We have also a more sure word of prophecy; whereunto ye do well that ye take heed, as unto a light that shineth in a dark place, until the day dawn, and the day star arise in your hearts. 2 Peter 1:19. Mar 17.1
This message [Revelation 14:6, 7] is declared to be a part of “the everlasting gospel.” The work of preaching the gospel has not been committed to angels, but has been entrusted to men. Holy angels have been employed in directing this work, they have in charge the great movements for the salvation of men; but the actual proclamation of the gospel is performed by the servants of Christ upon the earth. Mar 17.2
Faithful men, who were obedient to the promptings of God's Spirit and the teachings of His word, were to proclaim this warning to the world. They were those who had taken heed to the “sure word of prophecy,” the “light that shineth in a dark place, until the day dawn, and the day star arise.” 2 Peter 1:19. They had been seeking the knowledge of God more than all hid treasures, counting it “better than the merchandise of silver, and the gain thereof than fine gold.” Proverbs 3:14. And the Lord revealed to them the great things of the kingdom. “The secret of the Lord is with them that fear him; and he will show them his covenant.” Psalm 25:14. Mar 17.3
It was not the scholarly theologians who had an understanding of this truth, and engaged in its proclamation. Had these been faithful watchmen, diligently and prayerfully searching the Scriptures, they would have known the time of night; the prophecies would have opened to them the events about to take place. But they did not occupy this position, and the message was given by humbler men. Said Jesus: “Walk while ye have the light, lest darkness come upon you.” John 12:35. Those who turn away from the light which God has given, or who neglect to seek it when it is within their reach, are left in darkness. But the Saviour declares: “He that followeth me shall not walk in darkness, but shall have the light of life.” John 8:12. Whoever is with singleness of purpose seeking to do God's will, earnestly heeding the light already given, will receive greater light; to that soul some star of heavenly radiance will be sent to guide him into all truth.12The Great Controversy, 312.
