Matthew 1:6–12 shows God’s faithfulness to His promise to David, even when human kings failed. David longed to build a temple, but God promised him an eternal dynasty—a promise that seemed fulfilled in Solomon until his heart turned away. Rehoboam’s harshness split the kingdom, and later kings wavered between worshiping God and idols, leading to exile under Nebuchadnezzar. Yet God’s plan endured: Jesus, the true Son of David, came as Messiah and will reign forever in a new heaven and earth. This reminds us that God is faithful despite human failure, works through imperfect people, and accomplishes His will even in our darkest days.
