Revelation 7

At what appears the closing of the sixth seal, John sees -

"...four angels standing on the four corners of the earth, holding the four winds of the earth, that the wind should not blow on the earth, nor on the sea, nor on any tree.
2 And I saw another angel ascending from the east, having the seal of the living God: and he cried with a loud voice to the four angels, to whom it was given to hurt the earth and the sea,
3 Saying, Hurt not the earth, neither the sea, nor the trees, till we have sealed the servants of our God in their foreheads."  (New Testament | Revelation 7:1 - 3)

In modern day, we learn of these -

"...four angels sent forth from God, to whom is given power over the four parts of the earth, to save life and to destroy; these are they who have the everlasting gospel to commit to every nation, kindred, tongue, and people; having power to shut up the heavens, to seal up unto life, or to cast down to the regions of darkness."  (Doctrine and Covenants | Section 77:8)

And -

"...that the angel ascending from the east is he to whom is given the seal of the living God over the twelve tribes of Israel; wherefore, he crieth unto the four angels having the everlasting gospel, saying: Hurt not the earth, neither the sea, nor the trees, till we have sealed the servants of our God in their foreheads. And, if you will receive it, this is Elias which was to come to gather together the tribes of Israel and restore all things." (Doctrine and Covenants | Section 77:9)

First, winds have always been considered a living and destructive force in the scriptures.  Obviously, this was a period of great missionary work, where the gospel of Jesus Christ would  be preached througout the world.  We also learn that -

"...the number of them which were sealed: and there were sealed an hundred and forty and four thousand of all the tribes of the children of Israel."  (New Testament | Revelation 7:4)

And in addition to these -

"...a great multitude, which no man could number, of all nations, and kindreds, and people, and tongues, stood before the throne, and before the Lamb, clothed with white robes, and palms in their hands..."  (New Testament | Revelation 7:9)

Of all of these we learn -

"...These are they which came out of great tribulation, and have washed their robes, and made them white in the blood of the Lamb.
15 Therefore are they before the throne of God, and serve him day and night in his temple: and he that sitteth on the throne shall dwell among them.
16 They shall hunger no more, neither thirst any more; neither shall the sun light on them, nor any heat.
17 For the Lamb which is in the midst of the throne shall feed them, and shall lead them unto living fountains of waters: and God shall wipe away all tears from their eyes."  (New Testament | Revelation 7:14 - 17)

I want to note that it seems everyone will experience "great tribulation".  But if they overcome or "come out of" suggesting faith, repentance, ordinances, and covenants, what greater promises are there.
