As the Israelites make their way out of Egypt, Pharaoh has a change of heart and chases after them. As they get to the Red Sea, God parts the Sea, to allow the Israelites to cross on dry ground. As the Egyptians close in on them, the walls of water on the Red Sea collapse on them once all the Israelites are safe. When Jesus comes along, He doesn't part the sea, rather He walks upon it, showing His power over water, just like He did in the Exodus. God still works miracles with water today, and all we have to do is look at the baptismal font.
