Is it possible that the life stories of believers are theological places where Christian revelation is updated? This text is a theological and hermeneutical exercise that interprets how the believer's life story is related in a friendly way with the Word of God. The first chapter interprets the existential structure of the life story to put it into dialogue with the narrative identity of Jesus Christ. The second chapter indicates how was constructed theologically the narrative identity of Jesus of Nazareth in Christianity. Finally, the third chapter analyzes how the experience of encounter with the God of Jesus Christ transforms the way in which the listener of the Word relates his existence for himself and for his ecclesial community.
