God's mercy can make even the driest land become a garden, can restore life to dry bones (cf. Ez 37:1-14). ... Let us be renewed by God's mercy, let us be loved by Jesus, let us enable the power of his love to transform our lives too; and let us become agents of this mercy, channels through which God can water the earth, protect all creation and make justice and peace flourish.
Note that this Pope Francis quotation is from 2013, two years before the opening of the Jubilee. Mercy is at the heart of his understanding of the Gospel and of pastoral life.
