Dispair you said: Our earth and heaven(space or the air) and the sea will remain forever or however long it can survive natural phenomena and entropy.
The earth(our foundation of understanding), heaven(spiritual truth) and the sea(those lost in confusion) will definitely change or be renewed or totally disappear.
Do you feel that when John was under the power of Holy spirit and read or contemplated the words of Genesis, and used the same symbols in his writings in Revelation he had the literal in mind? - Hear what the spirit says!
The old physical earth, heaven and sea will still exist after the new Jerusalem arrives: Revelation 22:
14Blessed are those who wash their robes,
a so that they may have the right to the tree of life and may enter the city by its gates.
15But outside are the dogs, the sorcerers, the sexually immoral, the murderers, the idolaters, and everyone who loves and practices falsehood.
The kingdom is no part of this world. Hoping for the physical earth and heaven to be renewed is the thinking of man, not God. Does the flesh still have such a hold on us after all this time and effort? I fear the point of the Lords sacrifice is lost on us.
17The Spirit and the bride say, “Come!” Let the one who hears say, “Come!” And let the one who is thirsty come, and the one who desires the water of life drink freely.

What is your take on these scriptures that seem to dispute what you are saying. There is nothing on this earth that will remain as all things will become new again.
2 Peter 3:10 But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up.
Rev 21:1 And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea.
Rev 21:5 And he that sat upon the throne said, Behold, I make all things new. And he said unto me, Write: for these words are true and faithful.
The kingdom of God is something we can not physically see as the kingdom of God dwells in those who are Spiritually born again that are in Christ and He in them, John 3:5-7; 12:44-50; John 15:5.
Luke 17:20 And when he was demanded of the Pharisees, when the kingdom of God should come, he answered them and said, The kingdom of God cometh not with observation: 21 Neither shall they say, Lo here! or, lo there! for, behold, the kingdom of God is within you.[/QUOTE]
Lets take the sea mentioned in Rev21:1 for example to explain how I see all these: For me the sea symbolizes mankind in a state where its overwhelmed with information (true and false); being pushed hence and forth by the waves.
This is why our Lord made his apostles fishers of men - to save them from the state of misinformation in the sea.
This is why the Hebrews passes on dry land through the red sea guided by God, but the Egyptians were overcome by the waves and waters.
This is the reason for the walking on water miracle - to show that our Lord brings information that calms the sea of confusion.
This is the symbolic meaning of our immersion in baptism - showing we overcome the sea of confusion and rise up in truth.
This is the reason why the world was covered in flood waters in Noah's day - to show that those that persue the spirit or are drawn by it can survive the waters but the others are drowned.
This is why the Beast of revelation rises up out of the sea - the sea of information we find ourselves in inclines us to embrace our own will of flesh, forming worldly governments and giving rise to the beast.
This is why the Dragon spews a flood of water (misinformation or sea) after pure worship (the woman) in revelation 12:15.
This is why the Earth (our foundation of understanding) was cover in water during the creation story. But God caused the dry earth to appear.
So for me when I read that there will be no more sea, I realize that there would no longer be a situation where we are confused by overwhelming information and washed hence and forth. There will be a new Heaven, a purified spiritual truth that was rid of the devil by the blood of our Lord. There will be a new earth, a restored foundation of understanding for mankind. This is the creation story of Genesis, and this is the restoration story of Revelation and the meaning of the Crucifixion for me.
Parables and symbolism make the Bible a sword that kills the flesh and its material desires - and leaves the spirit to re-enter the paradise of Eden. Genesis 3:
23Therefore the LORD God banished him from the Garden of Eden to work the ground from which he had been taken. 24So He drove out the man and stationed cherubim to the east of the Garden of Eden, with a whirling sword of flame to guard the way to the tree of life.
