In clear and practical chapters, this spiritual classic calls ordinary Catholics to embrace the universal vocation to holiness with renewed purpose. It offers concrete guidance for growing in faith, hope, and charity through daily duties, small sacrifices, and faithful prayer. Addressing common sins, scrupulosity, forgiveness, and the formation of children, it also illuminates the cardinal virtues and the power of a simple daily examen. With pastoral wisdom and encouragement, this book shows how steadfast love of God in the ordinary circumstances of life leads to lasting joy and true sanctity.
