What if we taught young people that they can measure success by how they follow Christ rather than by how much money they make or where they go to college? In What Matters Most, University of Notre Dame theology professor Leonard J. DeLorenzo urges youth ministers, teachers, and parents to help young people redefine success in light of their call to discipleship-completely saying yes to God. In Luke's account of the Annunciation, Mary offers a true model of discipleship for young people to follow. Her example will empower them to make choices about how to live their lives as a courageous yes to God in everything they choose-just as she did. DeLorenzo, who served as the long-time director of Notre Dame Vision-a program designed to help young Catholics find their true calling as disciples of Jesus-shows how Mary exhibited four habits that will guide young people to make important life decisions.
