Faith is essential to our spiritual growth, yet, too often, good Catholics hold misconceptions about faith's meaning or role - misconceptions that can lead to spiritual stagnation. In these pages, Fr. Wojciech Giertych, OP, theologian of the Papal Household, corrects prominent errors and clearly articulates what faith is, how it works, and how it may expand, or wither, within one's soul. Fr. Giertych's moving and practical reflections bring ancient wisdom to bear on our modern age, teaching what it really means to have and grow in faith. You'll also discover the role of prayer in the life of faith.
