Listen to the truth instead of good word

1 Kings 22:1-8
For three years there was no war betweeen Aram and Israel. But in the third year Jehoshaphat king of Judah went down to see the king of Israel. He said to the king of Israel, "Don't you know that Ramoth Gilead belongs to us and yet we are doing nothing to retake it from the king of Aram?"  There agree go together to fight against Ramoth Gilead.
Jehoshaphat replied to the king of Israel, "First seek the counsel of the Lord."
Four hundred men they answered, "for the Lord will give it into the king's hand." But Jehoshaphat asked, "it there not a prophet of the Lord here whom we can in quire of?" The king of Israel answered ,"There is still one through whom we can inquire of the Lord, but I hat him because he never prophesies anything good about me." Jehoshaphat is request which brings Micaiah to the king.
Jehoshaphat's son Jerom has married Ahab's daughter Athaliah. Israel and Judah are, temporarily, allies against Syria.
Why?
Jehoshaphat worship the Lord so he like to require the prophet of the Lord, who can say the truth.
Prophet or Christian should said the word of the Lord, the truth, but not the word of man who liked.
How?
How about me? Like to hear what I liked word or should listen to the truth. God's word always remind me and are good to me. Listen to the truth instead of the good words.
