15 “The Lord your God will raise up for you a prophet like me from among you, from your brothers—it is to him you shall listen— 16 just as you desired of the Lord your God at Horeb on the day of the assembly, when you said, ‘Let me not hear again the voice of the Lord my God or see this great fire any more, lest I die.’ 17 And the Lord said to me, ‘They are right in what they have spoken. 18 I will raise up for them a prophet like you from among their brothers. And I will put my words in his mouth, and he shall speak to them all that I command him.
In the long arc of history, the prophets of God foretell of one even mightier than they are. Here, Moses tells the Israelites that one day a new prophet will come and the people shall listen. At Horeb, the people saw the great fire of God and heard his voice and trembled. They needed a prophet and priests to intercede on their behalf. They needed a connection to the divine.
Peter, when preaching in Acts 3, cites this passage and says it is about the Messiah.
Picture the image. The people, confronted by God, tremble and believe they will surely die. They need an intermediary to stand between them and God. What they got was a baby, lying in a manger. The people could look on the face of God as a baby and not fear and not tremble.
Christ Jesus is approachable. He intercedes for us and one day we shall all listen to him, even those who do not believe. By then, it will be too late to listen willingly. For now, be still and know that Christ Jesus is God.
