(1) 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 grace flow are opened. Let no soul fear to draw near to Me, even though its sins be as scarlet. Diary 699 [Note: confession does not have to be done on the Sunday itself. Beforehand is fine]
(2) Mankind will not have peace until it turns with trust to My Mercy. —St. Faustina’s Diary 300
(3) Let all mankind recognize My unfathomable mercy. It is a sign for the end times; after it will come the day of justice. Diary 848
(4) He who refuses to pass through the door of My mercy must pass through the door of My justice… Diary 1146
(5) Souls perish in spite of My bitter Passion. I am giving them the last hope of salvation; that is, the Feast of My Mercy. If they will not adore My mercy, they will perish for all eternity. Diary 965
(6) My Heart overflows with great mercy for souls, and especially for poor sinners. If only they could understand that I am the best of Fathers to them and that it is for them that the Blood and Water flowed from My Heart as from a fount overflowing with mercy. Diary 367
(7) These rays shield souls from the wrath of My Father. Happy is the one who will dwell in their shelter, for the just hand of God shall not lay hold of him. I desire that the first Sunday after Easter be the Feast of Mercy. Diary 299
(8) My daughter, write that the greater the misery of a soul, the greater its right to My mercy; [urge] all souls to trust in the unfathomable abyss of My mercy, because I want to save them all. Diary 1182
(9) The greater the sinner, the greater the right he has to My mercy. My mercy is confirmed in every work of My hands. He who trusts in My mercy will not perish, for all his affairs are Mine, and his enemies will be shattered at the base of My footstool. Diary 723
(10) [Let] the greatest sinners place their trust in My mercy. They have the right before others to trust in the abyss of My mercy. My daughter, write about My mercy towards tormented souls. Souls that make an appeal to My mercy delight Me. To such souls I grant even more graces than they ask. I cannot punish even the greatest sinner if he makes an appeal to My compassion, but on the contrary, I justify him in My unfathomable and inscrutable mercy. Diary 1146
(11) 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
(12) I desire trust from My creatures. Encourage souls to place great trust in My fathomless mercy. Let the weak, sinful soul have no fear to approach Me, for even if it had more sins than there are grains of sand in the world, all would be drowned in the unmeasurable depths of My mercy. Diary 1059
(13) I demand the worship of My mercy through the solemn celebration of the Feast and through the veneration of the image which is painted. By means of this image I shall grant many graces to souls. It is to be a reminder of the demands of My mercy, because even the strongest faith is of no avail without works. Diary 742
(14) Tell [all people], My daughter, that I am Love and Mercy itself. When a soul approaches Me with trust, I fill it with such an abundance of graces that it cannot contain them within itself, but radiates them to other souls. Jesus, Diary 1074
(15) 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
(16) I promise that the soul that will venerate this image will not perish. I also promise victory over [its] enemies already here on earth, especially at the hour of death. I Myself will defend it as My own glory. Jesus, Diary 48
(17) Souls who spread the honor of My mercy I shield through their entire lives as a tender mother her infant, and at the hour of death I will not be a Judge for them, but the Merciful Savior. At that last hour, a soul has nothing with which to defend itself except My mercy. Happy is the soul that during its lifetime immersed itself in the Fountain of Mercy, because justice will have no hold on it. Diary 1075
