At the start of the lesson I had each person write on their popsicle stick something that they enjoyed spending their time on. (hobbie, sports, etc.) We talked about the importance of spiritual things and how the world tends to pull our focus away from those things. Have them look at the picture that your brought. (do this from a distance of atleast 7-10 feet) Know ask them to hold up their popsicle stick and put it in their field of vision. While focusing on Christ you can still keep in line other things. What would happen if you changed all your focus off of Christ and only on your stick. As you do this you will notice that your spiritual focus has been thrown off because you are focusing to much time on the other.
