In this introductory class we give an overview of the powerful little book of Jude. Why did Jude write this book? Why did he emphasize so many negative judgments from the Old Testament? How come he refers to the Israelites, Sodom and Gomorrah, Korah, Cain, Balaam, and Enoch? This short introduction gives the key insights into this very relevant book. The PDF course, PowerPoint, and video are also available here.
