This volume contains 21 sermons on the spiritual life by the great 19th century theologian and churchman, Saint Philaret of Moscow, and here translated into English from Russian for the first time. Archimandrite Zacharias writes in the Introduction that St. Philaret's word is "not the word of man but the word of God, which 'effectually worketh in them that believe.'" He continues, "Saint Philaret was a sign of God for his generation, providing a word for his contemporaries and an answer to all their existential problems." This thematic collection taken from the Saints complete works cover such important topics on the spiritual life as: On Being Born Again, On the Fear of God, On Gratitude to God, On the Purification of the Heart, On Love of Work, On the Lord's Prayer, On Praying with the Spirit and the Understanding, On Our Citizenship in Heaven, and more.
