Why should people follow the Bible references in Les's class instead of just listening to him?
Students should follow along in their own Bibles because Scripture itself is what counts, not the teacher's words. The class maintains that no human speaker can make the difference; the goal is to understand what God's Word says. So listeners are urged to find a Bible and verify the references themselves.
Les explains that the class is just an informal Bible class. He tells viewers and students to find a Bible and sit down and follow these references with us, because he always maintains it's the Word of God that counts, and nothing he or anyone else can say can make the difference. His stated aim is to help people understand what God's Word says. Therefore, following the Bible references is what matters, not merely listening to him.
