Doing by the wisdom of Spirit

2 Kings 10:1-35
Jehu let the guardian of Ahab's children killed them by two letters. First one asked them chose the est and most worthy of their master's son's and set him on his father's throne. Then fight for his father's home. But they were terrified and said "IF tow kings could not resist him, how can we? So both of them agreed to do whatever Jehu think best." The second letter, Jehu asked them killed Ahab's sons.
Jehu was acting deceptively in order to destroy the ministers of Baa; and he destroyed Baal worship in Israel. However, he did not turn away from the sins which he had caused Israel to commit- the worship of the golden calves at Bethel and Dem.
The Lord said to Jehu, "Because you have done well in accomplishing what is right in my eyes and have done to the house of Ahab all I has in mind to do. Your descendants will sit on the throne of Israel to the fourth generation."
The time that Jehu reigned over Israel in Samaria was 28 years.
Why?
Jehu has little forces to face group & families of Ahab, but he had wisdom let someone worked for him.
Jehu was smart and acted deceptively to kill all of the ministers of Baal.
To accomplish the commands of the Lord need wisdom of Spirit. Let it worked easy and efficient.
How?
Dear Lord, Please remind me, Let me do anything by the  wisdom of Spirit instead of by my own flesh.
