Teaching to Change Lives is Howard Hendricks' distilled masterwork on the craft and calling of Christian education. Drawing on more than three decades of teaching at Dallas Theological Seminary—and a lifetime of watching God transform lives through ordinary communicators—Hendricks presents seven foundational principles he calls "The Seven Laws of the Teacher." The book is structured around a memorable acrostic, TEACHER, with each letter representing one law. Written with the storytelling warmth, practical directness, and spiritual urgency that defined his celebrated teaching ministry, this book has shaped the philosophy of Christian educators across generations. Hendricks's personal journey frames the entire work. Born into a broken home in north Philadelphia, he was reached by a sixth-grade-educated Sunday school teacher named Walt, who invested in him when no one else did. That experience—a humble, growing man pouring his life into a single child—became the template for everything Hendricks would teach about effective education. The book insists that teaching is never about technique alone; it is about transformation, and transformation begins in the teacher before it can ever reach the student.
