The Bible teaches that Jesus was the Son of God who became humanity so that He could fulfill the mission of God the Father.
While He was on earth, He was fully God and fully man. He was a teacher who spoke with divine authority and who never sinned. He said that He was “the way, the truth and the life” (John 14:6) and therefore combined the roles of prophet, priest, and king. To say that Jesus was a prophet only will limit who He was during His time on earth.
Jesus did fulfill the role of a prophet. He spoke with authority as God to show people the way to a proper relationship that honors God. He shared the Good News of His love for them so that they could walk in the light of God’s love instead of walking in spiritual darkness. He led people to turn from their disobedience and to follow Him as their Savior and Lord. Jesus taught people how to live a life that obeys and honors God. He focused on matters of the heart and people’s motivation for serving God instead of limiting their behavior to obedience to a set of rules and regulations.
Jesus fulfilled the role of a priest. He spoke with authority the Truth of God to the people. He alone is worthy to enter into the throne room of heaven for He was obedient to the will of God the Father while he was on earth. He was the perfect sacrifice for the sins of humanity. He intercedes on our behalf before God the Father.
Jesus fulfilled the role as king. The kingdom of Jesus was not of this earth. He lived a sinless life, He died and rose again on the third day, and He conquered sin and death. He rules in heaven as King of Kings and Lord of Lords. Jesus taught his disciples that He has all authority in heaven and on earth.
We cannot limit Jesus by saying his was only a prophet, a priest, or a king. He fulfilled all these roles, as only He can, and He is the God the Son.
