This is a reprint of a spiritual classic which, as stated by the author, “is not an expression of a theory but a practical guide of souls”. Each chapter gives an explanation of a passage taken from Sacred Scripture which dwells on the central idea of surrendering one’s will to the will of God. It is aimed at increasing in the reader his love for and acceptance to the will of God, which is best expressed in developing human virtues as patience, suffering, examination of conscience and an incessant love for the Holy Mass, prayer, devotion to Our Lady, etc.
