This book is addressed to ordinary people who fight for their salvation, and tries to resolve some ambiguities by returning and approaching as best as possible the mystery of the Confession. Unfortunately, there is a great deal of ignorance, misinterpretation and distortion about this mystery. The mystery of repentance is a wonderful gift from God. And we ignore, despise, or misuse this gift, and as a result remain unliberated. By making a detailed analysis of the Parabolia of the Prodigal Son, the author helps us to better prepare for the meeting with God through repentance-confession.
