Perhaps no other ministry active today has done more than Ligonier Ministries to take Christian theology and package it in a format that is easily accessible to the average layperson. R. C. Sproul has written many wonderful works detailing various aspects of Christian doctrine and practice, with such classics as The Holiness of God, Chosen by God, Knowing Scripture, and more recently, Everyones a Theologian.
This work is an excellent supplement to these works. Drawing from years of answering questions via radio and other formats, Sproul answers many of the most common queries that Christians and non-Christians alike may have regarding the faith. Although it is neither a work of systematic theology nor of apologetics, it manages to combine elements of both, as well as cover such practical issues as marriage and family life, as well as Christian involvement in politics. This book does this in a conversational format that really makes it feel like the author is speaking directly to the readers concerns.
Now Thats a Good Question! is the kind of tome most laypeople and pastors should have on hand in other to get a quick answer to common questions regarding the faith. At the same time, I would recommend Sprouls other works as well, as they provide more in-depth answers to many of the questions posed within this book but are answered only in a few pages.
I bought this book because I was getting the e-devotional and found I wanted to know more. It has not disappointed. In fact I also bought another Sproul book, Essential Truths of the Christian Faith, and would also recommend it highly. Sproul writes in an insightful manner and I find him very thought provoking.
