35.99 As a pastor and author, John Piper has long been known for singing the song of God’s glory with uncommon passion. His newest book, the massive Providence—written more than three decades after his signature volume Desiring God—confirms that Piper has even more Scripture-soaked verses to belt out. At this stage of his ministry, it might be helpful to imagine Piper playing the role of C. S. Lewis’s character Digory Kirke from The Chronicles of Narnia. Piper, though, is Kirke at the age of his greatest influence, when he has grown from the boy Digory to the aged professor who welcomes the Pevensie children to stay at his estate to find in his wardrobe a portal to a new world.
