Drawing from the rich Catholic tradition of spirituality, Dr. Anthony Lilles presents prayer as a living dialogue that transforms the whole of life. With guidance from the saints and mystics, he shows how humble, persevering prayer leads to a deeper awareness of God’s presence and prepares the soul for purification, spiritual battle, and even the dark night. Addressing practical challenges such as dryness, self deception, and busyness, this book invites readers to entrust themselves to Christ, rely on the help of Our Lady, and pursue the heroic holiness to which they are called.
