Have one student sit in a chair at the front of the room. Gather 7-10 other students and instruct them to yell simple commands at the other student that is seated in the chair. For example, have one student yell to lift his/her left arm up and another student yelling at the same time to put his/her left arm down. The more commands that are yelled at the same time, the better. Needless to say, the student that is sitting down will get so frustrated that they do not know what to do.
This illustrates that in our daily life, we have so many different influences affecting our lives that it is important that we learn to listen only to Jesus… “the sheep know his voice.”
