Why is the concept of Jesus as a Prophet important for Christians?

In Deuteronomy 18:18-19, Moses speaks of a Prophet who will arise, which is fulfilled in Jesus. This title is significant as it emphasizes that Jesus is not just a deliverer of words but the living Word Himself. He spoke with authority unlike the scribes and Pharisees, establishing a new covenant through His teachings. For Christians, His role as the Prophet underscores the necessity to heed His words for spiritual life and direction, as they are directly from God and reveal His nature and will.
