Well, folks, in Joel 3, we learn that the Lord's army is coming to judge Judah and Jerusalem for their sins. It's gonna be a wild ride, with the Lord calling on all nations to gather in the Valley of Jehoshaphat to witness the judgment. Then all the nations are gonna be judged for what they've done to Israel - and it ain't gonna be pretty! So if you're a nation that's done some wrong to Israel, you better watch out. Yikes!
