The students will be able to explain that David trusted in God because he had proven God to be his strength, and will be able to relate how this was proved in his encounter with Goliath. They will be able to tell what promise is given to those who trust God. (They will be kept in perfect peace.)
Introduction: Draw a face with large, scared eyes at the top of your chalkboard. Ask your class to tell some of the things they are afraid of, or things they know others fear. Write these down. Then explain that the things we are afraid of can be like a giant to us, but God promises to help us win the victory, even over giants!
Climax: God helped David slay the giant.
Conclusion: David was able to win the victory because he trusted in the living God and not in his own ability. We can also have victory if we will trust God to help us.
Response: The students will be able to tell the story of how David slew the giant, and will be able to relate this to how we can also trust God when we face problems or troublesome situations.
The familiar story of David and Goliath is still inspiring to all who study it. It must have been an amazing sight to see a stripling like David face the massive giant some nine feet tall. Saul's armor was of no use to David, for he chose to rely on the weapons he had proven, his sling and his God. There was also a spiritual side to this battle. Saul and his army were cowering before this man who defied God, apparently because they had forgotten God's promises and commands to never fear their enemies but to trust in the Lord (see Exodus 14:13-14; Numbers 14:9; Joshua 10:8). David recognized the problem immediately and said, "Who is this uncircumcised Philistine that he should defy the armies of the living God?" and a little later, "Let no man's heart fail because of him; thy servant will go and fight with this Philistine" (1 Samuel 17:26,32). David's confidence was not in his own prowess but in the power of God (1 Samuel 17:37). Through God's direction only one stone was needed to put the whole Philistine army to flight. A man skilled in the use of a sling could hurl a baseball-sized stone with great accuracy at the speed of 100 miles per hour.
Having rejected Saul's armor, David went out to meet the enemy with the equipment of a shepherd: a staff, a shepherd's bag, and a sling (1 Samuel 17:40). And this was appropriate, seeing that he was the newly-appointed shepherd of the people going out to defend the threatened flock of God. He was willing to jeopardize his own life for the sake of the sheep, proving again that he was "a man after God's own heart."
Special Instructions for Unit 26: Prepare the "David and Goliath" place mat for your students.
Use people to act out the story of David and Goliath. To show the contrast in size, use the tallest man you can find in your church and one of the children in the Sunday school department. Tell the children that with God on our side even the smallest person can win the battle with a giant.
Set up a puppet show for the children, using whatever puppets you need, to tell the story of David and Goliath.
There are some excellent tape/record and book combinations telling the story of David and Goliath. Consider doing an overhead review using the book as the basis for your illustration, and the tape as the background narration.
