And Jehoshaphat said to the king of Israel, “Inquire first for the word of the Lord.” Then the king of Israel gathered the prophets together, about four hundred men, and said to them, “Shall I go to battle against Ramoth-gilead, or shall I refrain?” And they said, “Go up, for the Lord will give it into the hand of the king.” But Jehoshaphat said, “Is there not here another prophet of the Lord of whom we may inquire?” And the king of Israel said to Jehoshaphat, “There is yet one man by whom we may inquire of the Lord, Micaiah the son of Imlah, but I hate him, for he never prophesies good concerning me, but evil.” And Jehoshaphat said, “Let not the king say so.” Then the king of Israel summoned an officer and said, “Bring quickly Micaiah the son of Imlah.” Now the king of Israel and Jehoshaphat the king of Judah were sitting on their thrones, arrayed in their robes, at the threshing floor at the entrance of the gate of Samaria, and all the prophets were prophesying before them. And Zedekiah the son of Chenaanah made for himself horns of iron and said, “Thus says the Lord, ‘With these you shall push the Syrians until they are destroyed.’” And all the prophets prophesied so and said, “Go up to Ramoth-gilead and triumph; the Lord will give it into the hand of the king.” 1 Kings 22:5-12.
Jehoshaphat, who actually walks in God’s ways, knows a bunch of liars when he hears them. He’d like a second opinion. Ahab knows a guy, Micaiah, but he hates him because he brings bad news.
What Micaiah is actually good news if Ahab would heed the warning. What the 400 false prophets are saying, even though it’s all sunshine and rainbows, is actually bad news because it tricks him into harm’s way.
The Gospel is like this today. Believe in Christ and forsake your life to gain eternity. Or, believe one of the four hundred lies that you can escape judgment another way, and be lost forever.
