St. Faustina Kowalska reported seeing a merciful Jesus, with beams of red and white light shining from his heart. In her diary, the cloistered mystic described a 1935 vision in which she was told the write down this prayer as protection from divine judgment: "Eternal Father, I offer You the Body and Blood, Soul and Divinity of Your dearly beloved Son, Our Lord Jesus Christ, in atonement for our sins and those of the whole world; for the sake of His sorrowful Passion, have mercy on us and on the whole world."
Some of the Sisters of Our Lady of Mercy thought the uneducated nun was unstable and the Vatican shunned her writings. But her visions impressed a young priest in nearby Krakow named Father Karol Wojtyla, who rose through the ranks from professor to bishop, archbishop and cardinal. Finally, he became Pope John Paul II.
The Polish pope was a champion of Faustina's "Divine Mercy" devotions. He testified: "The message of Divine Mercy has always been near and dear to me." In a sense, he said, it "forms the image of this pontificate." On April 30, 2000, John Paul II canonized her as St. Faustina.
It was in 1937, a year before she died of tuberculosis, the 32-year-old nun had another apocalyptic vision of Jesus.
She wrote: "As I was praying for Poland, I heard the words: I bear a special love for Poland, and if she will be obedient to My will, I will exalt her in might and holiness. From her will come forth the spark that will prepare the world for My final coming."
