More than a library filler
Format: Hardcover
Wayne Grudem’s Christian Ethics is a thorough guide for thinking through real life moral questions from a clear biblical perspective. I originally bought this book because I thought it would look good for a display of books. I was pleasantly surprised as I began to read it. The book is detailed and the chapters are laid out in a way that makes it easy to dip into specific topics as needed, which is helpful for pastors, teachers, and laypeople alike. I especially appreciate how Grudem consistently grounds his arguments in Scripture and explains how he reaches his conclusions. His writing is clear, practical, and often pastoral in tone, rather than academic. If you are looking for a comprehensive, conservative evangelical resource on Christian ethics that takes the authority of the Bible seriously and applies it to a wide range of modern issues, this book is a valuable addition to your library...not just a decoration piece.

This Book Will Strengthen Your Faith and Answer Hard Questions
Format: Hardcover
This book is a must read for all Christians. You don’t have to be a student of theology to appreciate the lessons inside. It’s actually strengthened my faith and answered many questions when it comes to how a Christian should apply the Scriptures to living an ethical life. It is a large textbook but it reads very well and if you want to truly dive deeper to live a more Christ like life I would highly encourage you to read it.
