YOU believe that a literal, physical new heaven
and earth are set up.

YOU believe that this happens AFTER sinners
are judged.

YOU believe that the new earth is occupied
by believers, who now have physical, eternal
bodies.

YOU believe that a literal, physical, "New Jerusalem"
comes down onto this "new earth" AFTER this all
happens.

So I asked you, who are the sinners spoken of,
in Revelation 22:14-15, who are outside the
gates of the New Jerusalem, if all of the sinners
have been judged already and this "new earth"
has only believers on it?

They cannot be, as you said, "those who are ejected
by Christ into Hades, which shall at that time be
thrown into Hell", since that already have taken
place.

So if what you believe is true, then who are they
and where did they come from?

It says they are "without". This does not necessitate
they are leaning up against the outside of the gate doors,
and still in the new earth. Without simply shows they
are not in the city with those who believe, but are
"without" it, e.g. in the "lake of fire". The lake of fire
IS "without" (outside of, not in) the city.

That doesn't work. You are now trying to claim
that the lake of fire that existed BEFORE this
"new earth" is somewhere on this "new earth".

According TO YOUR OWN DOCTRINE, all sinners
are already gone and this new earth is made and
then the New Jerusalem comes down.

So no, there shouldn't be any sinners on earth,
anywhere. And before you respond with
something like, "God can do whatever He wants",
all that response would mean, is that you know
you can't show me what you said Biblically and
that you still refuse to give up your doctrine.
So don't bother going there.

And yes, this passage places them outside
THE GATES of the city, not just "somewhere
on earth, burning in a lake of fire". Nor does
it mention the lake of fire there, regarding
these people.

The fact is, if they were in the lake of fire, they'd
be gone, period and wouldn't be mentioned as
being specifically outside of the gates of the city.

The Greek word means "outside". It is saying that
they are outside of the gates of the city. That plants
them squarely on Earth, outside the gates of the
city. If it were "somewhere on earth, in the lake
of fire", then that's what it would say.

And you didn't bother to take into account v14.

Revelation 22:14-15

14) Blessed are they that do his commandments,
that THEY may have right to the tree of life, and
may ENTER IN through the gates into the city.
15) For without (outside) are dogs, and sorcerers,
and whoremongers, and murderers, and idolaters,
and whosoever loveth and maketh a lie.

Now it clearly shows the contrast between those
who can enter into the gates and those who must
remain outside of the gates and cannot enter into
the city.

So once again I ask, Where did these people come from,
since all sinners are supposedly gone already?

Who says they have to be on the new earth?

It simply says they are "without".

Amazing, when Revelation 19 says Christ
comes from "heaven", and that the armies
of heaven follow Him to the battle with the
"kings of the earth", you insist He is not on
earth.
