A great Bible Study for Boys!
Boys have great energy, so how can we funnel that energy and interest into digging into the Word and conforming to His image?
Use the first 3 movies from Star Wars (episodes 1,2 & 3), in paralleling Anakin Skywalker's steady downfall into negative fruits alongside of Galatians 5:19-25.
Get your dictionary handy as well, as you read through those nasty fruits in Galatians, you'll be mining through each one with that dictionary to really get the kids to understand what each one really means. Then, talk about the movie(s) and encourage the kids to pick out scenes that show that bad fruit in action so that they can begin to grasp by an example (in Anakin).
Not only does this study grasp their interest, but it encourages them to discern and teaches them to investigate based on the Word of God.
