In a confused world with moral decay, we need clear direction for godly living. While the mention of holiness is not commonly heard these days, the Psalms call us to cultivate holy lives in today's society. The psalmists not only teach us how to grow in holiness but they draw us into their own rich experiences. The author explores the Psalms to give us a perspective on the nature of holiness and the many important ways we can grow in holiness. The Psalter serves as an invaluable guide for our spiritual formation as followers of Jesus Christ.
