Moses

We always think of Moses as the Law-giver.  It's true.  The law did come to us from God through Moses.  But what else did Moses do?

He was a savior to the people.
He was a deliverer.
He interceded for them when the Lord said He should wipe 'em out because of their rebellion.

That's not law.
That's mercy.
That's rescue.

And all of that (the law and the rescue) is why Jesus is the prophet greater than Moses (Acts 3:22).
