What does the wine vat analogy teach about God's judgment at Armageddon?
The wine vat analogy teaches that at Armageddon God gathers the world's armies into the Middle East, especially the valley of Megiddo, and destroys them like grapes trampled in a wine vat. The resulting blood flows as a river, deep as horses' bridles, showing the completeness of divine judgment.
Les teaches that the wine vat analogy pictures God's final judgment at Armageddon. The armies of the world gather into the land of Israel, and Satan thinks he can finally get rid of the Jewish problem, not realizing it will become the final battle between himself and Almighty God. God destroys those accumulated armies with a tremendous hailstorm of hundred-pound hailstones. Scripture uses the analogy of bringing grapes into a wine vat: as a person walking in the wine vat gets splattered with grape juice, so God will bring all the nations' armies to the Middle East, pack them primarily into the valley of Megiddo, and liken them to a wine vat. They are destroyed there with that final judgment of hundred-pound hailstones, accompanied by a river of blood and water that runs as deep as the bridles and horses' bits. Revelation 18 then gives the full view of how the whole world system will finally come to its end.
