What I can feel is the sarcasm oozing from your opening sentence.

The ones in the 7 Churches that are said to be in need of overcoming certain things, are they part of the gathered Church or do they end up on the rubble pile?

Re:22:11:
He that is unjust,
let him be unjust still:
and he which is filthy,
let him be filthy still:
and he that is righteous,
let him be righteous still:
and he that is holy,
let him be holy still.

Being called Satan by a false Christian, what is the world coming to? Do you keep a collection of your 'scars for Christ'?

Zec:13:6:
And one shall say unto him,
What are these wounds in thine hands?
Then he shall answer,
Those with which I was wounded in the house of my friends.

How do you handle it when you should be cringing? The verse below has an almost casual mention of the Nations that in reality sees 2/3 of them being dead on the spot and the ones lifted off the ground are dropped onto a rubble pile from a great height. The mush that is left es eaten by birds and animals brought there by God for that specific purpose. Several billion dead in a few hours, the sea as a dead man means it is a solid piece that you can/do walk on for the next 1,000 years. The difference being 1/3 of life in the ocean dies before Satan is even around for his allotted time, then it takes him 1110 days to kill just over 2 Billion people, that is the Bible's definition of the last tribulation caused by sinners. Cleaning out the sinners is messy work, that is partly why it is done so quickly, 3 hours out of one afternoon from start to finish.
It still gets the added 'great' because it is the greater of the two.

If that bridge follows the doctrine path it is a whopper also, not that it is all fabrication only that you need to read several websites and then you will have no questions, yet not one point can be backed up in that it includes a lot of other prophecy also.

I forgot to post this verse about gentiles being killed but in the off handed way in that it is far from being very important when a lot of other verses say it is going to be pretty bad.

Eze:39:6:
And I will send a fire on Magog,
and among them that dwell carelessly in the isles:
and they shall know that I am the LORD.

Zec:13:8:
And it shall come to pass,
that in all the land,
saith the LORD,
two parts therein shall be cut off and die;
but the third shall be left therein.

Jer:25:32:
Thus saith the LORD of hosts,
Behold,
evil shall go forth from nation to nation,
and a great whirlwind shall be raised up from the coasts of the earth.
Jer:25:33:
And the slain of the LORD shall be at that day from one end of the earth even unto the other end of the earth:
they shall not be lamented,
neither gathered,
nor buried;
they shall be dung upon the ground.


Re:19:21:
And the remnant were slain with the sword of him that sat upon the horse,
which sword proceeded out of his mouth:
and all the fowls were filled with their flesh.

Da:2:34:
Thou sawest till that a stone was cut out without hands, which smote the image upon his feet that were of iron and clay,
and brake them to pieces.
Da:2:35:
Then was the iron,
the clay,
the brass,
the silver,
and the gold,
broken to pieces together,
and became like the chaff of the summer threshingfloors; and the wind carried them away,
that no place was found for them:
and the stone that smote the image became a great mountain,
and filled the whole earth.

The prophecy is pretty specific, does it fit with the previous verses in the area defined is the same in all and the area defined in association with kingdoms and the 7th trump in Re:11. Ther is a lot of OT prophecy that belong to that specific event, Daniel is as good a place to start as any.

Da:2:36:
This is the dream;
and we will tell the interpretation thereof before the king.

Da:2:44:
And in the days of these kings shall the God of heaven set up a kingdom,
which shall never be destroyed:
and the kingdom shall not be left to other people,
but it shall break in pieces and consume all these kingdoms,
and it shall stand for ever.
Da:2:45:
Forasmuch as thou sawest that the stone was cut out of the mountain without hands,
and that it brake in pieces the iron,
the brass,
the clay,
the silver,
and the gold;
the great God hath made known to the king what shall come to pass hereafter:
and the dream is certain,
and the interpretation thereof sure.

Re:18:17-24:
For in one hour so great riches is come to nought.
And every shipmaster,
and all the company in ships,
and sailors,
and as many as trade by sea,
stood afar off,
And cried when they saw the smoke of her burning,
saying,
What city is like unto this great city!
And they cast dust on their heads,
and cried,
weeping and wailing,
saying,
Alas,
alas,
that great city,
wherein were made rich all that had ships in the sea by reason of her costliness!
for in one hour is she made desolate.
Rejoice over her,
thou heaven,
and ye holy apostles and prophets;
for God hath avenged you on her.
And a mighty angel took up a stone like a great millstone,
and cast it into the sea,
saying,
Thus with violence shall that great city Babylon be thrown down,
and shall be found no more at all.
And the voice of harpers,
and musicians,
and of pipers,
and trumpeters,
shall be heard no more at all in thee;
and no craftsman,
of whatsoever craft he be,
shall be found any more in thee;
and the sound of a millstone shall be heard no more at all in thee;
And the light of a candle shall shine no more at all in thee;
and the voice of the bridegroom and of the bride shall be heard no more at all in thee:
for thy merchants were the great men of the earth;
for by thy sorceries were all nations deceived.
And in her was found the blood of prophets,
and of saints,
and of all that were slain upon the earth.

That He gives His justification is going to be small comfort to the ones on the dead end of the grave on that day, however (and this point is largely left out, they have altered their perspective by the time they stand before God, that is the way God does things, when you know what checkmate looks like it is pretty easy to play the game in reverse and win every single time.

What will make 'good reading' is the witness reports from the 1/3 that live through and survive the time the trumps take, (the first one is the trip from where you are on the planet when the 'rapture has just taken 2/3 of all the people around you and you and any around you 'get the urge to walk to Jerusalem' and that task is completed in a few months. That is the first of 1,000 such trips so I assume when the yearly feast comes to an end you are free to travel in any direction and everyplace you go a bit of rain follows you or something like that.
When Satan is released with the other fallen angels the ones alive for the 1,000 years are in Israel for that yearly feast and like the beginning they continue to be witnesses to what the Kingdom of God is like (so far).

Being a pre-tribber means you see only the very last part so you don't escape the fire anyway. Trib for a believer is just as hard as being a believer on any given day, unless you see something in this reference that escapes me.

1Pe:4:12-18:
Beloved,
think it not strange concerning the fiery trial which is to try you,
as though some strange thing happened unto you:
But rejoice,
inasmuch as ye are partakers of Christ's sufferings;
that,
when his glory shall be revealed,
ye may be glad also with exceeding joy.
If ye be reproached for the name of Christ,
happy are ye;
for the spirit of glory and of God resteth upon you:
on their part he is evil spoken of,
but on your part he is glorified.
But let none of you suffer as a murderer,
or as a thief,
or as an evildoer,
or as a busybody in other men's matters.
Yet if any man suffer as a Christian,
let him not be ashamed;
but let him glorify God on this behalf.
For the time is come that judgment must begin at the house of God:
and if it first begin at us,
what shall the end be of them that obey not the gospel of God?
And if the righteous scarcely be saved,
where shall the ungodly and the sinner appear?

Just another day would also be false advertising, there are a lot of 'sinners' that Satan could use as filling his quota and 'believers would be tricked into thinking it is the real deal. If you are going to kill all the believers to make believers out of non-believers then you just do it, you don't need any deception.
