I'm sorry to ask technical questions, but it's really confusing to me.
So, if we are present on earth during this millennia, we all still die because we are still bound by the natural laws of the earth.
But, if this occurs after the wrath, the wrath itself will do such incredible damage that the world would not be inhabitable. So I still may have the sequence of events out of order.
Good day, OR,
If by "this millennia" you are referring to the millennial kingdom, the church will have already been changed into their immortal and glorified bodies and will rule with Christ, as will the 144,000 out of Israel and the resurrected great tribulation saints. Those of the great tribulation saints who make it alive through the entire tribulation period, along with the remnant of Israel, will enter into the millennial kingdom in their mortal bodies and will repopulate the earth. Regarding the sequence of events, here is a bit of a directory:
*
You are here
* Christ descends from heaven to the air and gathers the church (John 14:1-3, 1 Thess.4:16-17, 1 Cor.15:51-53, Rev.4:1)
* God's wrath (Day of the Lord) begins via the seals, trumpets and bowl judgment (Rev. Chapters 6 thru 18)
* Majority of the earth's population decimated and all human government dismantled
* Jesus returns to the earth to end the age after God's wrath is completed, i.e. after the 7th bowl (Rev.16:17, 19:11-21)
* Beast and false prophet are cast into the lake of fire alive (Rev.19:20)
* All of the surviving wicked are killed by the Lord's double-edged sword (Rev.19:15, 21)
* Satan is restricted in the Abyss (Rev.20:1-3)
* Great Tribulation Saints resurrected (Rev.20:4-6)
* Thousand year reign of Christ (a thousand years mentioned six times in Rev.20:1-7)
* Satan released at the end of the thousand years for one last deception (Rev.20:7)
* Satan cast into the lake of fire - (Rev.20:10)
* Great White Throne judgment (Judgment for all of the unrighteous dead throughout all of history) - (Rev.20:11-15)
* New Heaven, New Earth, New Jerusalem - (Revelation chapters 21 & 22)
Now regarding your concern, you are correct in that after all of the seals, trumpets and bowl judgments, as well as the plagues that the two witnesses will cause, that the earth will be a chaotic mess! For the seas and all of the fresh water will have been turned into literal blood at the 2nd and 3rd bowl judgments, the majority of the population will have been decimated, the cities of the nations will have collapsed and much more.
All that said, though not mentioned, I believe when the Lord returns to the earth to end the age, that He will for a lack of a better word, renovate the earth for the millennial kingdom to make it habitable. I am reminded of the prophecy regarding the millennial temple described in detail in Ezekiel chapters 40-48 and the mentioning of the waters teaming with fish, etc.
There are some who believe and teach that prior to the thousand years, that this is when the prophecy in 2 Peter 3:10 takes place where heaven and earth and everything in it will melt with fervent heat, being destroyed by fire and laid bare. However, if that was the case, I would be asking the question as to what God does with all of the people who will have survived the tribulation period. He would have to remove them from the earth prior to burning it up and then put them back in it. And because everything will have been burned up, then there would be no swords to beat into blow shares and no spears to be fashioned into pruning hooks (Isaiah 2:4), nor would there be any fresh water or oceans.
However, scripture points to this event of the heaven and the earth being destroyed as taking place after the millennial kingdom, which would also make more sense, as there will be no one left on the earth at that time when God burns it up. Regarding this, the Father says the following regarding His Son in regards to the end of this present heavens and earth:
=========================================
“In the beginning, O Lord, You laid the foundations of the earth,
and the heavens are the work of Your hands.
They will perish, but You remain;
they will all wear out like a garment.
You will roll them up like a robe;
like a garment they will be changed;
but You remain the same,
and Your years will never end.”
=====================================================
I hope that this was beneficial
