Did God really want to kill Moses? 4:24 tells us He really did. Why? Wasn’t Moses going back to Egypt because God told him to? Hadn’t God said Moses would deliver the Israelites out of bondage? It seems odd that God would decide to kill this man.
If you read 4:21-26 you read the Gospel. Yes, Moses was going through the motions of obedience, but the fact remained he hadn’t been circumcised. That was disobedience. That was sin. And sin comes with a death penalty, no matter who you are, no matter how much you might appear to others to be following God.
It wasn’t until Moses was circumcised, until blood had been spilt, that God let him go. The same requirement is in effect today. Without the shedding of blood there is no forgiveness of sin. (Hebrews 9:22)
After Jesus, His is the blood that brings salvation. No one needs to be circumcised or cut or killed in order for sins to be forgiven. But make no mistake, blood needs to be applied in order for God to pardon a death sentence.
And that’s the Gospel.
Our bodies don’t need to be circumcised, but our hearts do. That involves a true repentance, an acceptance of God’s will. Forgiveness doesn’t happen until the blood of Jesus is applied to a surrendered heart. Then, and only then, will God “let (us) go” as He did Moses here in Exodus 4.
You can do all the religious stuff, and go through the motions of obedience like Moses did. But even Moses had to address his sin.
And so do you and I.
