Encounters of the young with the Pope indicate an undiscovered source of power which characterises the faith of young people. The article is a reflection on the meaning of faith which helps to rediscover and use the dynamism inherent in the young. The conclusion is that faith opens a man to an invisible reality of God's sacramental grace and the strengthening and deepening function of the sacraments. Faith and sacraments are closely connected which results in an integral growth of a young man opening himself to God and His action. Faith that expresses itself in a personal relationship between a young man and God is realized and takes its final shape in the community of the Church.
