"It is God, who is rich in mercy whom Jesus Christ has revealed to us as Father: it is His very Son who, in Himself, has manifested Him and made Him known to us… It is especially for [sinners] that the Messiah becomes a particularly clear sign of God who is love, a sign of the Father. In this visible sign the people of our own time, just like the people then, can see the Father."
—St. John Paul II, Dives in misercordia (n.1)
"I desire that the whole world know My infinite mercy. I desire to grant unimaginable graces to those souls who trust in My mercy. [...] Do all you possibly can for this work of My mercy. I desire that My mercy be worshiped.”
— Words of Jesus to St. Faustina,  Diary (687, 998)
