Concise Bible Doctrines is an excellent resource to teach high school age young people about theology. It is deep yet understandable. Dr. Towns has done an admirable job in providing a resource that works very well with both young people and those new to the faith. The setup of this book is such that one could teach one chapter per week for a year. Also each chapter contains a daily Scripture reference pertaining to the subject matter for devotions and/or memorization. I would highly recommend this book.
This is a great introduction to the field of theology. I am teaching a high school class and using this book as the text. It is grounded in the Word of God, deep in its teachings, but easy enough for my students to enjoy reading it. This is a great book for anyone looking to begin a study on biblical, Christian theology!!!
