Who was the King of kings that came from David's royal bloodline, and through whom was he born?
According to the promise in 2 Samuel chapter 7, the King of kings from David’s royal bloodline is Christ, the Lord of lords. He was born through Mary, with Joseph as His legal father; both Mary and Joseph came down the royal family bloodlines of David and Solomon.
Les teaches from 2 Samuel chapter 7 that David was promised a royal house or royal family of kings coming from his loins to rule and reign over Israel, and that through that line of kings would one day come the King of kings. That was Christ, born of Mary, with Joseph as His legal father, both descending from the royal family bloodlines of David and Solomon. Les explains that God's promise in verses 14–16 assured David that his house, kingdom, and throne would be established forever; God cannot lie. The royal family would continue beyond history into eternity, and out of David's royal family would come the King of kings, the Lord of lords, who will come back to the nation of Israel.
