How do we know Jesus is the King and Priest according to the Bible?

The sermon emphasizes that Jesus is depicted as both a king and a priest, a unique combination never seen in Old Testament times where these roles were separate. In Zechariah 6:12-13, it is prophesied that Jesus will sit and rule on His throne while also serving as a priest, indicating His dual authority and mediation. His kingship assures us of His sovereignty over all creation, while His priesthood means He is the mediator between God and man, offering peace through His sacrifice. This dual role is central to understanding Christ’s identity and the Gospel.
