The first step to repentance and faith is to know the God who made us.
So the first words God speaks from Sinai are, “I am Yahweh, your God.” We are obligated to keep His commands because He IS. Yahweh is the only existing thing that exists on its own. And He made us, so He is our God. All creation owes God worship and praise, for being made by Him. We must keep God’s ways finally because He redeemed us. Like Israel freed from Egypt, God set us free from the tyranny of the devil and our overpowering sin.
