Anger is an emotional response to a felt offense. It is an emotion, not sin. But uncontrolled anger can result in sin. Submit your anger to the Spirit of Christ. Allow Him to rein it in. This is not stuffing it, but allowing the Spirit to help you control it, so that the offense is properly confronted. Two cautions: 1) Deal with anger urgently within 24 hours “do not let the sun go down,” and 2) Be aware that Satan is looking for an opportunity to insert himself into your relationships through your uncontrolled anger. Properly dealt with, anger can actually energize you to address a needed relational problem.
