Revelation 18:1-4 - And after these things I saw another angel come down from heaven, having great power; and the earth was lightened with his glory. And he cried mightily with a strong voice, saying, Babylon the great is fallen, is fallen, and is become the habitation of devils, and the hold of every foul spirit, and a cage of every unclean and hateful bird. For all nations have drunk of the wine of the wrath of her fornication, and the kings of the earth have committed fornication with her, and the merchants of the earth are waxed rich through the abundance of her delicacies. And I heard another voice from heaven, saying, Come out of her, My people, that ye be not partakers of her sins, and that ye receive not of her plagues.
EW 277 - “I saw angels hurrying to and fro in heaven, descending to the earth, and again ascending to heaven, preparing for the fulfillment of some important event. Then I saw another mighty angel commissioned to descend to the earth, to unite his voice with the third angel, and give power and force to his message. Great power and glory were imparted to the angel, and as he descended, the earth was lightened with his glory. The light which attended this angel penetrated everywhere, as he cried mightily, with a strong voice, Babylon the great is fallen.”
GC 611 - “The angel who unites in the proclamation of the third angel’s message is to lighten the whole earth with his glory.”
1888 804 - “God has given the messages of Revelation 14 their place in the line of prophecy, and their work is not to cease till the close of this earth’s history. The first and second angel’s messages are still truth for this time, and are to run parallel with this which follows. The third angel proclaims his warning with a loud voice. ‘After these things,’ said John, ‘I saw another angel come down from heaven, having great power, and the earth was lightened with his glory’. (Rev 18:1). In this illumination, the light of all the three messages is combined.”
1SM 192 - I have no specific time of which to speak when the outpouring of the Holy Spirit will take place—when the mighty angel will come down from heaven, and unite with the third angel in closing up the work for this world; my message is that our only safety is in being ready for the heavenly refreshing, having our lamps trimmed and burning. Christ has told us to watch; “for in such an hour as ye think not, the Son of man cometh.” “Watch and pray” is the charge that is given us by our Redeemer. Day by day we are to seek the enlightenment of the Spirit of God, that it may do its office work upon the soul and character. O, how much time has been wasted through giving attention to trifling things. Repent and be converted, that your sins may be blotted out when the times of refreshing shall come from the presence of the Lord.
RH July 5, 1906 - “How comes the word that I have declared that New York is to be swept away by a tidal wave? This I have never said. I have said, as I looked at the great buildings going up there, story after story, ‘What terrible scenes will take place when the LORD shall arise to shake terribly the earth! Then the words of Revelation 18:1-3 will be fulfilled.’ The whole of the eighteenth chapter of Revelation is a warning of what is coming on the earth. But I have no light in particular in regard to what is coming on New York, only that I know that one day the great buildings there will be thrown down by the turning and overturning of God’s power. From the light given me, I know that destruction is in the world. One word from the LORD, one touch of his mighty power, and these massive structures will fall. Scenes will take place the fearfulness of which we can not imagine.”
