Ignore the prophet when he says you're doing wrong

Making my way through the Old Testament, I laughed out loud at these verses in 1 Kings 22.

7 And Jehoshaphat said, Is there not here a prophet of the Lord besides, that we might enquire of him?
8 And the king of Israel said unto Jehoshaphat, There is yet one man, Micaiah the son of Imlah, by whom we may enquire of the Lord: but I hate him; for he doth not prophesy good concerning me, but evil.

And later on in the chapter, in fact Micaiah does prophesy that Ahab, the King of Israel, will die.  Ahab Dies.

Even when prophets say hard things, we should listen.
