Mark 13:25

And the stars shall be falling from heaven, and the powers that are in the heavens shall be shaken.

These words too are taken to be a strong metaphor for the fall of mighty princes and rulers; but, since it is a good rule of interpretation that the secondary fulfillment of prophecy greatly exceeds in scope and significance the first fulfillment; and since, in the first fulfillment of this chapter, many notable princes and rulers among both the Romans and the Jews fell, it is the conviction here that something far more is prophesied of the end of all things.

Regarding the quibble that "stars cannot fall," it need only be remarked that if our earth was suddenly blasted out of its orbit, they would certainly appear to fall. Moreover God has promised a second time to "shake" this earth in the sense of removing it (Hebrews 12:26). We should believe God's promise and construe the words here as a reference to cataclysmic future events incapable of description by finite men. In this connection, see 2 Peter 3:8-13. Bickersteth's comment is pertinent:

The powers may here mean those great unseen forces of nature by which the universe is held in equipoise. When the Creator wills it, these powers shall be shaken. "The pillars of heaven tremble" (Job 26:1); "And all the host of heaven shall be dissolved, and the heavens shall be rolled together as a scroll" (Isaiah 34:4). As the end of the world approaches, the elements will quiver and tremble.[43]
