How did Christ act as Prophet?

Mala Chindongo explains in this video that when we think of Christ as a prophet, we should think about teaching ministry. 

Christ came to teach us about God, the way of salvation, and how we should live. Christ taught, warned, rebuked, encouraged, and comforted those around Him. He declared that sinners needed to repent and be saved.

Mark 1:14-15 (NKJV) – “Now after John was put in prison, Jesus came to Galilee, preaching the gospel of the kingdom of God, and saying, ‘The time is fulfilled, and the kingdom of God is at hand. Repent, and believe in the gospel.’”
