This book is intended not only to win souls, but also to give new converts systematic understanding of what it takes to grow and be productive believers. This is a Spirit-guided, easy-to-follow Bible course on salvation and growing in faith. This work accentuates the significance of the word of the Ethiopian Eunuch, who, when the Apostle Philip asked him the question in Acts 8, "Do you understand what you are reading?" he responded by saying, "How can I understand except someone guides me?" May this book serve as a guide to the Christian in the journey of faith, and a useful tool to the soul-winner.
