THE DIVINE MERCY CHAPLET CARD For the sake of His sorrowful Passion, have mercy on us and on the whole world. Throughout the 1930's, Jesus appeared to St. Faustina, a sister of the Our Lady of Mercy order. St. Faustina wrote down everything that Jesus told her, this work is published as the Diary of St. Faustina. He urged her to pray for mercy, "Even if there were a sinner most hardened, if he were to recite this Chaplet only once, he would receive grace from My infinite mercy. I desire to grant unimaginable graces to those souls who trust in My mercy. Through the Chaplet you will obtain everything, if what you ask for is compatible with My will.
