For more than thirty years, John Piper pastored in the rough-and-tumble realities of downtown Minneapolis, preaching his people through the ups and down of life one Sunday at a time. When it came to capturing a generation of joy in one final sermon series, he turned to ten trademark truths to leave ringing in his people’s ears. These ten are world-shaking truths—each astonishing in its own way. These surprising doctrines, as Piper writes, are “wildly untamable, explosively uncontainable, and electrically future-creating.” Join a veteran author, pastor, and Christian leader as he captures the ten astonishing, compassionate, life-giving, joy-awakening, hope-sustaining truths that have held everything together for him.
