When it comes to anger, there are natural dilemmas that exist when dealing with how you do or don't express it. Many people who have issues with anger do so because they feel, or the partner feels, that it's not okay to be angry. And because there is no allowed outlet provided for their upset, things build to an extreme point much more quickly than if there had been permission to experience and display negative emotions frustration, disappointment, etc.. The Bible states that In your anger do not sin, Ephesians 426a and, along these lines, one of the central concepts of conflict resolution is that it's okay to feel and express your upset as long as you do it appropriately - ideally, in a way that creates understanding, not does further damage. One of the primary purposes of this book is to not only show better ways to express potential upset, but how to maintain a healthy relationship where, if you follow the guidelines, discussions are unlikely to ever turn into fights.
