Jesus told Pilate that His kingdom was not of this world and Pilate didn’t get it. He asked Jesus if this meant that He was a king. Jesus answered:
“You say that I am a king. For this purpose I was born and for this purpose I have come into the world—to bear witness to the truth. Everyone who is of the truth listens to my voice.” (John 18:37, ESV)
Pilate’s famous question, “What is truth?” proved that he wasn’t listening. But for those who do have ears to hear, let us consider why Jesus said He was born. He left His Father in heaven and took on flesh in Bethlehem in order “to bear witness to the truth.” What truth? If Pilate had asked “What truth?” instead of “What is truth?” he would have been in a much better position.
The answer is, Jesus was born to bear witness to all truth. That’s a lot, but at least we can say that it includes the truth of His identity. Jesus is the Savior King. We know it from the earliest chapters in the Christmas story. Gabriel told Mary,
you will conceive in your womb and bear a son, and you shall call his name Jesus. He will be great and will be called the Son of the Most High. And the Lord God will give to him the throne of his father David, and he will reign over the house of Jacob forever, and of his kingdom there will be no end.” (Luke 1:31–33, ESV)
Gabriel told Joseph that Mary would “bear a son, and you shall call his name Jesus, for he will save his people from their sins” (Matthew 1:21). The angel announced to the shepherds, “Unto us is born this day in the city of David a Savior, who is Christ the Lord” (Luke 2:11). When the wise men arrived sometime later, they asked, “Where is he who has been born king of the Jews?” (Matthew 2:2)
Jesus was born to bear witness to the truth, the truth of who He is and the truth of what we need. When we come to the Lord’s table in faith, we also bear witness to the truth that we were born in sin needing a Savior, born as enemies rebelling against the King, and that we trust His death to bring us life.
