One episode of anger can damage a relationship of kindness and patience that took years to build. We are too quick to find excuses for our anger. The Bible clearly condemns sinful anger. It is sinful when it is in excess. It is sinful when it is expressed in ways that are harmful.
Anger brings out the worst in people.
It can turn us into vicious animals. All anger is not sinful. The manner in which we express it determines whether it is sinful. We must learn to have control of our anger, rather than letting anger get control of us. Do not let the sun go down on your wrath.
