The Divine Mercy image is a depiction of Jesus based on a vision Saint Faustina Kowalska had. "I promise that the soul that will venerate this image will not perish," Jesus told Faustina, according to her diary, which has been studied and authenticated by the Church over several decades. "I also promise victory over enemies already here on earth, especially at the hour of death. I myself will defend it as My own glory." (Diary of Faustina, 48)
This image is based on the first image painted of the Divine Mercy. The first Divine Mercy image (painted by Eugeniusz Kazimirowski in 1934) at the Sanctuary of the Divine Mercy, Vilnius.
