Book excerpt: Even though the Bible is the perennial best-selling book, many people have a difficult time understanding how to study it. Unlock the Bible in 30 Days is a wonderful tool to gain an overview of the Bible's amazing truths. Colin Smith unlocks the mystery of God's word in three stages: the Old Testament where God introduces Himself, the Gospels where we meet Jesus Christ, and finally the letters of the New Testament where we meet the Holy Spirit. Perfect for either individual or group study.
