“Luther’s breakthrough had a dazzling, corrosive simplicity to it. The power of those twin principles, “faith alone” and “Scripture alone,” lay in the word “alone.” There is nothing and no one else other than God incarnate in Jesus Christ worth attending to. Being a Christian means throwing yourself abjectly, unreservedly, on Christ’s mercy. Living a Christian life means living Christ’s life—that is, abandoning all security and worldly ambitions to follow him “through penalties, deaths and hell.” It is only then that we may find peace. That ravishing paradox is at the heart of Protestantism. It is a further paradox that such a profoundly personal insight should have such an impact on the outside world.”
