100-Pound Hailstones

The plagues, judgments, and disasters in the Book of Revelation and in other biblically prophetic passages are not understood by some as literally descriptive of miraculous events that God will bring one day upon mankind.

Such approaches have a difficult time accepting the fact that God will actually throw 100 pound hailstones at mankind during a future tribulation judgment.
