It must remain desolate 1,000 years - because that's how long the separation is between the two resurrections.
We know this because the redeemed "lived and reigned with Christ 1,000 years" in the place He went to prepare for them WHICH IS NOT DOWN HERE, BUT UP THERE before returning for them in the Second Coming. What verses are you using to arrive at a conclusion different from this?
Zechariah 14. Isaiah 65. Revelation 20. In Matthew 25:31, Jesus is on the earth sitting on a throne in Jerusalem.
"When the Son of man shall come in his glory, and all the holy angels with him, then shall he sit upon the throne of his glory: And before him shall be gathered all nations: and he shall separate them one from another, as a shepherd divideth his sheep from the goats:"
Jesus is not waiting for the Second Coming to sit on a throne next to God in the heavenly. He has been in authority there, since the Cross. So the point in Matthew 25 is a throne on the earth, not in heaven. This throne and rule is in effect from the 6th Seal to the 7th Trumpet, when it will be declared that all the wicked have been removed from all nations, and now all nations belong to Christ the King as their only Sovereign. When the 7th Trumpet stops sounding, the millennium starts. Jesus keeps reigning over all the nations for a thousand years.
Matthew 13:36-42 also points out the final harvest via the 7 Thunders is on the earth.
"Then Jesus sent the multitude away, and went into the house: and his disciples came unto him, saying, Declare unto us the parable of the tares of the field. He answered and said unto them, He that soweth the good seed is the Son of man; The field is the world; the good seed are the children of the kingdom; but the tares are the children of the wicked one; The enemy that sowed them is the devil; the harvest is the end of the world; and the reapers are the angels. As therefore the tares are gathered and burned in the fire; so shall it be in the end of this world. The Son of man shall send forth his angels, and they shall gather out of his kingdom all things that offend, and them which do iniquity; And shall cast them into a furnace of fire: there shall be wailing and gnashing of teeth."
Once again, Jesus as King is the one going around talking to people on the earth. That is how seed is sown. Going out and meeting people face to face. Once the seed is sown and taken root, God knows who is redeemed and who is now a child of Satan. Like the sheep and goats were separated and removed from the earth, so will the wheat and the tares be removed by the angels on the earth. So why after cleaning up all the mess, setting up a throne, removing people to their eternal destinations, would Jesus as King not continue to rule till all of creation is made subject? 1 Corinthians 15:25-28
"For he must reign, till he hath put all enemies under his feet. The last enemy that shall be destroyed is death. For he hath put all things under his feet. But when he saith all things are put under him, it is manifest that he is excepted, which did put all things under him. And when all things shall be subdued unto him, then shall the Son also himself be subject unto him that put all things under him, that God may be all in all."
The tribulation or final harvest is God restoring the earth to pre-adamic conditions prior to Adam's disobedience. That was the point of that chapter.
"For as in Adam all die, even so in Christ shall all be made alive."
All covers more than just humanity. Being made alive covers more than humanity's redemption. The whole of creation is under the bondage of sin and death. Ruling and reigning is with Christ the King on the earth. Subduing the earth was established in Genesis 1:28.
"And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth, and
subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth."
Heaven does not need to be brought under subjection. The earth is what is being filled and completed, ready to be handed back to God at the end of the Millennium.
No one seems to grasp that when Jesus ascended to heaven in Acts 1, that as God he entered eternity and was always Jesus both Christ and King. The place prepared was written about in Genesis 1. Paradise was started in Genesis 2. The Lamb slain from the foundation of the world, was the Word.
You all teach a pre-incarnate Jesus, that had fake wounds already in place, no? Do you not think that Jesus sat and talked with Abraham? This is what Jesus told them:
"Your father Abraham rejoiced to see my day: and he saw it, and was glad. Then said the Jews unto him, Thou art not yet fifty years old, and hast thou seen Abraham? Jesus said unto them, Verily, verily, I say unto you, Before Abraham was, I am."
Jesus knew what would happen when He ascended back to the Father after His resurrection. That verse shows that Jesus always is. If you accept some pre-incarnate made up theology, why reject the real thing? Abraham walked with Jesus and saw the scars in His hands and feet, and the spear wound in His side. Abraham understood the death, burial, and resurrection. He was able to inform Isaac that if he died, God would resurrect him from the dead, because one day, one of his descendants would be God in human flesh. Abraham saw the time Jesus spent on the earth in the first century, because he saw the resurrected Jesus. Abraham saw the day of Jesus because Jesus showed him that day, when he visited Abraham in his tent. Not some pre-incarnate apparition.
Jesus was always preparing a place. Because Jesus always is, even though when he said those words, He had only been born, and baptized. He had yet to die on the Cross and rise again the 3rd day. Obviously the religious leaders did not accept what Jesus said. They tried to stone Him to death, then and there.
"Then took they up stones to cast at him: but Jesus hid himself, and went out of the temple, going through the midst of them, and so passed by."
