I have studied the Bible and knew a lot of the principles but could never find very many verses when I needed them or someone else needed them. Mr. Morgan's approach to learning the verses, his thoughts - which are about 1 1/2 pages per verse - are perfect to use as a devotional or just helpful to memorize that scripture. It has been invaluable to me and I bought 5 more to give away. My husband and son and neighbor are working through them now and I see God's Word which is "living and active" (Hebrews 4:12!) having an impact on our lives.
