An uplifting look at three famous and flawed fathers of the Christian church and how their lives can inspire us to fall in love with God and find the power to overcome our weaknesses. Augustine grappled with sexual passion. Martin Luther struggled to control his tongue. John Calvin fought the battle of faith with the world's weapons. Yet despite their failings, each man will always be remembered as a founding father to the Christian faith because of the messages they declared. And even with their deaths hundreds of years ago, their messages still speak today. John Piper explores each man's life, integrating Augustine's delight in God with Luther's emphasis on the Word and Calvin's exposition of Scriptures. Through their strengths and struggles, he teaches us how to better live today, for when we consider their lives, we behold the glory and majesty of God - and in that, find the power to overcome our weaknesses.
