The "third angel's message" is a central theme in Ellen G. White's writings and refers to the message found in Revelation 14, which is understood by Seventh-day Adventists as a warning and a call to faithfulness in the last days. Here are key points from Ellen White's books: - The third angel, flying in the midst of heaven and heralding the commandments of God and the testimony of Jesus, represents the work of God's people. This message grows in strength and power until the whole earth is lightened with its glory. (LS 111.3; 5T 383.2) - The third angel's message is a warning of the coming hour of temptation and anguish, urging God's people to remain steadfast, even at the risk of their lives. It closes with the call: “Here is the patience of the saints: here are they that keep the commandments of God, and the faith of Jesus.” (EW 254) - When Christ entered the most holy place of the heavenly sanctuary, He committed to His servants the last message of mercy to be given to the world—this is the third angel's message. (4SP 273) - The message is to be proclaimed with great power, and as it swells into a loud cry, the earth will be filled with the glory of God. (8T 118.2; 7T 17.1) - The third angel's message is the great testing truth for this time and should be taught in all institutions, preparing people for the last days. (6T 128.1) - The angels in Revelation symbolize God's people, enlightened by the Spirit, proclaiming these messages to the world. (LS 429.1) - The message is to be given with power and clarity, especially emphasizing the Sabbath as the great test for this time. (6T 60) - The purpose of the third angel's message is to prepare a people to stand in the days of peril ahead. (8T 94.1) In summary, the third angel's message is a warning and a call to keep God's commandments and the faith of Jesus, preparing people for the final events of earth's history. It is to be proclaimed with increasing power and clarity until the whole world is illuminated with its truth.
