St. Alphonsus was filled with a great zeal for souls. His eloquent sermons, wise teachings, and kindness as a confessor won many souls for Christ. "In God you possess the most exalted and supreme Lord," he wrote in his book How to Pray at All Times (1753), "but also a Friend who loves you with the greatest possible love. He is not offended--on the contrary He is pleased--when you treat Him with that confidence, freedom, and tenderness with which a child treats its mother." Through his inspiring words and instructive teaching, St. Alphonsus's enduring works continue to show souls how to develop such friendship with God.
