We were seeking the answers on the questions: What is Sin? What and according to which rules is guilty? What mean forgiveness and reconciliation? What does it mean the need of forgivness, forgiving others and ourselves, seeking to restore a relationship, receiving forgiveness, freedom from guilt and sin, and a clean conscience? To this goog use we have put some films, stories of the school of hard knocks, biblical stories, theological-ethical reflexion and music.
