You need to “think small” in order to appreciate the impact of Exodus on its original audience. God didn’t just thunder a theological pronouncement from the sky in order to reveal himself to the world. He proved himself by duking it out with the mightiest deities they knew. More than once, when Israel approached other nations, the nations reacted in terror at the reputation of this God who had vanquished the Egyptian gods (see Num. 22; Josh. 6).
