This is what Pope Benedict XVI says:
« ... we might still wonder in our hearts whether it is really possible to live joyfully amid all life’s trials, especially those which are most tragic and mysterious. We wonder whether following the Lord and putting our trust in him will always bring happiness.
We can find an answer in some of the experiences of young people like yourselves who have found in Christ the light that can give strength and hope even in difficult situations.»
Then Pope Benedict XVI gives two examples:
Pier Giorgio Frassati and Chiara Badano.
Blessed Pier Giorgio Frassati (1901-1925) experienced many trials during his short life, including a romantic experience that left him deeply hurt. In the midst of this situation he wrote to his sister: “You ask me if I am happy. How could I not be? As long as faith gives me strength, I am happy. A Catholic could not be other than happy... The goal for which we were created involves a path which has its thorns, but it is not a sad path. It is joy, even when it involves pain” (Letter to his sister Luciana, Turin, 14 February 1925).
Closer to us in time is Chiara Badano (1971-1990), who was recently beatified. She experienced how pain could be transfigured by love and mysteriously steeped in joy. At the age of eighteen, while suffering greatly from cancer, Chiara prayed to the Holy Spirit and interceded for the young people of the movement to which she belonged. As well as praying for her own cure, she asked God to enlighten all those young people by his Spirit and to give them wisdom and light. “It was really a moment of God’s presence. I was suffering physically, but my soul was singing” (Letter to Chiara Lubich, Sassello, 20 December 1989). The key to her peace and joy was her complete trust in the Lord and the acceptance of her illness as a mysterious expression of his will for her sake and that of everyone. She often said: “Jesus, if you desire it, then I desire it too”.
