If you're in relationships you're going to be in conflict. My goal is to make peace with whoever I'm in conflict with. If you're a peacemaker then you're a son of God (Matthew 5:9). Disagreement with someone does not mean misalignment with someone. I can disagree with my wife but I'm still in union with her. I can disagree with my boss end it doesn't mean I'm not unified with my organization. A peacemaker's goal at the end of the day is reconciliation because a son values his family. So confront your bad attitude before it becomes a bad behavior leading to bad fight.
In most conflicts we are trying to "be right" but it's more important to "do right." So if you are at odds with someone go make it right then proving you were right. As a matter fact God says He values your right relationship with someone else more than your worship (Matthew 5:23-24). Your community matters to God more than you think. Forgiving quickly and often is one of the most potent ways to show others Christianity really works. Let your conflict be an invitation to cultivate a deeper community with those around you and not an excuse to dissolve your community.
