What is the royal line of David's house leading up to in 2 Samuel 7?
According to 2 Samuel 7, the royal line of David's house leads up to the coming of the King, the Christ, the Messiah. It would come through Solomon on one side and Nathan on the other, with God speaking primarily of Solomon in verse 14.
Les explains that 2 Samuel 7 contains the Davidic covenant, a covenant God made with David concerning his offspring, the nation of Israel. The royal line of David's house would lead up to the coming of the King, the Christ, the Messiah. It would come down through Solomon on one side and Nathan on the other. Although verse 14 primarily addresses Solomon—"I will be his father, he shall be my son"—God is looking at the long view of the whole nation of Israel, whom He would chasten with the rod of men and the stripes of the children of men. Verse 15 begins with "But," showing the flip side: He will chasten them when they come into unbelief and abject behavior.
