Your talk of "old creation" and "new creation" betrays the fact that you do not understand what "I make all things new" means. The same creation, made new again. Jesus did not say, "Behold, I create all things new".
There is nothing in the Revelation of the new heavens and new earth that suggests that either the abyss or the lake of fire will have ceased to exist. In fact, the description of the new heavens and new earth repeatedly mentions the lake of fire, comparing New Jerusalem with the lake of fire. Where did Satan exist in the Garden of Eden?
Your talk of the Day of the LORD as though it's a thousand-year long sabbath betrays the fact that you conflate the Day of judgment when Christ returns, a.k.a the Day of Christ, with the entire millennium. The beast and false prophet are not going to slowly descend into the lake of fire over a period of a thousand years.
Actually John did say that the old would flee away. Jesus said heaven and earth would pass away. Paul said all would be made subject to God, and God alone would exist.
Revelation 21 is an entirely new and different creation. That is why we distinguish it as the NHNE. Isaiah 65 is not the NHNE. Isaiah 65 is current creation made new.
"For, behold, I create new heavens and a new earth: and the former shall not be remembered, nor come into mind. But be ye glad and rejoice for ever in that which I create: for, behold, I create Jerusalem a rejoicing, and her people a joy. And I will rejoice in Jerusalem, and joy in my people: and the voice of weeping shall be no more heard in her, nor the voice of crying."
Even in Zechariah 14 we see that action take place in part with Jerusalem.
"And it shall come to pass in that day, that the light shall not be clear, nor dark: But it shall be one day which shall be known to the Lord, not day, nor night: but it shall come to pass, that at evening time it shall be light. And it shall be in that day, that living waters shall go out from Jerusalem; half of them toward the former sea, and half of them toward the hinder sea: in summer and in winter shall it be. And the Lord shall be king over all the earth: in that day shall there be one Lord, and his name one. All the land shall be turned as a plain from Geba to Rimmon south of Jerusalem: and it shall be lifted up, and inhabited in her place, from Benjamin's gate unto the place of the first gate, unto the corner gate, and from the tower of Hananeel unto the king's winepresses. And men shall dwell in it, and there shall be no more utter destruction; but Jerusalem shall be safely inhabited."
This does not happen in Revelation 19, 20, nor 21. Isaiah 65 and Zechariah 14 start at the 6th Seal even before the 1st Trumpet in Revelation starts to sound. The destruction of the day of judgment is part of this creation process.
"And I beheld when he had opened the sixth seal, and, lo, there was a great earthquake; and the sun became black as sackcloth of hair, and the moon became as blood; And the stars of heaven fell unto the earth, even as a fig tree casteth her untimely figs, when she is shaken of a mighty wind. And the heaven departed as a scroll when it is rolled together; and every mountain and island were moved out of their places."
God moves the entire earth around and no one will remember what the earth looks like today at that point. That is when Isaiah 65's creation happens. Not in Revelation 21. Amil also like to skip past all the pertinent detail and make Isaiah 65 the NHNE.
Revelation 21 does not even have to mention a creation, but we understand that John is not seeing this creation, nor the creation of the 6th Seal. John is seeing a totally different heaven and earth. Then John tries to describe that creation with stuff and terms from our current creation we still remember, but that does not mean he is talking about our current creation, simply changed around.
You keep conflating the Second Coming with the Day of the Lord and betray the fact you do not know the difference between them.
Then you deflect and question that it takes Jesus a thousand years to "get things done". Well if that is your interpretation of the Millennium why does it take Jesus a thousand years to get the NHNE correct? You have the New Jerusalem coming down a thousand years later. Does Satan's rebel army destroy the old Jerusalem after the first thousand years?
I pointed out the LOF is a separate creation from both this current creation and the NHNE. Evidently people cannot see 2 "universes" side by side. Not two worlds. Not two galaxies. Not even two solar systems. The Lord God exists outside of this creation. The LOF will also exist outside of this creation. The LOF is not part of this creation nor the next but an entire separate creation by itself.
That old serpent is referring to Satan in the Garden of Eden. Is there another old serpent other than the one who deceived Eve?
"And he laid hold on the dragon, that old serpent, which is the Devil, and Satan, and bound him a thousand years,"
Satan is the only being who goes around deceiving God's creation that leads to rebellion against God.
