The long-forgotten God, revealed to Moses through the most unusual kindling, had just put the world’s biggest military on the bottom of the sea while providing a way for His ragtag people to scurry to safety through two towering walls of water. Who was this God? What is He like? What does He require from the people who are called by His name? Will that people, could that people, ever end up on the bottom of a large body of water? These must have been the questions that were on the Israelites’ minds—these and the giddy gratitude of being free people for the first time in their lives.
