'Our Father, who art in heaven.' The opening words of the Lord's Prayer have become so familiar that we often speak them without a thought, sometimes without any awareness that we are speaking at all. But to the disciples who first heard these words from Jesus, the prayer was a thunderbolt, a radical new way to pray that changed them and the course of history. Far from a safe series of comforting words, the Lord's Prayer makes extraordinary claims, topples every earthly power, and announces God's reign over all things in heaven and on earth. In this groundbreaking new book, R. Albert Mohler Jr. recaptures the urgency and transformational nature of the prayer, revealing once again its remarkable, world-upending power. Step by step, phrase by phrase, The Prayer that Turns the World Upside Down explains what these words mean and how we are to pray them. The Lord's Prayer is the most powerful prayer in the Bible, taught by Jesus to those closest to him. We desperately need to relearn its power and practice. The Prayer that Turns the World Upside Down shows us how.
