We highly recommend these studies from Northpoint Church. They are set up in a way that you can give them to everyone in your group ahead of time. This way they can look at the text, questions, as well as study notes to prepare for your weekly discussion if they would like to. It also gives them a passage of Scripture for their own devotional time.
In addition, the studies are crafted in a way that really encourage your group members to share about their life and how the passage is inviting them to live differently.
