Christ in His Sanctuary : Chapter 6 - The End of the 2300 Days

A great religious awakening under the proclamation of Christ's soon coming is foretold in the prophecy of the first angel's message of Revelation 14. An angel is seen flying “in the midst of heaven, having the everlasting gospel to preach unto them that dwell on the earth, and to every nation, and kindred, and tongue, and people.” “With a loud voice” he proclaims the message: “Fear God, and give glory to Him; for the hour of His judgment is come: and worship Him that made heaven, and earth, and the sea, and the fountains of waters.” Verses 6, 7.

In different lands there were isolated bodies of Christians who, solely by the study of the Scriptures, arrived at the belief that the Saviour's advent was near....
To William Miller and his colaborers it was given to preach the warning in America. This country became the center of the great advent movement. It was here that the prophecy of the first angel's message had its most direct fulfillment. The writings of Miller and his associates were carried to distant lands. Wherever missionaries had penetrated in all the world, were sent the glad tidings of Christ's speedy return. Far and wide spread the message of the everlasting gospel: “Fear God, and give glory to Him; for the hour of His judgment is come.”...
