"The most dangerous thing about sin is that it means a separation from God: being cut off from Him in one’s love, in one’s will and in one’s activity. It is to be parted from Him on Earth and in Heaven. What is the story of this rift between God and man? What does it mean to return to God? How does one return to God? What is the central role of prayer in the return to God? This book will tell you about all these things." (His Holiness Pope Shenouda III, Pope and Patriarch of the Coptic Orthodox Church)
