The earth to be filled with knowledge of salvation—The prophecies in the eighteenth of Revelation will soon be fulfilled. During the proclamation of the third angel’s message, “another angel” is to “come down from heaven, having great power;” and the earth is to be “lightened with his glory.” [Verse 1.] The Spirit of the Lord will so graciously and universally bless consecrated human instrumentalities, that men, women, and children will open their lips in praise and testimony, filling the earth with the knowledge of God, and with His unsurpassed glory, as the waters cover the sea.3AM 135.3

Those who have held the beginning of their confidence firm unto the end will be wide-awake during the time that the third angel’s message is proclaimed with great power. During the loud cry, the church, aided by the providential interpositions of her exalted Lord, will diffuse the knowledge of salvation so abundantly that light shall be communicated to every city and town. The earth will be filled with the knowledge of salvation. So abundantly will the renewing Spirit of God have crowned with success the intensely active agencies, that the light of present truth will be seen flashing everywhere.—Manuscript 122, 1903 (October 9) (The Publishing Ministry, 388)3AM 136.1

Represents the voice of God’s people—John saw “Another angel come down from heaven, having great power; and the whole earth was lightened with his glory.” Revelation 18:1. That work is the voice of the people of God proclaiming a message of warning to the world. Has God, through John, given us light relating to the things which are to transpire in the remnant of time just at the end? Then with pen and voice we are to proclaim that very message to the world, not in a tame, indistinct whisper.—Manuscript 40, 1890 (November 3)3AM 136.2

Angel of Revelation 18 unites with the third angel—The third angel’s message is to be given with power. The power of the proclamation of the first and second messages is to be intensified in the third. In the Revelation John says of the heavenly messenger who unites with the third angel: “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.” Revelation 18:1, 2. We are in danger of giving the third angel’s message in so indefinite a manner that it does not impress the people. So many other interests are brought in that the very message which should be proclaimed with power becomes tame and voiceless.—Testimonies for the Church 6:60 (1901)3AM 136.3

The third angel’s message increases in strength and power—The third angel, flying in the midst of heaven and heralding the commandments of God and the testimony of Jesus, represents our work. The message loses none of its force in the angel’s onward flight, for John sees it increasing in strength and power until the whole earth is lightened with its glory. The course of God’s commandment-keeping people is onward, ever onward. The message of truth that we bear must go to nations, tongues, and peoples. Soon it will go with a loud voice, and the earth will be lightened with its glory. Are we preparing for this great outpouring of the Spirit of God?—Testimonies for the Church 5:383 (1885)3AM 137.1

We have a mighty work to do—The third angel’s message must go over the land, and awaken the people, and call their attention to the commandments of God and the faith of Jesus. Another angel unites his voice with the third angel, and the earth is lighted with its glory. The light increases, and it shines out to all the nations of the earth. It is to go forth as a light that burneth. It will be attended with great power, until its golden beams have fallen upon every tongue, every people, and every nation upon the face of the whole earth. Let me ask you, What you are doing to prepare for this work? Are you building for eternity? You must remember that this angel represents the people that have this message to give to the world. Are you among that people? Do you really believe that this work in which we are engaged is truly the third angel’s message? If so, then you understand that we have a mighty work to do, and that we ought to be about it.—The Review and Herald, August 18, 18853AM 137.2

Publishing houses largely involved—In a large degree through our publishing houses is to be accomplished the work of that other angel who comes down from heaven with great power and who lightens the earth with his glory.—Testimonies for the Church 7:140 (1902)3AM 138.1

God uses only those who seek and accept every ray of light—It is to the thirsting soul that the fountain of living waters is open. God declares: “I will pour water upon him that is thirsty, and floods upon the dry ground.” To souls that are earnestly seeking for light and that accept with gladness every ray of divine illumination from His holy word, to such alone light will be given. It is through these souls that God will reveal that light and power which will lighten the whole earth with His glory.—Testimonies for the Church 5:729 (1889)3AM 138.2

God has agents among the rulers who will receive the message—Some, I saw, have a prejudice against our rulers and laws; but if it were not for law, this world would be in an awful condition. God restrains our rulers; for the hearts of all are in His hands. Bounds are set, beyond which they cannot go. Many of the rulers are those whom Satan controls; but I saw that God has His agents, even among the rulers. And some of them will yet be converted to the truth. They are now acting the part that God would have them. When Satan works through his agents, propositions are made, that, if carried out, would impede the work of God and produce great evil. The good angels move upon these agents of God to oppose such propositions with strong reasons, which Satan’s agents cannot resist. A few of God’s agents will have power to bear down a great mass of evil. Thus the work will go on until the third message has done its work, and at the loud cry of the third angel, these agents will have an opportunity to receive the truth, and some of them will be converted, and endure with the saints through the time of trouble. When Jesus leaves the most holy, His restraining Spirit is withdrawn from rulers and people. They are left to the control of evil angels. Then such laws will be made by the counsel and direction of Satan, that unless time should be very short, no flesh could be saved.—Testimonies for the Church 1:203, 204 (1859)3AM 138.3

Present the truth in no measured terms—The eighteenth chapter of Revelation reveals the importance of presenting the truth in no measured terms, but with boldness and power. There must be no toning down of the truth, no muffling of the message for this time. Satan has devised a state of things whereby the proclamation of the third angel’s message shall be bound about. We must beware of his plans and methods. The third angel’s message is to be strengthened and confirmed.—Letter 28, 1900 (February 17)3AM 139.1

No specific time for outpouring revealed—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.—The Review and Herald, March 29, 18923AM 139.2

Special light may come in unexpected ways—I stated that ... there was to be special light for God’s people as they neared the closing scenes of this earth’s history. Another angel was to come from heaven with a message, and the whole earth was to be lightened with his glory. It would be impossible for us to state just how this additional light would come. It might come in a very unexpected manner, in a way that would not agree with the ideas that many have conceived. It is not at all untimely or contrary to the ways and works of God to send light to His people in unexpected ways.—Letter 22, 1889 (January 18)3AM 140.1

God will take the reins using uncommon ways and means—Let me tell you that the Lord will work in this last work in a manner very much out of the common order of things, and in a way that will be contrary to any human planning. There will be those among us who will always want to control the work of God, to dictate even what movements shall be made when the work goes forward under the direction of the angel who joins the third angel in the message to be given to the world. God will use ways and means by which it will be seen that He is taking the reins in His own hands. The workers will be surprised by the simple means that God will use to bring about and perfect His work of righteousness. Those who are accounted good workers will need to draw nigh to God. They will need the divine touch. They will need to drink more deeply and continuously at the fountain of living water in order that they may discern God’s work at every point. Workers may make mistakes, but you should give them a chance to correct their errors, give them an opportunity to learn caution by leaving the work in their hands.—Letter 5, 1885 (October 31) (Testimonies to Ministers and Gospel Workers, 300)3AM 140.2

Events of Pentecost repeated with greater power—It is with an earnest longing that I look forward to the time when the events of the day of Pentecost shall be repeated with even greater power than on that occasion. John says, “I saw another angel come down from heaven, having great power; and the earth was lightened with his glory.” Then, as at the Pentecostal season, the people will hear the truth spoken to them, every man in his own tongue. God can breathe new life into every soul that sincerely desires to serve Him, and can touch the lips with a live coal from off the altar, and cause them to become eloquent with His praise. Thousands of voices will be imbued with the power to speak forth the wonderful truths of God’s word. The stammering tongue will be unloosed, and the timid will be made strong to bear courageous testimony to the truth. May the Lord help His people to cleanse the soul temple from every defilement, and to maintain such a close connection with Him that they may be partakers of the latter rain when it shall be poured out.—The Review and Herald, July 20, 18863AM 141.1
