The writers discuss four principles necessary to any healthy relationship: integrity, love, humility, and forgiveness. Whether an intimate marriage relationship or a casual working relationship, these "ingredients" are the key to success. The writers show these principles lived out in the Christian life as true mandates from God. The first few chapters discuss our longing for whole relationships, the divine roots of our relational nature, how God expresses His relationship with us, and how we can reflect that in our own lives. The rest of the book is devoted to discussing each principle individually and to giving examples on the results of putting them into practice, or the consequences of not putting them into practice.What is different about this relationship book than the others out there? Well, from my own reading experience, this particular book talks more about relationships in general, not just marriage. It could make a great gift for a pastor, business leader, or husband/father. I think the tone and style is geared toward men, in my opinion. There's no "mushy" stuff or romantic ideas -- just straightforward advice for maintaining Christ-like characteristics in your daily interactions with others.There are discussion questions included at the end of each chapter, so this could be used in a small group or Bible study setting.
