Anger causes us to be moody and mean. It destroys in a moment what it took years to build. We lose our cool and without thinking, blow all the good will that has been built up between us and a neighbor. Anger gets to be a habit. Angry people subject those around them to a constant flow of wrath, harsh words, threats, even violence. Others choose the passive-aggressive route. Through silence and sulking, they punish the one with whom they are angry by withholding themselves from them. Still others turn their anger inward and live lives of depression and anxiety.
But before we give anger a bad rap, recognize that it is a natural reaction. All of the natural reactions God created in us are good. Anger itself is not sin. So Paul wrote in Ephesians 4:26, "Be ye angry, and sin not." He didn't say not to get angry, but not to sin when we are angry. Anger usually is an emotional reaction that comes in the fact of some perceived wrong doing. It is a signal telling us something is not right. It comes from our need for self-protections. Anger is not wrong in itself. It is the way we use, or express it, that is right or wrong.
Ever heard the phrase, "Good and angry?" The problem is, when most people are good and angry, they are very angry, but not very good. You are not bad because you feel anger. But anger, even when it is justified, does not excuse destructive behavior. Let anger do its proper job. Let it motivate you to stand up against wrong doing, unfairness, injustice. Just be sure you control your anger, rather than letting it control you.
