A servant of the Lord says the truth only

1 Kings 22:1-14
King of Israel wanted to retake the Ramoth Gilead from the king of Aram. Jehoshaphat king of Judah went down to see the king of Israel. So king of Israel invited Jehoshaphat go with him, Jehoshaphat agreed it, but he asked to seek the counsel of the Lord first.
400 prophets said "Go, for the Lord will give it into the king's hand."
Jehoshaphat asked "Is there not a prophet of the Lord here whom we can inquire of?"
The king of Israel hated him because he never prophesies anything good about him, but always bad. He is Micaiah son of Imlah.
Micaiah said "As surely as the Lord lives, I can tell him only what the Lord tells me." The messenger who had gone to summon Micaiah said to him " Said the word agree with other prophets and speak favorable."
Why?
King Aram had promised king of Israel return the cities his father took from Israel. Aram seems did not return these cities to Israel, so king of Israel wanted to retake it back.
Ahab thought together the force with Judah could be victorious.
King of Israel does evil things so the prophet of the Lord wouldn't say good things to him, but bad.
Jehoshaphat obeyed the commands of the Lord so the Lord blessed him, but he cooperated with the king of Israel is not wise decision. Might be the Lord let king of Judah came to visit Israel, let Ahab die for his won sin on the battle.
A servant of the Lord speaks the words of the Lord only. Only the words of truth will come true. Words of the Lord are the truth.
How?
The words in the bible are the truth in this world. Follow the spirit of the Lord and obey the words of the Lord will never be forsake and be blessed.
