2 Kings 10:30 The Wars of Jehu:
The LORD said to Jehu, "Because you have done well in executing what is right in My eyes, and have done to the house of Ahab according to all that was in My heart, your sons of the fourth generation shall sit on the throne of Israel."
2 Kings 10:31 The Walk of Jehu:
But Jehu was not careful to walk in the law of the LORD, the God of Israel, with all his heart; he did not depart from the sins of Jeroboam, which he made Israel sin.
1 Corinthians 9:26-27 Paul's walk (running) and Paul's war (boxing):
Therefore I run in such a way, as not without aim;
I box in such a way, as not beating the air;
but I discipline my body and make it my slave, so that, after I have preached to others, I myself will not be disqualified.
Jehu almost became a good king. He could have been Israel's first and only good king. He warred well, but he disqualified himself by his walk (his daily life). I feel badly for the man. Coulda! Woulda! Shoulda! But he was not careful to walk in the Word of God.
Are you good at war? Are you a good Bible teacher, a good evangelist, a powerful leader, or a gifted counselor? Are you also careful to feed yourself the Bible every day; or are you careless about your own personal obedience? Many great workers for God have been disqualified because they were careless about their own holiness. It is heartbreaking, and it hurts the people who follow them.
In the New Testament, Paul teaches that Christian success depends on warring well (using your spiritual gift) but also walking in holiness. Paul did not want to be a good preacher and a bad "liver." He was heartbroken for men who warred for God but were unwilling to walk for God. He was concerned that he would follow their example and be disqualified.
Be careful. Win the war. Walk the walk. Do it all!
For me to live is Christ.
