The Lord “gave up his spirit” (cf. Mt 27:50) on a cross when he was little more than thirty years of age (cf. Lk 3:23). It is important to realize that Jesus was a young person. He gave his life when he was, in today’s terms, a young adult. He began his public mission in the prime of life, and thus “a light dawned” (Mt 4:16) that would shine most brightly when he gave his life to the very end. That ending was not something that simply happened; rather, his entire youth, at every moment, was a precious preparation for it. “Everything in Jesus’s life was a sign of his mystery”; indeed, “Christ’s whole life is a mystery of redemption”.
The Gospel tells us nothing of Jesus’ childhood, but it does recount several events of his adolescence and youth. Matthew situates the time of the Lord’s youth between two events: his family’s return to Nazareth after their exile, and Jesus’ baptism in the Jordan, the beginning of his public ministry. The last images we have of Jesus as a child are those of a tiny refugee in Egypt (cf. Mt 2:14-15) and repatriated in Nazareth (cf. Mt 2:19-23). Our first image of Jesus as a young adult shows him standing among the crowds on the banks of the Jordan river to be baptized by his kinsman John the Baptist, just like any other member of his people (cf. Mt 3:13-17).
Jesus’ baptism was not like our own, which introduces us to the life of grace, but a consecration prior to his embarking on the great mission of his life. The Gospel says that at his baptism the Father rejoiced and was well pleased: “You are my beloved Son” (Lk 3:22). Jesus immediately appeared filled with the Holy Spirit, and was led by the Spirit into the desert. There he prepared to go forth to preach and to work miracles, to bring freedom and healing (cf. Lk 4:1-14). Every young person who feels called to a mission in this world is invited to hear the Father speaking those same words within his or her heart: “You are my beloved child”.
