Our story was from the book of Joshua, and we got to tell your child about the Israelites crossing the Jordan River. What a huge miracle! God stopped the flow of the water so the Israelites could walk right through it on dry ground! Joshua wanted the Israelites to remember for a long time what God did for them, so they carried 12 rocks from the river and piled them together. Whenever they saw these rocks, it was to remind them of what God did. A way to further this lesson with your child would be to think of things that God has done for your family and thank God together.
