This is the official prayer written for pilgrims to the 2016 World Youth Day, in Krakow, Poland:
"God, merciful Father,
in your Son, Jesus Christ, you have revealed your love
and poured it out upon us in the Holy Spirit, the Comforter,
We entrust to you today the destiny of the world and of every man and woman”.
We entrust to you in a special way
young people of every language, people and nation:
guide and protect them as they walk the complex paths of the world today
and give them the grace to reap abundant fruits
from their experience of the Krakow World Youth Day.
Heavenly Father,
grant that we may bear witness to your mercy.
Teach us how to convey the faith to those in doubt,
hope to those who are discouraged,
love to those who feel indifferent,
forgiveness to those who have done wrong
and joy to those who are unhappy.
Allow the spark of merciful love
that you have enkindled within us
become a fire that can transform hearts
and renew the face of the earth.
Mary, Mother of Mercy, pray for us.
Saint John Paul II, pray for us.
Saint Faustina, pray for us."
