Pope Francis says restless hearts these days are seeking sure answers to life's questions but don't find them.

Francis has voiced this reflection during Mass in St. Peter's Basilica Wednesday to mark Epiphany, which recalls the Gospel account of the Three Kings, or Magi, who follow a star to find the infant Jesus in Bethlehem.

The pontiff says the Catholic church is tasked with seeing and showing ever more clearly the desire for God which is present in the heart of every man and woman."

Francis says: "Like the Magi, countless people in our day have a 'restless heart' which continues to search without finding sure answers."

Recalling the long journey of the Magi, Francis says "before Jesus, all divisions of race, language and culture disappear."
