O Rex Gentium or O King of the Nations is title for the day. During a time in which we are still at war, all of us long for peace. But there can be no peace without the Lordship of Jesus.
As we reflect on this title, I like what C.S. Lewis wrote in Mere Christianity:
Christianity is the story of how the rightful King has landed, you might say in disguise, and is calling us all to take part in His great campaign of sabotage.
The reign of the King must first reign in our hearts if His Kingdom is to advance. In these last days of Advent, it is a perfect time to repent, turn to the Gospel and unite ourselves closer to the King. As we wait for our marching orders to spread His Gospel of peace may we pray:
O King of all the nations, the only joy of every human heart; O Keystone of the mighty arch of man, come and save the creature you fashioned from the dust.” Isaiah had prophesied, “For a child is born to us, a son is given us; upon his shoulder dominion rests. They name him Wonder-Counselor, God-Hero, Father-Forever, Prince of Peace.” (9:5), and “He shall judge between the nations, and impose terms on many peoples. They shall beat their swords into plowshares and their spears into pruning hooks; one nation shall not raise the sword against another, nor shall they train for war again.” (2:4) .
