With the emphasis on Divine Mercy Sunday and Jesus’ promise of a complete remission of sin and punishment following his directives as told to St. Faustina and ratified by St. John Paul II, we should also recall companion revelations Jesus gave her. Here are 15 from her diary, Divine Mercy in My Soul, to take to heart. Be mindful especially of trusting (not doubting), being merciful, believing in Jesus’ limitless mercy, the sacraments and more.

First, a brief review of Divine Mercy Sunday’s devotion promises.

Jesus emphasized: “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). He also 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 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 (699).

Here are more revelations, promises, cautions and explanations of his immeasurable mercy that Jesus told to Faustina his secretary.

1. “Souls who spread the honor of My mercy I shield through their entire life” (998).

2. “The flames of mercy are burning Me — clamoring to be spent; I want to keep pouring them out upon souls; souls just don’t want to believe in My goodness” (177).

3. “The graces of My mercy are drawn by means of one vessel only, and that is — trust. The more a soul trusts, the more it will receive” (1578).

4. “My child, all your sins have not wounded My Heart as painfully as your present lack of trust does — that after so many efforts of My love and mercy, you should still doubt My goodness” (1486).

5. “Oh, if sinners knew My mercy, they would not perish in such great numbers. Tell sinful souls not to be afraid to approach Me; speak to them of My great mercy. The Lord said to me, The loss of each soul plunges Me into mortal sadness. You always console Me when you pray for sinners. The prayer most pleasing to Me is prayer for the conversion of sinners” (1396-97).

6. A daily reminder. “At three o’clock, implore My mercy, especially for sinners; and, if only for a brief moment, immerse yourself in My Passion, particularly in My abandonment at the moment of agony. This is the hour of great mercy for the whole world. … In this hour, I will refuse nothing to the soul that makes a request of me in virtue of My Passion” (1320).

7. “I need sacrifice lovingly accomplished, because that alone has meaning for Me. Enormous indeed are the debts of the world which are due to Me; pure souls can pay them by their sacrifice, exercising mercy in spirit. … [W]rite this for the many souls who are often worried because they do not have the material means with which to carry out an act of mercy. Yet spiritual mercy, which requires neither permission nor storehouses, is much more meritorious and is within the grasp of every soul. If a soul does not exercise mercy somehow or other, it will not obtain My mercy on the day of judgment. Oh, if only souls knew how to gather eternal treasure for themselves, they would not be judged, for they would forestall My judgment with their mercy” (1316-17). “As for you, be always merciful toward other people, and especially toward sinners” (1446).

8. “Oh, how painful it is to Me that souls so seldom unite themselves to Me in Holy Communion. I wait for souls, and they are indifferent toward Me. I love them tenderly and sincerely, and they distrust Me. I want to lavish My graces on them, and they do not want to accept them. They treat Me as a dead object, whereas My Heart is full of love and mercy. In order that you may know at least some of My pain, imagine the most tender of mothers who has great love for her children, while those children spurn her love. Consider her pain. No one is in a position to console her. This is but a feeble image and likeness of My love.

“Write, speak of My mercy. Tell souls where they are to look for solace; that is, in the Tribunal of Mercy [the Sacrament of Reconciliation] There the greatest miracles take place [and] are incessantly repeated. To avail oneself of this miracle, it is not necessary to go on a great pilgrimage or to carry out some external ceremony; it suffices to come with faith to the feet of My representative and to reveal to him one’s misery, and the miracle of Divine Mercy will be fully demonstrated. Were a soul like a decaying corpse so that from a human standpoint, there would be no [hope of] restoration and everything would already be lost, it is not so with God. The miracle of Divine Mercy restores that soul in full. Oh, how miserable are those who do not take advantage of the miracle of God’s mercy! You will call out in vain, but it will be too late” (1447-1448).

9. “As often as you hear the clock strike the third hour, immerse yourself completely in My mercy, adoring and glorifying it; invoke its omnipotence for the whole world, and particularly for poor sinners; for at that moment mercy was opened wide for every (145) soul. In this hour you can obtain everything for yourself and for others for the asking; it was the hour of grace for the whole world — mercy triumphed over justice.”

10. “How painfully distrust of My goodness wounds Me! Sins of distrust wound Me most painfully” (1076).

11. “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. Secretary of My mercy, write, tell souls about this great mercy of Mine, because the awful day, the day of My justice, is near” (965).

12. “Before I come as the Just Judge, I am coming first as the King of Mercy. Before the day of justice arrives, there will be given to people a sign in the heavens of this sort: All light in the heavens will be extinguished, and there will be great darkness over the whole earth. Then the sign of the cross will be seen in the sky, and from the openings where the hands and the feet of the Savior were nailed will come forth great lights which will light up the earth for a period of time. This will take place shortly before the last day” (83).

13. “I do not want to punish aching mankind, but I desire to heal it, pressing it to My Merciful Heart. I use punishment when they themselves force Me to do so; My hand is reluctant to take hold of the sword of justice. Before the Day of Justice I am sending the Day of Mercy” (1588).

14. “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. Write: before I come as a just Judge, I first open wide the door of My mercy. He who refuses to pass through the door of My mercy must pass through the door of My justice …” (1146).

15. “Tell the world about My mercy and My love. The flames of mercy are burning me. I desire to pour them out upon human souls. Oh, what pain they cause Me when they do not want to accept them! … Tell aching mankind to snuggle close to My merciful Heart, and I will fill it with peace. 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” (1074).

“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” (1075).

16. “The mercy of God, hidden in the Blessed Sacrament, the voice of the Lord who speaks to us from the throne of mercy: Come to Me, all of you. Jesus: Be not afraid of your Savior; O sinful soul. I make the first move to come to you, for I know that by yourself you are unable to lift yourself to me. Child, do not run away from your Father; be willing to talk openly with your God of mercy who wants to speak words of pardon and lavish his graces on you. How dear your soul is to Me! I have inscribed your name upon My hand; you are engraved as a deep wound in My Heart.

(Then Jesus answers a Soul’s fears) “My child, do you fear the God of mercy? My holiness does not prevent Me from being merciful. Behold, for you I have established a throne of mercy on earth — the tabernacle — and from this throne I desire to enter into your heart. I am not surrounded by a retinue or guards. You can come to me at any moment, at any time; I want to speak to you and desire to grant you grace.

“My mercy is greater than your sins and those of the entire world. Who can measure the extent of my goodness? For you I descended from heaven to earth; for you I allowed myself to be nailed to the cross; for you I let my Sacred Heart be pierced with a lance, thus opening wide the source of mercy for you. Come, then, with trust to draw graces from this fountain. I never reject a contrite heart. Your misery has disappeared in the depths of My mercy. Do not argue with Me about your wretchedness. You will give me pleasure if you hand over to me all your troubles and griefs. I shall heap upon you the treasures of My grace” (1485).

17. “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 unmeasurable depths of My mercy (1059). … I am more generous toward sinners than toward the just. It was for their sake that I came down from heaven; it was for their sake that My Blood was spilled. Let them not fear to approach Me; they are most in need of My mercy (1275). … I am Love and Mercy Itself. There is no misery that could be a match for My mercy, neither will misery exhaust it, because as it is being granted — it increases. The soul that trusts in My mercy is most fortunate, because I Myself take care of it” (1273).
