The document discusses four times in history where God displayed his mighty works: 1. God freed the Israelites from Egyptian slavery through the ten plagues and the death of Pharaoh's son. 2. God guided the Israelites when they felt confused seeing the vast Red Sea, after having left Egypt. 3. God led the Israelites to victory despite many battles with enemies, allowing them to keep their promised land. 4. God provided for the Israelites' basic needs even during times of scarcity.
