Exodus 3:13 “Then Moses said to God, “If I come to the people of Israel and say to them, ‘The God of your fathers has sent me to you,’ and they ask me, ‘What is his name?’ what shall I say to them?” (ESV)
The Israelites had been exposed to more than one god in Egypt. Generations had passed, and some Israelites didn’t know the name of God. Moses asks a legitimate question to God, Which God is going to save them? The god of the sun? The god of the water? The god of nature? God answers Moses with “I AM WHO I AM.” It means the only God that exists, the only God who ever was and the only God who ever will be. The only God that exists is coming to rescue you.
All the miracles that Moses did and all the signs that were performed showed the Israelites, Egyptians and the world around them that there is only ONE God! His name is Jehovah! There is no salvation besides him. There is no other God besides him. Remember this, He is the only one, don’t serve any other gods.
