Revelation 20 (1000 year reign) is, in context, a reward for those martyred during the tribulation. They will reign with Christ for 1000 year. There is no mention of that reign being on earth. Christ reigns in heaven.
Why would Jesus come to earth the first time, but not come to earth ever again?
The earth was not created for only 6,000 years of sin and death. The earth was created for the glory of God. The second coming is for the glory of God.
That precept was established in the OT Covenant.
"Remember the sabbath day, to keep it holy. Six days shalt thou labour, and do all thy work: But the seventh day is the sabbath of the Lord thy God: in it thou shalt not do any work."
That command was taken from another precedent from Genesis 1:
"For in six days the Lord made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the Lord blessed the sabbath day, and hallowed it."
That is why John could clearly state a thousand year period without sin and death from decay. A thousand years without Satan. A thousand years of humans reigning on earth with and under Christ on His glorious throne in Jerusalem surrounded by the camp of the saints, those 144k, the firstfruits of the Second Coming, final harvest.
"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 word subdue also comes from Genesis 1:
"So God created man in his own image, in the image of God created he him; male and female created he them. 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."
The first Sabbath was a Day of the Lord. The earth was subdued by the sons of God during the Day of the Lord.
"These are the generations of the heavens and of the earth when they were created, in the day that the Lord God made the earth and the heavens,"
Generations plural of all living things on the Day of the Lord singular. That first day of the Lord had 6 24 hour days and a period of a thousand years.
"Whereby the world that then was, being overflowed with water, perished: But the heavens and the earth, which are now, by the same word are kept in store, reserved unto fire against the day of judgment and perdition of ungodly men. But, beloved, be not ignorant of this one thing, that one day is with the Lord as a thousand years, and a thousand years as one day."
Those sons of God good or bad did not keep living on the earth that was new after Noah's flood, but Noah and his family repopulated the earth to this very day. Peter points out the next baptism is not of water, but fire.
So the church, the sons of God from Noah until the Second Coming will not live on nor populate the earth post the Second Coming. But Jesus once on the earth will gather a final harvest to subdue the earth. The 144k are the firstfruits.
"And I looked, and, lo, a Lamb stood on the mount Sion, and with him an hundred forty and four thousand, having his Father's name written in their foreheads. And I heard a voice from heaven, as the voice of many waters, and as the voice of a great thunder: and I heard the voice of harpers harping with their harps: And they sung as it were a new song before the throne, and before the four beasts, and the elders: and no man could learn that song but the hundred and forty and four thousand, which were redeemed from the earth. These are they which were not defiled with women; for they are virgins. These are they which follow the Lamb whithersoever he goeth. These were redeemed from among men, being
the firstfruits unto God and to the Lamb. And in their mouth was found no guile: for they are without fault before the throne of God."
These are not firstfruits since the Flood of Noah, ie representing the church. These are sealed alive on the earth after the Second Coming, the 5th and 6th Seals. Jesus sits on a throne in Jerusalem according to Matthew 25:31. That is not the GWT. God sits on the GWT, has since Genesis 1. The Word, Jesus, always on His right hand.
The throne in Jerusalem will be the one given to Satan for 42 months of AoD. Satan will never sit on the GWT. The sheep of Matthew 25 and the wheat of Matthew 13 go through the tribulation and wait on the sea of glass during the 42 months of Satan's AoD. These all return on white horses to the earth, not the church. The church and all sons of God wait in Paradise during the reign of Christ on that throne in Jerusalem until all things are subdued. The church, sons of God, descend from heaven as the New Jerusalem in the NHNE.
The NHNE replace the heavens and earth that return to God per Paul and John says they are found no more.
Those who go through the tribulation in safety, like Noah, remain on the earth to subdue the earth. The sons of God, like Enoch are translated out of the earth before such time of trouble, and will never return to earth to subdue the earth. Both Enoch and Noah are types, but one must understand why there is a difference throughout history. Even in Genesis there are 2 genealogies. One showing death, the other showing constant life. But even eternal life does not happen on earth. Those blessed with eternal life if not destroyed and in sheol, are enjoying that eternal life in Paradise the Garden in heaven.
The longest wait was for those redeemed waiting in Abraham's bosom for thousands of years, and we have people in modern times of a few generations arguing over if Jesus returns before or after the time of Jacob's trouble. Yes, the argument is as silly as those arguing over how many angels can fit on the head of a pin. People are not really arguing over what God has already decided or will decide. They are arguing over their own personal understanding of God's plan. The only thing that changes God's plan is prayer and repentance, not telling others what you think is going to happen.
The Day of the Lord is not about death, even though death is the last enemy. The last time death is used is when that rebel protest is consumed by fire after the thousand years and Satan is loosed to deceive once more. Those who listen and follow Satan always end up dead. Satan is cast into the LOF. Death is cast into the LOF.
Amil claim the end is the end of 6 days. Premill point out the end is after 7 days. There is no Scriptural justification to say the 7th day is actually the 5th and 6th Days, combined.
