I never stopped to think about that...

Matthew 22:41-45 Now while the Pharisees were gathered together, Jesus asked them a question, saying, “What do you think about the Christ? Whose son is he?” They said to him, “The son of David.” He said to them, “How is it then that David, in the Spirit, calls him Lord, saying, “‘The Lord said to my Lord,“Sit at my right hand,until I put your enemies under your feet”’? If then David calls him Lord, how is he his son?” The religious leaders of Jesus' day had long pondered over the Messiah: Who was He? What would He be like? How would we know Him? They had many prophesies and psalms they viewed as describing the Messiah, from which they sought to form a concept of Whom to expect. That the Messiah would be from the line of David was clear from several sources. But they never stopped to consider the question Jesus poses here, posed by the Messianic Psalm He quotes: How can David's Son be David's Lord? For that to be true, He must have existed before David, yet be born after; He must be both the Son of David and the Son of God. Such revelation is overwhelming to be sure.
