Once a famous Moscow priest was asked how our confession in church is accepted by God? The priest replied that confession is accepted by the priest, not God. But God needs our repentance. And it is very important when a person can see his sins himself and tell them in confession. But does everyone know what they need to “take up arms against” in themselves? The proposed book will help all those who are preparing for the Sacrament of Confession and would like to bring worthy fruits of repentance. When compiling and preparing the text, material from the book of Archpriest Vasily Mikhailovsky “Full Confession” was used.
