Charles Ryrie is a biblical sound author and anything he writes is great. This book on Basic Theology would be good for anyone desiring to grow in their faith as it deals with basic issues Christians should know about. To know these things will help one from following false doctrine. It is great for any one's book shelf.
For those who are ready go in-depth, to begin to study God's Word with a scholarly approach, this is a perfect book.
Most importantly, it reveres the Word of God - it does not lightly brush aside pages of the Bible as symbolic or as untrustworthy "because we know better now". Instead, it is faithful to every word of the Bible.
