For a fire is kindled in mine anger, and shall burn unto the lowest hell, and shall consume the earth with her increase, and set on fire the foundations of the mountains. Deuteronomy 32:22.
Every satanic agency is now at work with power from beneath. The day of death is not set before us in the Word as the great constraining motive impelling us to be wide awake and determined in improving our opportunities. What motive does God present in His Word to all His workers? ... “The great day of the Lord is near, it is near, and hasteth greatly” (Zephaniah 1:14). And before the coming of this last great day, we are to proclaim the last message of mercy to a fallen world, to prepare men and women for the Lord’s second coming.
Everything that can be devised by the enemy to occupy the mind, and to divert attention from this message, will be devised. But we are to go forward in the proclamation of the Word of the Lord.

They can walk through the fire, as Shadrach, Meshach, and Abednego walked in the midst of the furnace heated seven times hotter than it was wont to be heated. The Hebrew worthies could not be consumed, because the form of the fourth, the Son of God, was with them. So in the day of the coming of the Lord, smoke and flame will be powerless to harm the righteous. Those who are united with the Lord will escape unscathed. Earthquakes, hurricanes, flame, and flood cannot injure those who are prepared to meet their Saviour in peace. But those who rejected our Saviour, and scourged and crucified Him, will be among those who will be raised from the dead to behold His coming in the clouds of heaven, attended by the heavenly host—ten thousand times ten thousand, and thousands of thousands...
This scene has been presented before me as fully as I could bear to behold it. Then the scene has changed, and scenes of things existing at the present time have passed before me—Manuscript 159, September 4, 1903, “A Message to Leading Physicians.”
