Here is a fun object lesson. Fill up a large jar (larger than a quart, if possible) half way up with popcorn. Take a ping pong ball and push it to the bottom of the popcorn. Put the lid on and swirl the jar around. After a few seconds the ping pong ball will rise to the top of the popcorn. After you show this demonstration and let everyone els do it, then discuss what habits and traits a person needs to develop that would help them rise above the temptation and evil in their lives.
