Materials needed: Jenga ™ Game (or other game where you stack blocks and it is over when they fall.
Before the game is started you tell the group that while you’re playing this game, be thinking of each tile as being a sin. Then when the game is over and the tiles fall you ask each what did that mean to them. The purpose is to help them realize that by stacking one sin on top of another, then another, and so on, eventually you will crumble. But by going to our Savior and asking for forgiveness, we have no sins to stack. My Sunday School class loved it and I was so surprised at how much sense it made to them.
