I love this book by Lewis Sperry Chafer, revised by John Walvoord. The original book featured 49 chapters, and this current book has been revised and features 52 chapters. A great theology book for personal or group study. 52 chapters are great for a weekly study for one year. I have given this book to Christians, providing them the basics of theology. For further study I would recommend Basic Theology by Charles Ryrie, and if you have additional funds purchase Systematic Theology (4 volumes) by Lewis Sperry Chafer. These three I have in my library, and I enjoy each one of them. I highly recommend that you start with this volume, read it, study it, and teach it to others. You will be blessed.
I first read this book in 1999 as recommended resource by my pastor. Here I am in 2013, I still continue to refer to this book. It is just as timely now as it was in 1999. I have been in ministry for 15 years.
