 Jesus told St. Faustina that this Feast of Mercy would be a very        special day when "all the divine floodgates through which graces        flow are opened". (Diary 699) Our Lord made a great promise to all        those souls who would go to Confession and then receive Him in Holy        Communion on the Feast of Mercy, on the Sunday after Easter, which is now        called Divine Mercy Sunday throughout the Catholic Church.

Jesus promised that "The soul that will go to Confession and receive        Holy Communion shall obtain the complete forgiveness of sins and        punishment."(Diary 699) He went on to say "I want to grant a        complete pardon to the souls that will go to Confession and receive Holy        Communion on the Feast of My Mercy." (Diary 1109) 
We want to encourage everyone to take advantage of this incredible        promise and the additional Plenary Indulgence on this great Feast of Mercy        "Divine Mercy Sunday". We want you to benefit fully from these promises,        and we also want you to notify all of your family and friends about them        too and urge them to return to the practice of their faith!
The Image of The Divine Mercy, which Our Lord requested to be solemnly        blessed and venerated on this day, will be on display in our church. Pope        John Paul II said that the image portrays the Risen Jesus Christ bringing        Mercy to the whole world. Our Lord said "I want the image to be        solemnly blessed on the first Sunday after Easter, and I want it to be        venerated publicly so that every soul may know about it. I promise        that the soul that will venerate this image will not perish". (Diary        341, 48) Please take the time to visit with this Image of The Divine Mercy        and venerate Jesus.
Jesus said to St. Faustina "I am offering people a vessel with which        they are to keep coming for graces to the fountain of mercy. That vessel        is this image with the signature: Jesus, I trust in You". (Diary 327)       "The two rays denote Blood and Water. The pale ray stands for the Water        which makes souls righteous. The red ray stands for the Blood which is the        life of souls. These two rays issued forth from the very depths of My        tender mercy when My agonized Heart was opened by a lance on the cross.        …Happy is the one who will dwell in their shelter, for the just hand of        God shall not lay hold of him." (Diary 299)
  
  
About the feastday "Divine Mercy Sunday", Jesus said "…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 poor sinners. On        that day the very depths of My tender mercy are open. I pour out a whole        ocean of graces upon the souls who approach the Fount of My Mercy. 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....        Mankind will not have peace until it turns to the Fount of My Mercy".        (Diary 699)
Our Lord said "When you go to confession, to this fountain of My        mercy, the Blood and Water which came forth from My Heart always flows        down upon your soul…" and "Every time you go to confession, immerse        yourself entirely in My mercy with great trust, so that I may pour the        bounty of My grace upon your soul. When you approach the confessional,        know this, that I Myself am waiting there for you. I am only hidden by the        priest, but I Myself act in your soul. Here the misery of the soul meets        the God of mercy" (1602) Make your confession before Me. The        person of the priest is… only a screen. Never analyze what sort of a        priest that I am making use of; open your soul in confession to Me, and I        will fill it with My light." (1725)
It is required of all Catholics to confess their serious sins at least        once every year. If you haven’t yet met this obligation then take        advantage of this outstanding opportunity to receive an outpouring of an        ocean of graces that Jesus promises on this day. Those who have already        confessed their sins should make room for others. 
The Church allows for one to go to Confession for up to about 20 days,        before or after Divine Mercy Sunday.
