In this unique work, Peter Kreeft brings together 358 useful, everyday insights from St. Thomas Aquinas' masterpiece the Summa Theologiae. He pairs these easily digestible quotes from the Summa with his own delightfully written commentary in order to answer the kinds of questions real people ask their spiritual directors. These 358 passages from the Summa have helped Kreeft in his own struggles to grow closer to the Lord. His practical, personal, and livable advice is the fruit of his labors to apply the insights of Aquinas to his own quest for sanctity, happiness, and union with God.
