Body of Christ Game Station
Here is an idea for a game station about the body of Christ. The emphasis of the lesson would be that we are all important to the body of Christ and all have a role to play in the life of our church.
Start with a game set like Jenga. Have different spiritual gifts, volunteer positions, acts of service you can perform at church written on each piece. There might be blank pieces where students could offer up their own suggestions, or even names of people. A nice structure is built. Then the students start pulling pieces out and reading what is on the piece. That gift/role/whatever is no longer a part of their church/body of Christ in this game. What eventually happens? There are alot of spiritual gifts laying around not being used for the church (and its ministries). The structure may even collapse and no longer serve its purpose.
You could take it a step further and talk about the church's foundation. Is it the firm foundation of Jesus Christ our Lord (as the hymn says)or is it built on the shaky foundation of personal opinions, "values-free" thinking, emotions, etc. You could try building your Jenga structure on a hard tabletop or in a box filled with packing peanuts.
