533. How else does the Bible understand “death”?

The Bible also uses the term “death” to describe a power opposed to God, which threatens and seeks to destroy both physical and spiritual life. Thus the Revelation of Jesus Christ figuratively describes death as a person: “So I looked, and behold, a pale horse. And the name of him who sat on it was Death, and Hades followed with him” (Revelation 6: 8).
