Anger rarely stays inside the moment that caused it. A hard exchange at work can follow a man through the front door, while an old hurt at home can shape the tone of an entire evening. Paul does not pretend that anger is simple, nor does he give it permission to take charge. He calls believers to deal honestly and promptly with what has stirred them, before resentment settles in and begins making decisions of its own. The question is not whether you ever feel angry, but what you allow that anger to become.
