This illustration has a double purpose to it. You will need a balloon, filled with helium (so it can rise into the air), and markers. Give each of the youth their own balloon and a marker, and have them write one sin on that balloon. Then have them write on the balloon something to the effect of “Lord, please forgive me/take this sin…” You then have all the youth release their “sins” up towards heaven. Someday when that balloon comes back to earth, whether it be whole or blown up, maybe it might land in someone’s back yard, and that is a way to maybe reach out to someone, or make them curious. I hope you enjoy this idea, and maybe the message will reach someone, and give them new hope.
