God loves to "magnify His sovereign strength." This is the answer to the question John Piper poses in the poem "Mighty Mercy": Why did God choose such "strange and roundabout" providence "[t]o get Messiah where He must be born?" This poem exalts God's absolute sovereignty in the "flukes of history."
Why did He choose a northern maid From Nazareth, who had to trade Her Galilee for Judah just To get Messiah where He must Be born? A strange and roundabout Procedure for a God, no doubt, Who values His efficiency And rules the world from sea to sea! Why not a girl from Bethlehem? Well half the girls in town would stem From David's line. And carpenters Aplenty there could bear the slurs And gossip on a virgin got with child, who blushed and said she'd not Once kissed her man this whole year past. Why not? Because God's power is vast, And in one little virgin birth His sovereign joy and mighty mirth In saving us from evil bent Could never, never rest content. Instead He turned and set His sight To spangle Rome with all His might; And took a girl from Galilee To magnify His sovereignty. And made the Roman king conspire With God, to serve a purpose higher Than he or any in the realm Could see—a stroke to overwhelm A few with faith and cause their heart To know the truth, at least in part, That, though God loves efficiency And rules the world from sea to sea, He does not go from here to there By shortest routes to save His fare. He'd rather start in Galilee, Then pass a law in Rome, you see, To get the child down south at length, And magnify His sovereign strength. God rules the flukes of history To see that Micah's prophecy Comes true. Why did He choose a maid From Nazareth? Perhaps she prayed That endless mercy might abound And take the longer way around. The mighty mercy we adore As we light advent candle four.
