When Augustine handed over the leadership of his church in AD 426, his successor was so overwhelmed by a sense of inadequacy that he declared, "The swan is silent," fearing the spiritual giant's voice would be lost in time. But for 1,600 years Augustine has not been silent--and neither have the men who faithfully trumpeted the cause of Christ after him. This book compiles all 7 volumes in his Swans Are Not Silent series, in which John Piper explores the lives of Christians who have inspired every generation of believers toward a greater passion for God. Focusing on 21 leaders from church history, this book offers a close look at the course of their individual lives and their impact on our own spirituality today.
