Gather the following items:
• a rock that has a flat surface (or a hollow block or any heavy item)
• some sand (or loose soil or any substance that will separate when wet)
• any solid item that will represent a house or a building
• a big pitcher of water
• two trays
Today, we are going to learn about foundations! A foundation is found at the base of a house or a building. It is the lowest point that should be strong enough to be able to support the weight of the entire building. Different kinds of buildings require different kinds of foundations. A two-story building will need a smaller foundation, while a thirty-story building will need a much stronger and more stable foundation.
Let’s see what happens when you build on a foundation that is not strong enough for your building. Put the rock on one tray and the sand on the other. Now, place the object that represents the house on top of the rock and pour water from the pitcher. Water represents strong rains, storms, and floods. The house will stand because the rock is solid. Now, place the house on top of the sand and similarly, pour water on the sand. The sand will crumble and not be able to support the house. This is because the sand is not strong enough to support a house and it is not a good foundation for a house.
Can you imagine a thirty-story building that has sand as its foundation? What do you think would happen? (Let the children give their answers.)
Just as a house or a building needs a good solid foundation, our lives must have strong foundations, too.
Throughout the week, we have been studying how God’s word can bring life to us and how it can change and renew us. The key is to build our lives on the truth of God’s word and do what it teaches. Let’s read what Jesus taught the people in Matthew 7:24–27.
