Â My daughter, tell the whole world about My inconceivable mercy. I desire that the Feast of MercyÂ 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 grace 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. (St. Faustina’s Diary 699)
The next morning, when I entered chapel, I heard these words interiorly:Â Every time you enter the chapel, immediately recite the prayer which I taught you yesterday.Â When I had said the prayer, in my soul I heard these words:Â This prayer will serve to appease My wrath. You will recite it for nine days, on the beads of the rosary, in the following manner:
First of all, you will say one OUR FATHER and HAIL MARY and the I BELIEVE IN GOD.
Then on the OUR FATHER beads you will say the following words:Â “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.”
On the HAIL MARY beads you will say the following words:Â “For the sake of His sorrowful Passion have mercy on us and on the whole world.”
In conclusion, three times you will recite these words:Â “Holy God, Holy Mighty One, Holy Immortal One, have mercy on us and on the whole world.” (St. Faustina’s Diary 476)
