One of the first church tours I ever went to was at Granger Community Church in Granger, IN. Their creativity and innovation was like nothing I had ever seen before. (well, other than Disney) Every kids room was designed in a different theme. They even had slides that took you from the kids check in area, right into the class room. When kids landed in the room, they could look at the monitor and wave good-bye to their parents. The parents could wave back using cameras and monitors at both ends of the slides.
What I love about themed spaces is it communicates to kids… “we think you are pretty important and we hope you have fun here”. If kids want to come to church they will beg their parents to bring them. That means more opportunities to tell them about Jesus and build relationships with them.
