David's route to the throne has been through suffering. In this respect, he reminds us very much of a greater King to come, who was also born in Bethlehem, had a group of followers, and had to defeat evil through suffering. Like with David, people recognized that the Lord Jesus Christ had the Spirit of God very much upon Him and saw that He too was replacing a decaying and apostate leadership with something better.
Nathan's prophecy, which we read of in this chapter, speaks with great clarity about David's line, something which David also foresaw clearly as we learn from Psalms 16, 22, and 110. David foresees a Son of his, whom he would be calling 'Lord'. This is great David's greater Son, our Lord Jesus Christ. He is going to surpass David in glory, power, authority, honour, obedience, longevity, and scope.
