That's a book (Revelation) written by someone other than Jesus, and totally unreliable as a source for anything Jesus might have said or done.
Jesus didn't teach anything in Revelation.
I have think whoever wrote Revelation, was either delusional or tripping on something like LSD...or both.
Revelation 1:1; Revelation 1:4 is telling us that gospel writer John wrote the book of Revelation.
Jesus was long resurrected to heaven before John wrote Revelation.
Revelation was written for our day or time frame, and Not the first century - Revelation 1:10
There are corresponding cross-reference verses and passages in Revelation connecting to other Bible books ( especially Daniel )
So, although written in very-vivid word pictures it is Not some delusion.
Jesus is the faithful and true witness to Revelation according to Revelation 1:5; Revelation 19:11-13
Didn't Jesus teach the humble meek people would inherit the Earth at Matthew 5:5 ?_______
In order for the meek to inherit the Earth, then Earth would Not only have to be here, but there would be good conditions exiting on Earth.
Revelation 22:2 shows us the return of the Genesis ' tree of life ' for the healing of Earth's nations under Christ's rulership over Earth.
That is why there is the invitation for us at Revelation 22:20 for Jesus to come ! Come and usher in global Peace on Earth among people of goodwill.
