“And when thy days be fulfilled, and thou shalt sleep with thy fathers, I will set up thy seed after thee, which shall proceed out of thy bowels, and I will establish his kingdom. He shall build an house for my name, and I will stablish the throne of his kingdom for ever.”
2 Samuel 7:12–13
When Louis XIV, known as the Sun King, was just five years old he was crowned the king of France. For the next seventy-two years, though he did not exercise power on his own until he came of age, he was the ruler of the people. For decades, no one in France knew any other ruler. It must have seemed to some like Louis XIV would reign forever. But like all men, he did eventually die and the crown passed to his son.
Jesus is the literal fulfillment of the promise God made to David that one of his descendants would rule forever. Many of David’s descendants ruled in Jerusalem, some poorly and some well. But none of them had a lasting reign. Eventually the kingdom itself was destroyed, but God’s promise remained. He does not work on our time frame or according to our understanding, but He always does exactly what He says He will do.
Jesus will never grow old or feeble and need to be replaced. He will never be overthrown in a revolution. He is the king forever, and we know how the story ends. “And the seventh angel sounded; and there were great voices in heaven, saying, The kingdoms of this world are become the kingdoms of our Lord, and of his Christ; and he shall reign for ever and ever” (Revelation 11:15).
