century history and that things will mostly continue as they are until Christ returns
Amillennialism, along with Preterism, are two of the most deceptive teachings on the planet. Below is the chronological order of end-time events leading up to the Lord's returns to the earth to end the age:
* The resurrection of the dead in Christ as well as those still living in Christ being changed and caught up with them
* The initiation of that last seven years that was decreed upon Israel and Jerusalem (Daniel 9:24-27)
* God's wrath via the seals, trumpets and bowl judgments take place during the entire seven years
* Jesus returns to the earth to end the age after the 7th bowl has been poured out
* The beast and the false prophet are thrown alive into the lake of fire
* Satan is thrown into the Abyss and sealed for a thousand years
* The great tribulation saints are resurrected
* Millennial kingdom (thousand years) begins, a time of the Lord's reign with complete peace on the earth
* When the literal thousand years are over, Satan will be released for one more deception
* Satan is then thrown into the lake of fire where the beast and the false prophet will have been thrown
* The great white throne judgment: The unrighteous dead throughout all of history will be judged
* Everyone's name not found in the book of life will be thrown into the lake of fire
* New heaven, new earth, new Jerusalem
* Eternity -------------------------------------------------------------------------------------------------------------------->
