If Christ kingdom was here now,satan would be bound in the pit,evil would not be here, and one fact beyond all facts is the fact that we would all be changed into our spiritual bodies.

Let's go over this again. Rev 20 does NOT state that ALL evil will be gone. That ALL of Satan's influence will be null and void. I mean...does it? Can you show me in Rev 20 where it says any of that?
I can show you in Rev 20 where it tells us rather specifically that Satan will be bound (a synonym for restricted by the way) against 'deceiving the nations'. Not 'doing all evil and harm against humanity'. Nope, "deceiving the nations". In fact, it tells us more. "Deceiving the nations to gather them to war"...war against whom? The saints. That would be us...the people of God.
So, basically Rev 20 is telling us Satan will be bound against wiping Christians off the face of the planet...or making a pretty good go of it by uniting all nations together against us. We're still here, are we not? Hmmm...that could make one think that Satan had not been able to do this yet, wouldn't it?
As far as 'we have to be in our spiritual bodies' to be in the Millennium...where does it state this? I see in scripture that when Christ RETURNS we receive our spiritual bodies, most certianly. There is no squeezing around that. The problem then comes when someone tries to determine if the bible speaks of a Kingdom beyond Christ's return, or before it? Does the bible give us leave to place anything but eternity and no death after Christ's return?
I would say that scripture paints quite clearly that the Kingdom is NOW. That the Kingdom will be handed over to the Father AT Christ's return, a finishing, not a beginning. It tells us that AT Christ's return and our gaining our spiritual bodies, death itself will be ultimately defeated, which begs the question; how on earth can a Millennial reign come after that? Aren't people supposed to still die? Sure, they live longer, but death and sin, and Satan are by no means 'ultimately' defeated. And yet, scripture tells me that AT Christ's return, those things are, indeed, defeated.
To be honest, I see absolutely no evidence that there could be, let alone might be, a period of time after Christ's return, where people might exist in both normal and glorified bodies, in a state of nature that is still subjected to the curse. Peter tells us that AT Christs return the whole cosmos will be renewed! Jesus himself tells us that AT his return everyone alive will be judged. That puts every living soul in hell or in the new heavens or earth, basically.
He hands over the kingdom to the Father at the end of that Day,ie,the millennium ,ie the Day of the Lord!!!
I Corinthians 15:24 "Then cometh the end, when He shall have delivered up the kingdom to God, even the Father; when He shall have put down all rule and all authority and power."
That might hold weight IF you could, in any way, prove that 'the end' was 'the millennium'.
But each in his own order: Christ the firstfruits, then at his coming those who belong to Christ. Then comes the end, when he delivers the kingdom to God the Father after destroying every rule and every authority and power. For he must reign until he has put all his enemies under his feet. The last enemy to be destroyed is death. -1 Corinthians 15:23–26
This passage tells us that the Kingdom...the Kingdom we are currently IN, will come to an end "at his coming". It is at this time "when he delivers it to his Father AFTER destroying every rule and authority and power". And you know what the last power was? It was the one he took out AT his return....it was death. And AT it's final defeat, an earthly Millennium became impossible.
Also, there is nothing in this passage, or below it, where it speaks of the rapture and the 'death of death', to suggest that this is the beginning of 'another Kingdom'. This is essentially what you are suggesting. There is the Kingdom of heaven which is now. That is what Christ delivers over to the Father at his coming, at 'the end'. Then you suggest that there comes the "Millennial Kingdom"...a place where some people dwell in heavenly, spiritual bodies, but some live on in earthly bodies...and these people will 'populate' the Millennial Kingdom. They will also be subject to sin and death if they rebel against King Jesus. Lets ignore the fact that the bible never speaks of such a 'intermediate Kingdom' between this age and the eternal age...a Kingdom between this one, the one he "hands over to the Father" and the Eternal one where death is no more. Let's focus on the complete ridiculousness of two natures dwelling side by side at the same time in a manner the bible doesn't talk about and makes zero sense. It makes no sense because the bible won't let ANYONE escape judgement at Christ's coming...ain't nobody getting through THAT coming with a natural body. And then to say that sin and death will persist beyond the return of Christ? Why's he even coming then? What's the point of all the passages that point towards HIS ARRIVAL being the ultimate end to those very things? Then let's look at the fact that at the end of this 'intermediate kingdom' we have what amounts to another rebellion and armeggedon. Wasn't one enough? Why on earth would God have what appears to be a "history in mini" set up between the ages? Complete with a temple and sacrifices, which are a complete blasphemy against the risen Lord who died for us, by the way.
Any, and every way you look at it, having an earthly Millennium does NOT add up with what scripture tells us about what happens and when it happens AT Jesus' return.
At the very end of the Millennium age, the Son will deliver His Kingdom up to the Father. At the time of the Judgment God will put an end to all the rule and all power and authority that Satan will have on this world, or anywhere. That is when God will send Satan and all his realm and all evil and those that chose to follow him into the lake of fire.
That's not what it says! The passage is talking about the Rapture! You cannot divorce the two, pick and choose which parts you want to shove 1000 years apart. Christ returns to us, gathers us up, gives us new, spiritual bodies...and defeats death! It is this defeat that puts the 'last enemy' under his feet, and allows him to hand over the Kingdom. And that, my friend, IS the end. It's a wrap. And, death being done, as I said, makes an eartly Millennium, impossible.
Revelation 11:15 "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."
Flesh and blood cannot enter that kingdom,period!!!!!!!
Well, see, now you have me confused. Because most people supporting an earthly millennium posit that there have to be at least SOME 'normies'. If the whole Kingdom is filled with saved people with glorified bodies....aren't we just calling it heaven at that point?? Especially if we start looping in Peter with him saying that the whole cosmos will be renewed at Christ's second advent.
So...what exactly ARE you saying the Millennium will be?
