Piper's brief biographies of Athanasius, Owen, and Machen tell the stories of great men who passionately defended the truth of the gospel, despite many struggles and much suffering. Athanasius, John Owen, and J. Gresham Machen stood for the truth of God's Word in the face of opposition-all out of a deep love for Christ and a desire for others to know God in his fullness. These men were willing to suffer for the sake of guarding the sanctity of the gospel. They faced many threats, years of exile, the deaths of loved ones, opposition from friends and authorities, and sickness and pain. Yet they passionately maintained their zeal for Christ himself and steadfastly defended the gospel. In this fourth book of The Swans Are Not Silent series, John Piper delivers concise biographies of these great men. He shows how a bishop, pastor, and seminary founder each emulated personal holiness, despite adversity and affliction. Readers will be encouraged and emboldened from the stories of these soldiers who defended truth for the sake of the cross. Now available in paperback.
