World Youth Day is the largest gathering of people in the world. It happens every three years or so, at the invitation of the Pope. It is an invitation to pilgrimage, to make a physical journey, and a spiritual one. During that week-long journey, Matt was asked to sing "Lord I Need You" in front of 3 million people during a time of Eucharistic Adoration.
