Revelation 15.4-16.1

After this I looked, and the Temple of the Tent of Witness in Heaven was opened, and out of the Temple came the seven angels with the seven plagues, robed in pure bright linen, and their breasts girded with golden girdles.

And one of the four living creatures gave the seven angels seven golden bowls full of the wrath of God who lives for ever and ever, and the Temple was filled with smoke from the glory of God and from His power, and no one could enter the Temple until the seven plagues of the seven angels were ended.

Then I heard a loud voice from the Temple telling the seven angels, "Go and pour out on the Earth the seven bowls of the wrath of God."

Revelation 15.2-4

And I saw what appeared to be a sea of glass mingled with fire, and those who had conquered the beast and its image and the number of its name, standing beside the sea of glass with harps of God in their hands.

And they sing the song of Moses, the servant of God, and the song of the Lamb, saying:

Great and wonderful are thy deeds,
O Lord God Almighty!
Just and true are your ways,
O King of the ages!

Who shall not fear and glorify they name, O Lord?
For thou alone are holy.
All nations shall come and worship thee,
for thy judgements have been revealed.

Revelation 15.1

Then I saw another great portent in heaven, great and wonderful, seven angels with seven plagues, which are the last, for with them the wrath of God is ended.

Revelation 14.17->

And another angel came out of the Temple in Heaven, and he too had a sharp sickle. Then another angel came out from the altar, the angel who has power over fire, and he called with a loud voice to the one with the sharp sickle, "Put in your sickle, and gather the clusters of the vine of the Earth, for its grapes are ripe."

So the angel swung his sickle on the Earth and gathered the vintage of the Earth, and threw it into the great wine press of the wrath of God.

And the the wine press was trodden outside the city, and blood flowed from the wine press, as high as a horse's bridle, for one thousand six hundred miles.

Revelation 14.13-16

And I heard a voice from heaven saying, "Write this: Blessed are the dead who die in the Lord henceforth"

"Blessed indeed," says the Spirit, "that they may rest from their labors, for their deeds follow them."

Then I looked, and lo, a white cloud, and seated on the cloud one like a son of Adam with a golden crown on his head, and a sharp sickle in his hand. And another angel came out of the temple, calling with a loud voice to him who sat upon the cloud, "Put in your sickle and reap, for the harvest of the Earth is fully ripe." So he who sat upon the cloud swung his sickle on the Earth, and the Earth was reaped.

Revelation 13.9-12

And another angel, a third, followed them, saying with a loud voice, "If any one worships the beast and its image, and receives a mark on his forehead or on his hand, he also shall drink the wine of God's wrath, poured unmixed into the cup of his anger, and he shall be tormented with fire and sulphur in the presence of the holy angels and in the presence of the Lamb. And the smoke of their torment goes up for ever and ever; and they have no rest, day or night, these worshippers of the beast and its image, and whoever receives the mark of its name."

Here is a call for the endurance of the saints, those who keep the commandments of God and the faith of Jesus.
