Jesus stumped the Pharisees with the following question in Luke 20:41-44:
Then Jesus said to them, “Why is it said that the Messiah is the son of David? David himself declares in the Book of Psalms (110): “‘The Lord said to my Lord: “Sit at my right hand until I make your enemies a footstool for your feet.”’ David calls him ‘Lord.’ How then can he be his son?”
According the Old Testament, Jews were told to honor and be obedient to their parents. Parents would not give their children titles that would clearly elevate their children above them, so this question gave the Pharisees pause. They couldn’t explain why David would refer to his “son” as his “Lord.” As noted in the genealogies reported in Matthew and Luke, Jesus’ genealogies from both His mother Mary’s and His legal father Joseph’s lines included King David. That is why Joseph registered himself in Bethlehem when called to do so just prior to Jesus’ birth. We know from several Old Testament passages that the Savior would come from the line of King David:
“The days are coming,” declares the Lord, “when I will raise up for David a righteous Branch, a King who will reign wisely and do what is just and right in the land.”
For to us a child is born, to us a son is given, and the government will be on his shoulders. And he will be called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace. Of the greatness of his government and peace there will be no end. He will reign on David’s throne and over his kingdom, establishing and upholding it with justice and righteousness from that time on and forever. The zeal of the Lord Almighty will accomplish this.
Jesus fulfilled this prophecy as He fulfilled over 300 prophecies, including Isaiah 53, Psalm 22, Zechariah 12:10 and Daniel 9. He further appeared in the 2nd Temple as prophesied by Malachi (3:1) around 400 years prior. Note the 2nd Temple was destroyed by the Romans in 70 A.D., so we know our Lord had to appear prior to that. All evidence points to Jesus as our Lord and Savior. Jesus is Lord.
Much of this information is attributable to a great conversation I had with a Christian apologist and former pastor named Sam Nesan. He has numerous other interesting insights. Click here to listen: https://www.youtube.com/watch?v=lpLaaOBjV-g&feature=youtu.be.
