Book excerpt: Dr. S. Franklin Logsdon, Bible teacher and evangelist, says of this book: "These principles of Bible study by Dr. J. Edwin Hartill have been tested and proved in his own personal teaching for many years. They are succinct, pointed, practical, original, understandable -- simple keys to unlock the storehouse of Scripture to things both old and new. This publication makes a distinct contribution to Bible lovers in their search for increased knowledge of divine truth. It is a privilege and an honor to commend it to God's people." Using a graphic combination of text, charts, and outlines, Dr. Hartill states, "I trust that as you study these principles, your understanding of the Word and your love for its truth may deepen, so that you may more ably pass it on to others."
