Divine Mercy Shrine, Krakow, Poland

A humble Polish nun, St. Faustina received extraordinary revelations in the 1930s, which she recorded in her diary.
Our Lord told her, “In the Old Covenant I sent prophets wielding thunderbolts to My people. Today I am sending you with My mercy to the people of the whole world. I do not want to punish aching mankind, but I desire to heal it, pressing it to My Merciful Heart” (Diary of Saint Maria Faustina Kowalska, 1588).
Jesus specially chose her for the mission of bringing His message of Mercy to the world, and He called Divine Mercy Sunday mankind’s “last hope of salvation” (995).
