You will need two large magnets for this object lesson. Discuss James 4:6 which reads, "God resisteth the proud, but giveth grace unto the humble." Explain that the word "resisteth" means "to push away." Try to place the magnets together by pushing the sides with the same polarity together. The magnets will jump away from each other. If time permits, allow each of the students to try to place the magnets together in the same way. Explain that God's relationship to the proud is the same as the relationship between the two magnets and that people with a heart full of pride cannot get close to God.
You will need a house built of construction paper, a metal cake pan, and a match or lighter. Take time to describe the house to all the children, pointing out different rooms. Explain that their lives are like a house. Read Proverbs 16:18 from the Bible. Define "destruction" in terms they can understand. Illustrate by placing the house inside the cake pan and then setting in on fire. Allow it to burn until there is nothing left but ashes. (Have a glass of water nearby in case of emergency.) End the lesson by reminding the students that similar destruction can take place in their lives if they allow pride to take root.
You will need one large brown balloon and two smaller green balloons. Blow the brown balloon up to its full size and tie it. Blow one of the green balloons just enough to make a small ball and the other one larger than the first green balloon, but much smaller than the brown. (You may want to tie the larger green balloon with a ribbon instead of tying it in a knot since you will be adding air to it during the activity.) Read or tell Aesop's fable, "The Frog and the Ox." As the father frog boasts of being able to blow himself up to the size of the ox, add air to the larger green balloon. Continue to add air until the balloon pops. Explain the fable to the children to make sure they understand the consequences of pride.
You will need a bag filled with various weeds. Lead the children in a discussion on weeds, displaying the contents of your bag. Explain how weeds are harmful to useful plants and that if left to thrive, they will actually choke and kill the grass, flowers and other more pleasant growth. At the end of the discussion, remind the children that pride is just like a weed. It has no good purpose and if left unattended, it will choke and destroy the good parts of their lives.
