Revelation 6:15-16

The reaction of every category of humanity all over the world is amazing. It indicates that people’s perception of God and the Lamb in heaven will be far more terrifying to them than the physical consequences of this judgment. Whereas the martyrs cry, "Avenge us" (Revelation 6:10), these unbelievers cry, "Hide us."

"What sinners dread most is not death, but having to stand before a holy and righteous God." [Note: Ibid., p. 456. Cf. Swete, p. 94.]

Literal interpretation does not rule out the use of hyperbole, which appears at this point. If all the mountains moved out of their places, there would be no places for people to seek to hide.
