This game will require about 20 water balloons, it’s just a safe amount. You will need to fill these balloons up before your meeting.
What you do is you get together with your group to talk about how Jesus died for our sins and that He was the sacrifice for all our sins.
Then, have volunteers form two teams that will have some form of race. Any type of race will do. This worked great with a relay race. Now, the team that wins will have to talk amongst themselves to choose someone to sacrifice. The person that they choose gets to be hit by a water balloon by his/her teammates.
Not everyone wants to get wet, so the person the team chooses takes the balloon instead of everyone else.
This worked great for outdoor VBS games.
