I do not share this take. It seems to me that Pentecost in Acts 2 is a more likely account as well as those that would be alive at Jesus' coming on the clouds in the 1st century for his called ones.
Not exactly. In Rev 20, it says the martyred saints would reign with Jesus for 1000 years. It doesn't in any way limit the time of Jesus' reign nor does it tell us the precise locale.
AT this point, a new Heaven and a new Earth are very likely in play, and though I capitalized both (forgive my punctuation), the translators may very well have meant new land and skies when using those terms. In the age to come who can say what and where that land and sky will be?
Well, Jesus said it they would see the kingdom coming.
And he said unto them, V
erily I say unto you, That there be some of them that stand here, which shall not taste of death, till they have seen the kingdom of God come with power.
2
And after six days Jesus taketh with him Peter, and James, and John, and leadeth them up into an high mountain apart by themselves: and he was transfigured before them.
3 And his raiment became shining, exceeding white as snow; so as no fuller on earth can white them.
4 And there appeared unto them Elias with Moses: and they were talking with Jesus.
5 And Peter answered and said to Jesus, Master, it is good for us to be here: and let us make three tabernacles; one for thee, and one for Moses, and one for Elias.
6 For he wist not what to say; for they were sore afraid.
7 And there was a cloud that overshadowed them: and a voice came out of the cloud, saying, This is my beloved Son: hear him.
8 And suddenly, when they had looked round about, they saw no man any more, save Jesus only with themselves.
9 And as they came down from the mountain, he charged them that they should tell no man what things they had seen, till the Son of man were risen from the dead.
(Mk. 9:1-9 KJV)
Mathew ties the two together. And as I said, Peter recounts the event as the power and coming of Christ.
No, the passage doesn't expressly state that Christ will reign for a thousand years. However, Paul says that Christ will reign until all enemies are put under Jesus. In Rev 20 we see the Devil is bound for a thousand years then released for a short season to tempt the nations, He is then thrown into the Lake of Fire along with death and Hades. Paul says that the last enemy is death. So it's destroyed at the end of the thousand years. At this point all enemies have been put under Christ. Paul said Christ must reign until all enemies are put under Him.
We do know what the land is. Peter said that Christ must remain in Heaven until the rest restitution of all things. The creation will be restored. Paul said that the creation awaits the manifestation of the sons of God. We know it will be the same as before because, one, it is a restoration, and two, God had promised to give to Abraham all the land that he could see, however, he never received it.
