Talk about how you respond to authority in general, and how that compares to how you respond (positively or negatively) to the idea of obeying God. How is your obedience linked to trust? Why do you think God asks us to obey Him? Identify 2-3 things that God is saying to you (or has already said to all Christians -- i.e. principles derived from studying your Bible). Which ones have been hardest for you to apply in your life? Discuss what you're doing about these commandments, looking for tangible/objective steps of obedience. Follow-up over the next several weeks with encouragement to your friend.
