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.
When speaking of anger, the scripture uses descriptive terms that could equally be applied to the truths concerning fire. In doing so, the Bible makes a connection that can help believers gain a better understanding of the benefits or dangers of anger. According to scripture, anger can be kindled, a term used to describe the starting of a fire (Exodus 4:14; Numbers 11:1; Deuteronomy 32:22; Jeremiah 15:14), either a little (Psalm 2:12) or greatly (Numbers 11:10; 1 Samuel 11:6). The Bible also describes anger as waxing hot (Exodus 32:19), another connection to fire. These similarities are by divine design. As is true concerning fire, anger can be useful and productive, but it can also be destructive and harmful, especially when it gets out of control.
