In Manly Piety in Its Spirit, celebrated religious writer Robert Philip explores the true meaning and expression of Christian devotion for men. Philip argues that modern notions of masculinity and piety have become unnaturally separated, leading to a version of faith that fails to resonate with many men. Throughout this thought-provoking book, Philip lays out his vision for bringing devotion and manliness back together. He examines the lives of great biblical and historical figures who modeled genuine "manly piety," such as Moses, David, and Jesus Christ himself. According to Philip, their examples show that qualities like courage, leadership, justice, and self-sacrifice for a greater cause are integral parts of a godly masculinity. Philip then provides practical guidance for how modern men can live out an active, vigorous faith. He offers insights for spiritual disciplines and habits ranging from prayer and Bible study, to integrity in business, service to others, defense of the helpless, and stewardship of God's creation. Philip contends that when lived fully and boldly, biblical Christianity uniquely satisfies the longings and calling innate in manhood.

Written in the engaging and intellectual style that made Philip famous, Manly Piety in Its Spirit makes the case that true masculinity reaches its potential and fulfillment only through a vigorous, practical, and heroic faith. It is an inspiring call to men of all walks to embrace Christian discipleship with energy and conviction, utilizing their gifts and abilities in service to God's Kingdom.
