I read this book years ago. Incredible. But now, there's a second edition that includes commentary from Joel Swokowski. The book, which was fantastic before, is even better now!
I especially loved the chapters on Love, Love Applications, Marriage and Marriage Applications. If only every couple considering marriage would find understanding from what the author is teaching. But, I would not suggest anyone read these chapters without first reading the entire book prior to these chapters. It's foundational. Understanding the main doctrines of Christianity in a non-contradictory way, is vital to fully understanding my favorite chapters.
Highly recommend!
