The devotion to Jesus as the Divine Mercy is based on the writingsof Saint Faustina, a Polish nun who wrote a diary of about 600pages recording the revelations she received about God's mercy.Jesus looked at me and said, Souls perish in spite of My bitterPassion. I am giving them the last hope of salvation; that is, theFeast of My Mercy. If they will not adore My mercy, they willperish for all eternity. Secretary of My mercy, write, tell soulsabout this great mercy of Mine, because the awful day, the day ofMy justice, is near. (Diary - Divine Mercy in My Soul, 965)
