> In Luke 19.11-27, Jesus tells a parable about "when the kingdom of God appears."
I disagree with that sentence. Here's Luke 19 in the ESV. Verse 11 says that Jesus "proceeded to tell a parable, because he was near to Jerusalem, and because they supposed that the kingdom of God was to appear immediately."
> Since the book of Revelation describes heaven as being on this earth (Rev. 21.2), and it describes heaven as a city (Rev. 21.10)
Here's Revelation 21:1-12 in the ESV:
Then I saw a new heaven and a new earth, for the first heaven and the first earth had passed away, and the sea was no more. 2 And I saw the holy city, new Jerusalem, coming down out of heaven from God, prepared as a bride adorned for her husband. 3 And I heard a loud voice from the throne saying, “Behold, the dwelling place[a] of God is with man. He will dwell with them, and they will be his people,[b] and God himself will be with them as their God.[c] 4 He will wipe away every tear from their eyes, and death shall be no more, neither shall there be mourning, nor crying, nor pain anymore, for the former things have passed away.”
5 And he who was seated on the throne said, “Behold, I am making all things new.” Also he said, “Write this down, for these words are trustworthy and true.” 6 And he said to me, “It is done! I am the Alpha and the Omega, the beginning and the end. To the thirsty I will give from the spring of the water of life without payment. 7 The one who conquers will have this heritage, and I will be his God and he will be my son. 8 But as for the cowardly, the faithless, the detestable, as for murderers, the sexually immoral, sorcerers, idolaters, and all liars, their portion will be in the lake that burns with fire and sulfur, which is the second death.”
The New Jerusalem
9 Then came one of the seven angels who had the seven bowls full of the seven last plagues and spoke to me, saying, “Come, I will show you the Bride, the wife of the Lamb.” 10 And he carried me away in the Spirit to a great, high mountain, and showed me the holy city Jerusalem coming down out of heaven from God, 11 having the glory of God, its radiance like a most rare jewel, like a jasper, clear as crystal. 12 It had a great, high wall, with twelve gates, and at the gates twelve angels, and on the gates the names of the twelve tribes of the sons of Israel were inscribed—
Verse 2 does not describe "heaven as being on this earth". It states "And I saw the holy city, new Jerusalem, coming down out of heaven from God, prepared as a bride adorned for her husband".
Verse 10 does not describe "heaven as a city". It states "And he carried me away in the Spirit to a great, high mountain, and showed me the holy city Jerusalem coming down out of heaven from God".
