Anger is not sinful, yet the source of one’s anger sometimes does manifest one’s sinful heart. Perhaps the prophet Jonah best demonstrates this truth. When the Lord first approached Jonah about the need in Nineveh, Jonah clearly displayed his displeasure in seeing the Lord work in the lives of the Ninevites. After experiencing the Lord’s chastening, Jonah appeared to have a heart change. Yet, it did not take long before his anger revealed his true feelings and thoughts. As the hearts of the Ninevites were becoming tender toward the Lord, the prophet’s heart was becoming hardened through anger. His anger revealed that he wanted his own will and not God’s.
The Lord blessed the throne of David and desired to do the same for his posterity. Because the Lord wanted to establish Solomon’s rule, He provided some guidelines for Solomon. One prominent issue involved Solomon following in his father’s footsteps by living with integrity of heart. Integrity is very much a matter of the heart. In fact, four times in scripture integrity is associated with the heart. Twice the Bible refers to the integrity of Abimelech’s heart (Genesis 20:5-6) and another two times it refers to the integrity of David’s heart (1 Kings 9:4; Psalm 78:72). Though these men had little else in common, both understood that integrity involved a matter of the heart. A lack of integrity is first and foremost a heart issue.
