The fourteenth chapter of Revelation is a chapter of the deepest interest. This scripture will soon be understood in all its bearings, and the messages given to John the revelator will be repeated with distinct utterance (The Review and Herald, October 13, 1904).

 Christ is coming the second time, with power unto salvation. To prepare human beings for this event, He has sent the first, second, and third angels’ messages. These angels represent those who receive the truth, and with power open the gospel to the world (Letter 79, 1900).

 The churches have become as described in the eighteenth chapter of Revelation. Why are the messages of Revelation fourteen given? Because the principles of the churches have become corrupted.... [Revelation 14:6-10 quoted.]
 Apparently the whole world is guilty of receiving the mark of the beast. But the prophet sees a company who are not worshiping the beast, and who have not received his mark in their foreheads or in their hands. “Here is the patience of the saints,” he declares; “here are they that keep the commandments of God, and the faith of Jesus” (Manuscript 92, 1904).

 The time of God’s destructive judgments is the time of mercy for those who have no opportunity to learn what is truth. Tenderly will the Lord look upon them. His heart of mercy is touched; His hand is still stretched out to save, while the door is closed to those who would not enter. Large numbers will be admitted who in these last days hear the truth for the first time (The Review and Herald, July 5, 1906).

 [Revelation 14:9, 10 quoted.] It is for the interest of all to understand what the mark of the beast is, and how they may escape the dread threatenings of God. Why are men not interested to know what constitutes the mark of the beast and his image? It is in direct contrast with the mark of God. [Exodus 31:12-17 quoted.]
 The Sabbath question will be the issue in the great conflict in which all the world will act a part. [Revelation 13:4-10 quoted.] This entire chapter is a revelation of what will surely take place [Revelation 13:11, 15-17 quoted] (Manuscript 88, 1897).

 John was called to behold a people distinct from those who worship the beast and his image by keeping the first day of the week. The observance of this day is the mark of the beast (Letter 31, 1898).

 The third angel’s message has been sent forth to the world, warning men against receiving the mark of the beast or of his image in their foreheads or in their hands. To receive this mark means to come to the same decision as the beast has done, and to advocate the same ideas, in direct opposition to the Word of God. Of all who receive this mark, God says, “The same shall drink of the wine of the wrath of God, which is poured out without mixture into the cup of his indignation; and he shall be tormented with fire and brimstone in the presence of the holy angels, and in the presence of the Lamb.” ...
 If the light of truth has been presented to you, revealing the Sabbath of the fourth commandment, and showing that there is no foundation in the Word of God for Sunday observance, and yet you still cling to the false sabbath, refusing to keep holy the Sabbath which God calls “My holy day,” you receive the mark of the beast. When does this take place? When you obey the decree that commands you to cease from labor on Sunday and worship God, while you know that there is not a word in the Bible showing Sunday to be other than a common working day, you consent to receive the mark of the beast, and refuse the seal of God.
 If we receive this mark in our foreheads or in our hands, the judgments pronounced against the disobedient must fall upon us. But the seal of the living God is placed upon those who conscientiously keep the Sabbath of the Lord (The Review and Herald, July 13, 1897).

 This message embraces the two preceding messages. It is represented as being given with a loud voice; that is, with the power of the Holy Spirit. Everything is now at stake. The third angel’s message is to be regarded as of the highest importance. It is a life and death question. The impression made by this message will be proportionate to the earnestness and solemnity with which it is proclaimed (Manuscript 16, 1900).

 In the issue of the great contest two parties are developed, those who “worship the beast and his image,” and receive his mark, and those who receive “the seal of the living God,” who have the “Father’s name written in their foreheads.” This is not a visible mark (The Signs of the Times, November 1, 1899).
 (Revelation 18:1-18; 2 Thessalonians 2:7-12.) Guard Against Mystery of Iniquity—The third angel’s message increases in importance as we near the close of this earth’s history....
 God has presented to me the dangers that are threatening those who have been given the sacred work of proclaiming the third angel’s message. They are to remember that this message is of the utmost consequence to the whole world. They need to search the Scriptures diligently, that they may learn how to guard against the mystery of iniquity, which plays so large a part in the closing scenes of this earth’s history.
 There will be more and still more external parade by worldly powers. Under different symbols, God presented to John the wicked character and seductive influence of those who have been distinguished for their persecution of His people. The eighteenth chapter of Revelation speaks of mystic Babylon, fallen from her high estate to become a persecuting power. Those who keep the commandments of God and have the faith of Jesus are the object of the wrath of this power [Revelation 18:1-8 quoted] (Manuscript 135, 1902).

 The work of the Holy Spirit is to convince the world of sin, of righteousness, and of judgment. The world can only be warned by seeing those who believe the truth sanctified through the truth, acting upon high and holy principles, showing in a high, elevated sense, the line of demarcation between those who keep the commandments of God and whose who trample them under their feet. The sanctification of the Spirit signalizes the difference between those who have the seal of God and those who keep a spurious rest day.
 When the test comes, it will be clearly shown what the mark of the beast is. It is the keeping of Sunday. Those who, after having heard the truth, continue to regard this day as holy bear the signature of the man of sin, who thought to change times and laws (Letter 12, 1900).

 The substitution of the false for the true is the last act in the drama. When this substitution becomes universal, God will reveal Himself. When the laws of men are exalted above the laws of God, when the powers of this earth try to force men to keep the first day of the week, know that the time has come for God to work. He will arise in His majesty, and will shake terribly the earth. He will come out of His place to punish the inhabitants of the world for their iniquity (The Review and Herald, April 23, 1901).
 (Revelation 19:1-4; Revelation 7:2, 3; Revelation 13:13, 16; Exodus 31:13-17; 2 Thessalonians 2:3, 4.) The Mark of Distinction—We are nearing the close of this earth’s history. Satan is making desperate efforts to make himself god, to speak and act like God, to appear as one who has a right to control the consciences of men. He strives with all his power to place a human institution in the position of God’s holy rest day. Under the jurisdiction of the man of sin, men have exalted a false standard in complete opposition to God’s enactment. Each Sabbath institution bears the name of its author, an ineffaceable mark showing the authority of each. The first day of the week has not one particle of sanctity. It is the production of the man of sin, who strives in this way to counterwork God’s purposes.
 God has designated the seventh day as His Sabbath. [Exodus 31:13, 17, 16 quoted.]
 Thus the distinction is drawn between the loyal and the disloyal. Those who desire to have the seal of God in their foreheads must keep the Sabbath of the fourth commandment. Thus they are distinguished from the disloyal, who have accepted a manmade institution in place of the true Sabbath. The observance of God’s rest day is a mark of distinction between him that serveth God and him that serveth Him not (The Review and Herald, April 23, 1901).
