"After this I looked, and there before me was a great multitude that no one could count, from every nation, tribe, people and language, standing before the throne and before the Lamb. They were wearing white robes and were holding palm branches in their hands.
Then one of the elders asked me, 'These in white robes—who are they, and where did they come from?' I answered, 'Sir, you know.' And he said, 'These are they who have come out of the great tribulation; they have washed their robes and made them white in the blood of the Lamb." (Revelation 7:9,13-14 NIV)
A great multitude that no one could count, from every nation, tribe, people and language come out of the great tribulation washed and made white - an intended outcome of God's ultimate apocalypse.
Heb:12:22-28:
But ye are come unto mount Sion,
and unto the city of the living God,
the heavenly Jerusalem,
and to an innumerable company of angels,
To the general assembly and church of the firstborn,
which are written in heaven,
and to God the Judge of all,
and to the spirits of just men made perfect,
And to Jesus the mediator of the new covenant,
and to the blood of sprinkling,
that speaketh better things than that of Abel.
See that ye refuse not him that speaketh.
For if they escaped not who refused him that spake on earth,
much more shall not we escape,
if we turn away from him that speaketh from heaven:
Whose voice then shook the earth:
but now he hath promised,
saying,
Yet once more I shake not the earth only,
but also heaven.
And this word,
Yet once more,
signifieth the removing of those things that are shaken,
as of things that are made,
that those things which cannot be shaken may remain.
Wherefore we receiving a kingdom which cannot be moved,
let us have grace,
whereby we may serve God acceptably with reverence and godly fear:
Heb:12:6:
For whom the Lord loveth he chasteneth,
and scourgeth every son whom he receiveth.
Heb:12:7:
If ye endure chastening,
God dealeth with you as with sons;
for what son is he whom the father chasteneth not?
Heb:12:8:
But if ye be without chastisement,
whereof all are partakers,
then are ye bastards,
and not sons.
Isa:65:17:
For,
behold,
I create new heavens and a new earth:
and the former shall not be remembered,
nor come into mind.
Isa:65:18:
But be ye glad and rejoice for ever in that which I create:
for,
behold,
I create Jerusalem a rejoicing,
and her people a joy.
Isa:65:19:
And
I will rejoice in Jerusalem,
and joy in my people:
and the voice of weeping shall be no more heard in her,
nor the voice of crying.
Re:21:1-4:
And I saw a new heaven and a new earth:
for the first heaven and the first earth were passed away;
and there was no more sea.
And I John saw the holy city,
new Jerusalem,
coming down from God out of heaven,
prepared as a bride adorned for her husband.
And I heard a great voice out of heaven saying,
Behold,
the tabernacle of God is with men,
and he will dwell with them,
and they shall be his people,
and God himself shall be with them,
and be their God.
And God shall wipe away all tears from their eyes;
and there shall be no more death,
neither sorrow,
nor crying,
neither shall there be any more pain:
for the former things are passed away.
Isa:65:24:
And it shall come to pass,
that before they call,
I will answer;
and while they are yet speaking,
I will hear.
Isa:65:25:
The wolf and the lamb shall feed together,
and the lion shall eat straw like the bullock:
and dust shall be the serpent's meat.
They shall not hurt nor destroy in all my holy mountain,
saith the LORD.
