St. Faustina
699 On one occasion, I heard these words: My daughter, tell the whole world about My inconceivable mercy. I desire that the Feast of Mercy be a refuge and shelter for all souls, and especially for poor sinners. On that day the very depths of My tender mercy are open. I pour out a whole ocean of graces upon those souls who approach the Fount of My Mercy. The soul that will go to Confession and receive Holy Communion shall obtain complete forgiveness of sins and punishment. On that day all the divine floodgates through which graces flow are opened. Let no soul fear to draw near to Me, even though its sins be as scarlet. My mercy is so great that no mind, be it of man or of angel, will be able to fathom it throughout all eternity. Everything that exists has come forth from the very depths of My most tender mercy. Every soul in its relation to Me will contemplate My love and mercy throughout eternity. The Feast of Mercy emerged from My very depths of tenderness. It is My desire that it be solemnly celebrated on the first Sunday after Easter. Mankind will not have peace until it turns to the Fount of My Mercy.
796 The Lord told me to say this chaplet for nine days before the Feast of Mercy. It is to begin on Good Friday. By this novena, I will grant every possible grace to souls.
1059 Jesus is commanding me to make a novena before the Feast of Mercy, and today I am to begin it for the conversion of the whole world and for the recognition of The Divine Mercy…. so that every soul will praise My goodness. I desire trust from My creatures. Encourage souls to place great trust in My fathomless mercy. Let the weak, sinful souls have no fear to approach Me, for even if it had more sins that there are grains of sand in the world, all would be drowned in the immeasurable depths of My mercy.
