My Bible study has used the LIFECHANGE series through many books of the Bible. The studies are thorough and the questions are thought provoking. The personal application questions are also useful. Rare to occasionally there are questions that are somewhat ambiguous. Unfortunately there is no answer book. We look forward to the study of the gospel of Luke after the first of the year. I highly recommend this series for your small group Bible study. Our study have ordered from CBD each time we start a new series. The personnel are efficient and courteous and delivery is on time.
