The Reformation swept across Europe with a God-glorifying gospel of grace. Now the doctrine of grace cherished and proclaimed by the Reformers is under renewed assault from an unexpected place—the evangelical church itself. With the help of several theologians, Gary L. W. Johnson and Guy P. Waters trace the background and development of two seemingly disparate movements that have surfaced within the contemporary church-the New Perspective(s) on Paul and the Federal Vision-and how they corrupt the truth of salvation by faith alone. By regaining a focus on the doctrine of grace, pastors, seminarians, and future leaders can regain the cohesion, coherence, and direction to truly build the church to withstand the attacks of false and empty doctrines.
