The answer is: A stone like a great millstone

Rev 18 vs 21

When diving into the Book of Revelation, it’s easy to get lost in the intense imagery, but let’s take a closer look at that “great millstone” tossed into the sea, shall we? This fiery finale is not just a dramatic climax but a powerful symbol of God’s judgment and the ultimate downfall of Babylon—a representation of oppression and moral decay. Speaking of millstones, did you know they were essential tools in the ancient world? They crushed grains into flour that fed families and communities! So, the idea of a millstone sinking into the sea captures the weight of loss and sorrow for a civilization built on vice.

Revelation often weaves together echoes of Old Testament texts, intensifying its meaning. For instance, in Jeremiah 51:63-64, the destruction of Babylon is also portrayed in dramatic imagery similar to the millstone—emphasizing the totality of judgment. Millstones weren’t just objects of inconvenience; they were vital for life, hence the vivid metaphor suggests that the fall of Babylon marks the end of a corrupt way of life.

Fun fact: In the Bible, millstones are mentioned in a cautionary sense too. Matthew 18:6 warns against leading others astray, suggesting that a heavy millstone hung around a neck would be preferable to causing harm to “little ones.” So here, this symbolism rounds up not just the fall of a city, but mirrors a deeper caution: good actions are rewarding, while negative consequences arise for evil—Old meets New Testament in such a relatable way, doesn’t it?
