Then I saw another angel flying in midheaven, with an eternal gospel to proclaim to those who live on the earth—to every nation and tribe and language and people.
References for Revelation 14:6
He said in a loud voice, "Fear God and give him glory, for the hour of his judgment has come; and worship him who made heaven and earth, the sea and the springs of water."
Then another angel, a second, followed, saying, "Fallen, fallen is Babylon the great! She has made all nations drink of the wine of the wrath of her fornication."
Then another angel, a third, followed them, crying with a loud voice, "Those who worship the beast and its image, and receive a mark on their foreheads or on their hands,
they will also drink the wine of God's wrath, poured unmixed into the cup of his anger, and they will be tormented with fire and sulfur in the presence of the holy angels and in the presence of the Lamb.
And the smoke of their torment goes up forever and ever. There is no rest day or night for those who worship the beast and its image and for anyone who receives the mark of its name."
Here is a call for the endurance of the saints, those who keep the commandments of God and hold fast to the faith of Jesus.
References for Revelation 14:12
And I heard a voice from heaven saying, "Write this: Blessed are the dead who from now on die in the Lord." "Yes," says the Spirit, "they will rest from their labors, for their deeds follow them."
Then I looked, and there was a white cloud, and seated on the cloud was one like the Son of Man, with a golden crown on his head, and a sharp sickle in his hand!
Another angel came out of the temple, calling with a loud voice to the one who sat on the cloud, "Use your sickle and reap, for the hour to reap has come, because the harvest of the earth is fully ripe."
So the one who sat on the cloud swung his sickle over the earth, and the earth was reaped.
Then 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 authority over fire, and he called with a loud voice to him who had the sharp sickle, "Use your sharp sickle and gather the clusters of the vine of the earth, for its grapes are ripe."
So the angel swung his sickle over the earth and gathered the vintage of the earth, and he threw it into the great wine press of the wrath of God.
And the wine press was trodden outside the city, and blood flowed from the wine press, as high as a horse's bridle, for a distance of about two hundred miles.
