This book is designed to guide preachers and students of the Word to navigate the complex connection between the old and new testaments. The book specifically emphasizes identifying key truths. The material engages students in discussions, providing them the opportunity to ask questions, find answers and to solidify their Understanding of GOD and His Word. There are many important questions about God and His Word that we need to understand. As Christians, we know all the answers are in THE BIBLE. Nigel started writing this manuscript by answering the tough questions using the Word of God. It took him over ten years to write this material. He used the Catechism method (questions and answers) to make it understandable for everyone to read and comprehend. This material was taught as a course for the past thirty years, and hundreds of students have gone through the course.
