It was 1927 when Donald Grey Barnhouse, then pastor of Tenth Presbyterian Church in Philadelphia, began refining the Bible study lessons that eventually grew into this book. With over 200,000 copies sold in a dozen languages, Teaching the Word of Truth continues to present sound and time-tested Christian educational material for a new generation. Teaching the Word of Truth contains four courses, each consisting of twenty lessons, with in-depth hints for teachers and suggestions for adapting the material for children.
