From the Preface: I feel challenged knowing that people like you have acquired this book. The task of educating young people is not easy and we should be very careful when we search for material to do so. It will help you to know that this material is based on biblical teachings and has been prepared by an international team of people trained in different disciplines, but with the common denominator of knowing and loving the young people in their churches. The 52 lessons have been divided into seven thematic units. Not all units have the same number of lessons, as they vary according to the topics covered. Considering the characteristics and needs of the stages of youth, this book is designed for two age groups: 12 to 17 years and 18 to 23 years. You have the freedom to adapt it according to the needs of your Sunday school class or Bible study group in your local church. - Patricia Picavea, editor
