The moon is a major celestial body which orbits around the Earth every 30 days. The book of Genesis in the Bible calls it "the lesser light" which God had created in the beginning when He created the heavens and the earth.
In the Left Behind books, the moon is an important element in some of the judgments that God had poured out on mankind during the Tribulation. In the sixth Seal Judgment, the moon turned red as blood while the sun turned black as sackcloth. In the fourth Trumpet Judgment, the moon's light is diminished by a third of its usual brightness, which coincided with that of sun's light and heat that caused temperatures to plummet. Near the time of the Glorious Appearing, both the sun and the moon stopped shining in the sky.
