WHAT DOES THE BIBLE SAY ABOUT ANGER?
Answer: Handling anger is an important life skill. Christian counselors report that 50 percent of people who come in for counseling have problems dealing with anger. Anger can shatter communication and tear apart relationships, and it ruins both the joy and health of many. Sadly, people tend to justify their anger instead of accepting responsibility for it. Everyone struggles, to varying degrees, with anger. Thankfully, God’s Word contains principles regarding how to handle anger in a godly manner, and how to overcome sinful anger.
Anger is not always sin. There is a type of anger of which the Bible approves, often called “righteous indignation.” God is angry (Psalm 7:11; Mark 3:5), and believers are commanded to be angry (Ephesians 4:26). Two Greek words in the New Testament are translated as “anger.” One means “passion, energy” and the other means “agitated, boiling.” Biblically, anger is God-given energy intended to help us solve problems. Examples of biblical anger include David’s being upset over hearing Nathan the prophet sharing an injustice (2 Samuel 12) and Jesus’ anger over how some of the Jews had defiled worship at God’s temple in Jerusalem (John 2:13-18). Notice that neither of these examples of anger involved self-defense, but a defense of others or of a principle.
That being said, it is important to recognize that anger at an injustice inflicted against oneself is also appropriate. Anger has been said to be a warning flag—it alerts us to those times when others are attempting to or have violated our boundaries. God cares for each individual. Sadly, we do not always stand up for one another, meaning that sometimes we must stand up for ourselves. This is especially important when considering the anger that victims often feel. Victims of abuse, violent crime, or the like have been violated in some way. Often while experiencing the trauma, they do not experience anger. Later, in working through the trauma, anger will emerge. For a victim to reach a place of true health and forgiveness, he or she must first accept the trauma for what it was. In order to fully accept that an act was unjust, one must sometimes experience anger. Because of the complexities of trauma recovery, this anger is often not short-lived, particularly for victims of abuse. Victims should process through their anger and come to a place of acceptance, even forgiveness. This is often a long journey. As God heals the victim, the victim’s emotions, including anger, will follow. Allowing the process to occur does not mean the person is living in sin. Read more here
