I saw another angel flying in the midst of heaven, having the everlasting gospel to preach to those who dwell on the earth--to every nation, tribe, tongue, and people--saying with a loud voice, "Fear God and give glory to Him, for the hour of His judgment has come; and worship Him who made heaven and earth, the sea and springs of water."--Revelation 14:6-7
I saw that the strong hand of the enemy is set against the work of God, and the help and strength of every one who loves the cause of truth should be enlisted and great interest manifested by them to uphold the hands of those who advocate the truth and to take a course to shut out the enemy and weaken his power....
I then saw the third angel. Said my accompanying angel, "Fearful is his word, awful is his mission. He is the angel that is to select the wheat from the tares, and seal or bind the wheat for the heavenly garner." These things should engage the whole mind, the whole attention.
Again I was shown the necessity of those who believe we are having the last message of mercy being separate from those who are daily receiving or imbibing new error. I saw that neither young or old should attend the assemblies of those who are in error and darkness. Said the angel, "Let the mind cease to dwell on things of no profit." (Manuscript 3, July 2, 1853)
There is to be a turning and an overturning; but our work is not to stop. We are to instruct and enlighten those who have not heard the truth for this time....
At this crisis all are called upon to take their position. We must stand apart from those who are determined to make shipwreck of the faith. We must not sell our Lord at any price. We are to refuse to listen to the sophistries that have been brought in to make of no effect the truth for this time. Not a stone is to be moved in the foundation of this truth--not a pillar moved. (Letter 237, July 14, 1904)
REFLECTION: This message 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,...but the actual proclamation of the gospel is performed by the servants of Christ upon the earth. (The Great Controversy, 312)
