Description
This object lesson illustrates how Satan tries to fill our minds with worries, fears, doubts and many other things so that there is no room for God’s truth, peace and joy.

Audience
Children, youth and adults

Materials
•    Tennis balls (9-12)
•    Permanent marker
•    Posterboard (1 sheet should do)
•    Scissors or some other cutting device
•    Block pattern (You can find this in the file “Catch – Block Pattern.ppt” located on the Lesson and Material Downloads page at http://www.teachthem.wordpress.com.)
•    Clear tape

Preparation
•    Write a different label on each of the tennis balls.  They should read: Worry, Fear, Jealousy, Anger, Doubt, Entertainment, Video Games, Depression, Obsessions, Fatigue, Hatred, Self, Regret, Embarrassment, Cute Boy, Cute Girl (or whatever you think appropriate – they should be things that Satan might use to fill up our minds so that we don’t have room to think about things God wants us to think about)
•    Make several blocks out of posterboard using the block pattern mentioned above and the clear tape
•    Label the blocks: Truth, Love, Joy, Peace, Wisdom, Vision, Faith, Patience, Kindness, Goodness, Faithfulness, Gentleness, Self-Control, Righteousness, Hope (or whatever you think appropriate – they should be things that God wants to fill our mind with).  You could also focus on Philippians 4:8 and do blocks that say “True, Noble, Right, Pure, Lovely, Admirable.”  You will need 9-12 blocks.
•    Practice the script.

Procedure
Use the following script (or modify to suit your needs):
o    “I want to show you an illustration of the battle for your mind.”
o    “Satan and God are in a war.  It’s evil against Good.”
o    “Your mind and heart are the battlefields on which this war is waged.”
o    “Satan knows that he can’t do anything to damage God, so He tries to hurt the Creator through his creation, and that’s us.”
o    “Satan first wants to hold as many of us prisoner as possible, so that we never get to join God’s army.”
o    “But even after we become Christians and join God’s side, Satan doesn’t give up.”
o    “If he can’t have us on his side, he will at least try to make us ineffective by pulling our minds and hearts away from God.”
o    “Satan knows that if he can win the battle for our mind, we will be ineffective for God.”
o    “So the tactic we are going to talk about is how Satan tries to fill our mind with lots of things so that there is no room for what God wants to put in there.”  (Ask for a volunteer to come forward.)
o    “Let’s pretend that this person represents our minds.”
o    “And let’s pretend that these tennis balls each represent something that Satan want to fill our mind with so that we don’t think about Godly things.”  (Read on of the balls out loud, and show it to the group.  Then hand it to your volunteer.)
o    “If that one doesn’t completely occupy our minds, Satan will give us more things to think about.  (Read several more balls, and hand them to the volunteer.)
o    “He will keep this up, filling our minds with all kinds of junk until they are completely full.”  (Read off the rest of the balls, and hand them to the volunteer, who should be having trouble holding them all.  If he/she drops any, pick them up, and hand them back to the volunteer.)
o    “When our minds are full like this, there is not room for what God wants to put in.”  (Pick up one of the blocks, and read it off.  Try to fit it into the volunteer’s hands, but give up in frustration.)
o    “But who ever said that we have to hold anything that Satan gives to us?”  (Instruct volunteer to drop all the balls and to take the block.)
o    “Now, without all the junk that Satan tries to fill our minds with, there is plenty of room for what God wants to fill our mind with.”  (Read off each of the blocks, and then stack them neatly in the volunteer’s hands.  Keep one for the next part of the lesson.)
o    “Notice how much easier it is to hold the things that God gives us rather than the things Satan tries to fill our minds with.”  (Pick up a few of the balls off the floor, and toss them at the volunteer while saying, “Catch!”  Hopefully, the volunteer will drop everything to catch the balls.  If he/she does, then ask, “Why did you drop all God’s good things to catch what Satan threw you?”  If the volunteer doesn’t fall for the trick, keep tossing balls in his/her direction.  Then say, “It was good that you didn’t fall for Satan’s trick.  He won’t give up.  He will keep tossing bad thoughts at you, and you have to be careful to not accept them.”
o    “If Satan does succeed in getting in one of his thought bombs, the Bible tells us clearly what to do about it.”  (Have volunteer read 2 Corinthians 10:3-5.)
o    “The war we fight is different than most wars.  It’s a thought war.”
o    “When one of Satan’s thought bombs gets in, we are to take it captive to Christ.”  (Have volunteer take one of the thought bombs and hold it up like he/she is giving it to God.)
o    “God will then take that thought bomb and replace it with one of His truths.” (Exchange the ball for a block.)
o    “This war is difficult, and it’s long.  You have to keep fighting all your life to keep your thoughts pure and true.” (Have volunteer read Romans 12:2.)
o    “God wants us to be transformed by the renewing of our minds.  That means taking evil and ungodly thoughts captive every time we have them and exchanging them for truth and wisdom with God.”
o    “You see, when God saved us, he gave us a completely new heart, but we have the same mind that we had before we were saved.”
o    “In order to get a new mind, we have to exchange the bad thoughts one by one for good thoughts.”
o    “Maybe a good way to think about it is this: our hearts after trusting Christ are like moving into a brand new house, but our minds after trusting Christ are like moving into an old house that needs a lot of renovation work.”
o    “The good news is that God will help us with all the renovation.  He will be our general contractor, who guides us in all the work.”  (Thank volunteer, and let him/her have a seat.)
