The 'heaven' it speaks of here is actually the atmosphere(1st heaven). The reason it needs to be replaced is because it's cursed with the earth. Thus both of them are made brand new.
The 2nd & 3rd heaven is uncorrupted, so they don't need to be replaced.
This is correct.
Another reason for the new heaven & earth is because the New Jerusalem is somewhere between 1200 - 1500 miles square, so there's no room for it on our present earth or atmosphere..
yeah bro I was talking about this part
“So then after the Lord had spoken unto them,
he was received up into heaven, and sat on the right hand of God.”
Mark 16:19 KJV
this heaven
“The Lord is
in his holy temple, the Lord's throne is in heaven: his eyes behold, his eyelids try, the children of men.”
Psalm 11:4 KJV
this place where the church is with the lord
“After this I beheld, and, lo, a great multitude, which no man could number,
of all nations, and kindreds, and people, and tongues, stood before the throne, and before the Lamb, clothed with white robes, and palms in their hands;
And cried with a loud voice, saying,
Salvation to our God which sitteth upon the throne, and unto the Lamb. And all the angels stood round about the throne, and about the elders and the four beasts, and fell before the throne on their faces, and worshipped God,
And one of the elders answered, saying unto me, What are these which are arrayed in white robes? and whence came they? And I said unto him,
Sir, thou knowest. And he said to me, These are they which came out of great tribulation, and have washed their robes, and made them white in the blood of the Lamb.
Therefore are they before the throne of God, and serve him day and night in his temple: and he that sitteth on the throne shall dwell among them. They shall hunger no more, neither thirst any more; neither shall the sun light on them, nor any heat. For the Lamb which is in the midst of the throne shall feed them, and shall lead them unto living fountains of waters: and God shall wipe away all tears from their eyes.”
Revelation 7:9-11, 13-17 KJV
That place that’s made new already Where they sing of salvstion and weep for the earth as you see here heaven is already new and the kingdom is in swing in heaven but the earth is going through a trial
“And I heard a loud voice saying
in heaven, Now is come salvation, and strength, and the kingdom of our God, and the power of his Christ: for the accuser of our brethren is cast down, which accused them before our God day and night. And they overcame him by the blood of the Lamb, and by the word of their testimony; and they loved not their lives unto the death.
Therefore
rejoice, ye heavens, and ye that dwell in them.
Woe to the inhabiters of the earth and of the sea! for the devil is come down unto you, having great wrath, because he knoweth that he hath but a short time.”
Revelation 12:10-12 KJV
When his time runs out the kingdom in heaven will return to earth and usher in eternity
