Who is the stone that smote the image, and what did it become?
The stone that smote the image is Christ at His Second Coming. When He comes, the iron, clay, brass, silver, and gold are broken to pieces and annihilated, and the stone becomes a great mountain, or a kingdom, that fills the whole earth.
Les explains that in the image, the previous empires—banking and interest, Greek culture, and the Roman system of law—are all incorporated into the final empire. But when Christ comes, the iron, clay, brass, silver, and gold are broken to pieces together and become like the chaff of the summer threshing floor, totally annihilated. The wind carries them away so no place is found for them. The stone, which is Christ at His Second Coming, smote the image and destroyed the world system, and it became a great mountain, or a kingdom, that fills the whole earth.
Forasmuch as thou sawest that the stone was cut out of the mountain without hands, and that it brake in pieces the iron, the brass, the clay, the silver, and the gold; the great God hath made known to the king what shall come to pass hereafter: and the dream is certain, and the interpretation thereof sure.
