Do the mission of a servant of God

2 Kings 9:1-13
Elisha summoned a man from company of the prophets and said to him, "Tuck your cloak into your belt, take this flask of oil with you and go to Ramoth Gilead. When you get there, look for Jehu son of Jehoshaphat. Go to him get him away from his companions and take him into an inner room. Then take the flask and pour the oil on his head and declare"This is what the Lord says: I anoint you king over Israel.' Then open the door and run; don't delay!"
The young man did as Elisha said, and he said to Jehu, "This is what the Lord, the God of Israel, says" "You are to destroy the house of Ahab your master, and I will avenge the blood of my servants the prophets and the blood of all the Lord's servants shed by Jezebel...."
Jehu disguised nothing happen after he was anointed, other fellow officer didn't belive, he told them what the Lord says. They hurried and took their cloaks and spread them under him on the bare steps. Then they blew the trumpt and shouted,"Jehu is king!"
The writer returns to the history of the kings which has been interrupted by the stories of Elisha.
Why?
The words of prophet of the Lord with power, so the officers committed Jehu as a new king over Israel.
Jehu will be king of Israel and he will avenge the blood of God's servant and the blood of all the Lord's servant shed by Jezebel has been revealed to Elijah in 1 Kings.
The prophet is declare the messages of the Lord, do not stay there wait for any prophet for anyone, the gift will be provided fro the Lord.
How?
To be a christian, we help or pray for others or doing gospel mission are not for any benefit from man, but response the love of the Lord on us.
