I can list entire chapters if you want but it approaches the character limit. I'm always careful to pull full portions of passages that do not change the context but here are full passages to show that this is a physical event.
Revelation: 21:1-27 [my brackets are to call your attention to the bold]
Then I saw a new heaven and a new earth for the first heaven and earth had passed away, and the sea was no more.
[Question: do we still have seas right now?]
2 I saw the holy city, the new Jerusalem, coming down out of heaven from God, prepared as a bride adorned for her husband.
[Question: Is Heaven a different location than Earth right now?]
3 And I heard a loud voice from the throne saying: “Behold, the dwelling place of God is with man, and He will dwell with them. They will be His people, and God Himself will be with them as their God.
[Can't be any clearer here.]
4‘He will wipe away every tear from their eyes,’ and there will be no more death or mourning or crying or pain, for the former things have passed away.”
[Question: Does mankind still currently die these days? And what were the original enemies of mankind in the garden?]
5 And the One seated on the throne said, “Behold, I make all things new.” Then He said, “Write this down, for these words are faithful and true.”
[It's going to happen as written.]
6 And He told me, “It is done! I am the Alpha and the Omega, the Beginning and the End. To the thirsty I will give freely from the spring of the water of life. 7 The one who overcomes will inherit all things, and I will be his God, and he will be My son.
8 But to the cowardly and unbelieving and abominable and murderers and sexually immoral and sorcerers and idolaters and all liars, their place will be in the lake that burns with fire and sulfur. This is the second death.”
[Question: Have all the bad people been placed in the spiritual fiery lake?]
9 Then one of the seven angels with the seven bowls full of the seven final plagues came and said to me, “Come, I will show you the bride, the wife of the Lamb.”
10 And he carried me away in the Spirit to a mountain great and high, and showed me the holy city of Jerusalem coming down out of heaven from God, 11 shining with the glory of God. Its radiance was like a most precious jewel, like a jasper, as clear as crystal.
[Question: is heaven a different location than Earth right now?]
12 The city had a great and high wall with twelve gates inscribed with the names of the twelve tribes of Israel, and twelve angels at the gates. 13 There were three gates on the east, three on the north, three on the south, and three on the west. 14 The wall of the city had twelve foundations bearing the names of the twelve apostles of the Lamb.
15 The angel who spoke with me had a golden measuring rod to measure the city and its gates and walls. 16 The city lies foursquare, with its width the same as its length. And he measured the city with the rod, and all its dimensions were equal—12,000 stadiad in length and width and height. 17 And he measured its wall to be 144 cubits,e by the human measure the angel was using.
18 The wall was made of jasper, and the city itself of pure gold, as pure as glass. 19 The foundations of the city walls were adorned with every kind of precious stone:
The first foundation was jasper, the second sapphire, the third chalcedony, the fourth emerald, the fifth sardonyx, the sixth carnelian, the seventh chrysolite, the eighth beryl, the ninth topaz, the tenth chrysoprase, the eleventh jacinth, and the twelfth amethyst.
21 And the twelve gates were twelve pearls, with each gate consisting of a single pearl. The main street of the city was pure gold, as clear as glass.
[Question: (Ephesians 2:19-22), can you explain what each element means in light of the church?]
22 But I saw no temple in the city, because the Lord God Almighty and the Lamb are its temple. 23 And the city has no need of sun or moon to shine on it, because the glory of God illuminates the city, and the Lamb is its lamp. 24 By its light the nations will walk, and into it the kings of the earth will bring their glory. 25 Its gates will never be shut at the end of the day, because there will be no night there.
[The city will glow. This is a physical light. Moses was physically glowing after he was in the presence of The Almighty for many days (Exodus 34:29-35). During the transfiguration, the Messiah, Moses, and Elijah were seen glowing (Matthew 17:1–8, Mark 9:2–13, Luke 9:28–36). Paul explains that different bodies will have different shines (1 Cor 15:35-41)]
26 And into the city will be brought the glory and honor of the nations.
[The nations will still exist and send tribute to the city.]
27 But nothing unclean will ever enter it, nor anyone who practices an abomination or a lie, but only those whose names are written in the Lamb’s Book of Life.
[There will still be corrupt people living in the nations (Zechariah 14). This is a physical city that is separate from them.]
Revelation 22:1-21
Then the angel showed me a river of the water of life, as clear as crystal, flowing from the throne of God and of the Lamb down the middle of the main street of the city. On either side of the river stood a tree of life, bearing twelve kinds of fruit and yielding a fresh crop for each month. And the leaves of the tree are for the healing of the nations.
[Question: Why would there need to be leaves that can heal the nations? And what does the fruit represent if not physical fruit?]
3 No longer will there be any curse. The throne of God and of the Lamb will be within the city, and His servants will worship Him. 4 They will see His face, and His name will be on their foreheads.
[Question: Do you currently see the Father's face? If so what does He look like?]
5 There will be no more night in the city, and they will have no need for the light of a lamp or of the sun. For the Lord God will shine on them, and they will reign forever and ever.
[The city will glow. This is a physical light.]
Then the angel said to me, “These words are faithful and true. The Lord, the God of the spirits of the prophets, has sent His angel to show His servants what must soon take place.”
[It's going to happen as written.]
7“Behold, I am coming soon. Blessed is the one who keeps the words of prophecy in this book.”
[We must keep the words of this book.]
8 And I am John, who heard and saw these things. And when I had heard and seen them, I fell down to worship at the feet of the angel who had shown me these things. 9 But he said to me, “Do not do that! I am a fellow servant with you and your brothers the prophets, and with those who keep the words of this book. Worship God!”
[Again, an emphasis on keeping the words of this book.]
10 Then he told me, “Do not seal up the words of prophecy in this book, because the time is near. 11 Let the unrighteous continue to be unrighteous, and the vile continue to be vile; let the righteous continue to practice righteousness, and the holy continue to be holy.”
[And now a command not to close up the words of this book.]
12“Behold, I am coming soon, and My reward is with Me, to give to each one according to what he has done. 13 I am the Alpha and the Omega, the First and the Last, the Beginning and the End.”
[Question: Why does he say he's coming soon if he's already "here" in us?]
14 Blessed are those who wash their robes, so that they may have the right to the tree of life and may enter the city by its gates. 15 But outside are the dogs, the sorcerers, the sexually immoral, the murderers, the idolaters, and everyone who loves and practices falsehood.
[There will still be corrupt people living in the nations (Zechariah 14). This is a physical city that is separate from them.]
16“I, Jesus, have sent My angel to give you this testimony for the churches. I am the Root and the Offspring of David, the bright Morning Star.” 17 The 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.
18 I testify to everyone who hears the words of prophecy in this book: If anyone adds to them, God will add to him the plagues described in this book. 19 And if anyone takes away from the words of this book of prophecy, God will take away
Amen.
