Simply changing our habits, Luther saw, will not deal with those deeper, sinful inclinations. What we need is a radical renewal—not self-improvement but a profound change of heart—so that we want and love and long differently. We need hearts that freely love and are pleased with God (Ezek. 36:26–27; Mark 7:14–23; John 3:3). “How shall a work please God if it proceeds from a reluctant and resisting heart?” asked Luther.
