Isaiah foretold a child whose birth would rearrange history: the Son given, the King whose government rests on His shoulder and whose peace will never stop increasing. Christmas celebrates that invasion the moment God entered the world in flesh, the moment the rightful Potentate, King of kings and Lord of lords, took the field. The war is not yet finished, but the outcome is certain: Christ will bring all nations into joyful allegiance. That is why Christmas is a season of victory, of joy to the world, and why every Lord’s Day is, in truth, a weekly Christmas celebrating His coming, His resurrection triumph, and the advance of His Kingdom. God’s design is that all of life become holy, and all days reflect the reign of the Prince of Peace. So lift your head and rejoice: of the increase of His government and peace there shall be no end.
