Saint Faustina and the Sacred Heart
In honor of the feast of the Sacred Heart, we decided to share with you some passages from St. Faustina's Diary on Jesus' Heart.
O Eternal Love, You command Your Sacred Image to be painted
And reveal to us the inconceivable fount of mercy,
You bless whoever approaches Your rays,
And a soul all black will turn into snow.
O sweet Jesus, it is here You established the throne of Your mercy
To bring joy and hope to sinful man.
From Your open Heart, as from a pure fount,
Flows comfort to a repentant heart and soul.
May praise and glory for this Image
Never cease to stream from man's soul.
May praise of God's mercy pour from every heart
Now, and at every hour, and forever and ever. — Diary, 1
O Jesus, eternal Truth, our Life, I call upon You and I beg Your mercy for poor sinners. O sweetest Heart of my Lord, full of pity and unfathomable mercy, I plead with You for poor sinners. O Most Sacred Heart, Fount of Mercy from which gush forth rays of inconceivable graces upon the entire human race, I beg of You light for poor sinners. O Jesus, be mindful of Your own bitter Passion and do not permit the loss of souls redeemed at so dear a price of Your most precious Blood. O Jesus, when I consider the great price of Your Blood, I rejoice at its immensity, for one drop alone would have been enough for the salvation of all sinners. Although sin is an abyss of wickedness and ingratitude, the price paid for us can never be equalled. Therefore, let every soul trust in the Passion of the Lord, and place its hope in His mercy. God will not deny His mercy to anyone. Heaven and earth may change, but God's mercy will never be exhausted. Oh, what immense joy burns in my heart when I contemplate Your incomprehensible goodness, O Jesus! I desire to bring all sinners to Your feet that they may glorify Your mercy throughout endless ages. — Diary,72
Suddenly, when I had consented to the sacrifice with all my heart and all my will, God's presence pervaded me. My soul became immersed in God and was inundated with such happiness that I cannot put in writing even the smallest part of it. I felt that His Majesty was enveloping me. I was extraordinarily fused with God. I saw that God was well pleased with me and, reciprocally, my spirit drowned itself in Him. Aware of this union with God, I felt I was especially loved and, in turn, I loved with all my soul. A great mystery took place during that adoration, a mystery between the Lord and myself. It seemed to me that I would die of love [at the sight of] His glance. I spoke much with the Lord, without uttering a single word. And the Lord said to me, You are the delight of My Heart; from today on, every one of your acts, even the very smallest, will be a delight to My eyes, whatever you do. At that moment I felt transconsecrated. My earthly body was the same, but my soul was different; God was now living in it with the totality of His delight. This is not a feeling, but a conscious reality that nothing can obscure. — Diary, 137.
A great mystery has been accomplished between God and me. Courage and strength have remained in my soul. When the time of adoration came to an end, I came out and calmly faced everything I had feared so much before. When I came out into the corridor, a great suffering and humiliation, at the hands of a certain person, was awaiting me. I accepted it with submission to a higher will and snuggled closely to the Most Sacred Heart of Jesus, letting Him know that I was ready for that for which I had offered myself.
Suffering seemed to spring out of the ground. Even Mother Margaret herself was surprised. For others, many things passed unnoticed, for indeed it wasn't worth paying any attention to them; but in my case, nothing passed unnoticed; each word was analyzed, each step watched. One sister said to me, "Get ready, Sister, to receive a small cross at the hands of Mother Superior. I feel sorry for you." But as for me, I rejoiced at this in the depths of my soul and had been ready for it for a long time. When she saw my courage, she was surprised. I see now that a soul cannot do much of itself, but with God it can do all things. Behold what God's grace can do. Few are the souls that are always watchful for divine graces, and even fewer of such souls who follow those inspirations faithfully. — Diary, 138
Renewal of vows. From the moment I woke up in the morning, my spirit was totally submerged in God, in that ocean of love. I felt that I had been completely immersed in Him. During Holy Mass, my love for Him reached a peak of intensity. After the renewal of vows and Holy Communion, I suddenly saw the Lord Jesus, who said to me with great kindness, My daughter, look at My merciful Heart. As I fixed my gaze on the Most Sacred Heart, the same rays of light, as are represented in the image as blood and water, came forth from it, and I understood how great is the Lord's mercy. And again Jesus said to me with kindness, My daughter, speak to priests about this inconceivable mercy of Mine. 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. Suddenly Jesus disappeared. But throughout that whole day my spirit remained immersed in God's tangible presence, despite the buzz and chatter that usually follow a retreat. It did not disturb me in the least. My spirit was in God, although externally I took part in the conversations and even went to visit Derdy. — Diary, 177
I am beginning the retreat today, Jesus, my Master, guide me. Govern me according to Your will, purify my love that it may be worthy of You, do with me as Your most merciful Heart desires. Jesus, there will be just the two of us during these days until the moment of our union. Keep me, Jesus, in a recollected spirit! — Diary, 218
O living Host, my one and only strength, fountain of love and mercy, embrace the whole world, fortify faint souls. Oh, blessed be the instant and the moment when Jesus left us His most merciful Heart! — Diary, 223
To suffer without complaining, to bring comfort to others and to drown my own sufferings in the most Sacred Heart of Jesus! ... — Diary, 224
Once the Lord said to me, Act like a beggar who does not back away when he gets more alms [than he asked for], but offers thanks the more fervently. You too, should not back away and say that you are not worthy of receiving greater graces when I give them to you. I know you are unworthy, but rejoice all the more and take as many treasures from My Heart as you can carry, for then you will please Me more. And I will tell you one more thing — take these graces not only for yourself, but also for others; that is, encourage the souls with whom you come in contact to trust in My infinite mercy. Oh, how I love those souls who have complete confidence in Me — I will do everything for them. — Diary, 294
O my Jesus, my only hope, thank You for the book which You have opened before my soul's eyes. That book is Your Passion which You underwent for love of me. It is from this book that I have learned how to love God and souls. In this book there are found for us inexhaustible treasures. O Jesus, how few souls understand You in Your martyrdom of love! Oh, how great is the fire of purest love which burns in Your Most Sacred Heart! Happy the soul that has come to understand the love of the Heart of Jesus! — Diary, 304
When I become immersed in the Lord's Passion, I often see the Lord Jesus, during adoration, in this manner: after the scourging, the torturers took the Lord and stripped Him of His own garment, which had already adhered to the wounds; as they took it off, His wounds reopened; then they threw a dirty and tattered scarlet cloak over the fresh wounds of the Lord. The cloak, in some places, barely reached His knees. They made Him sit on a piece of beam. And then they wove a crown of thorns, which they put on His sacred head. They put a reed in His hand and made fun of Him, bowing to Him as to a king. Some spat in His face, while others took the reed and struck Him on the head with it. Others caused Him pain by slapping Him; still others covered His face and struck Him with their fists. Jesus bore all this with meekness. Who can comprehend Him — comprehend His suffering? Jesus' eyes were downcast. I sensed what was happening in the most sweet Heart of Jesus at that time. Let every soul reflect on what Jesus was suffering at that moment. They tried to outdo each other in insulting the Lord. I reflected: Where does such malice in man come from? It is caused by sin. Love and sin have met. — Diary, 408
March 21, 1935. Often during Mass, I see the Lord in my soul; I feel His presence which pervades my being. I sense His divine gaze; I have long talks with Him without saying a word; I know what His divine Heart desires, and I always do what will please Him the most. I love Him to distraction, and I feel that I am being loved by God. At those times, when I meet with God deep within myself, I feel so happy that I do not know how to express it. Such moments are short, for the soul could not bear it for long, as separation from the body would be inevitable. Though these moments are very short, their power, however, which is transmitted to the soul, remains with it for a very long time. Without the least effort, I experience the profound recollection which then envelops me — and it does not diminish even if I talk with people, nor does it interfere with the performance of my duties. I feel the constant presence of God without any effort of my soul. I know that I am united with Him as closely as a drop of water is united with the bottomless ocean ... — Diary, 411
Once when my confessor [Father Sopocko] was saying Mass, I saw, as usual, the Child Jesus on the altar, from the time of the Offertory. However, a moment before the Elevation, the priest vanished from my sight, and Jesus alone remained. When the moment of the Elevation approached, Jesus took the Host and the chalice in His little hands and raised them together, looking up to heaven, and a moment later I again saw my confessor. I asked the Child Jesus where the priest had been during the time I had not seen him. Jesus answered, In My Heart. But I could not understand anything more of these words of Jesus. — Diary, 442
When we went to the Jesuits' place for the procession of the Sacred Heart, during Vespers I saw the same rays coming forth from the Sacred Host, just as they are painted in the image. My soul was filled with great longing for God.—Diary, 657
January 29, 1937. I overslept today. A little longer, and I would have been too late for Holy Communion because the chapel is a good distance from our section. When I went outdoors, the snow was knee-deep. But before it occurred to me that the doctor would not have allowed me to go out in such snow, I had already come to the Lord in the chapel. I received Holy Communion and was back in no time. I heard these words in my soul: My daughter, rest close to My Heart. Known to Me are your efforts. My soul is more joyful when I am close to the Heart of my God. — Diary, 902
In difficult moments, I will fix my gaze upon the silent Heart of Jesus, stretched upon the Cross, and from the exploding flames of His merciful Heart, will flow down upon me power and strength to keep fighting. — Diary, 906
O Jesus, how sorry I feel for poor sinners. Jesus, grant them contrition and repentance. Remember Your own sorrowful Passion. I know Your infinite mercy and cannot bear it that a soul that has cost You so much should perish. Jesus, give me the souls of sinners; let Your mercy rest upon them. Take everything away from me, but give me souls. I want to become a sacrificial host for sinners. Let the shell of my body conceal my offering, for Your Most Sacred Heart is also hidden in a Host, and certainly You are a living sacrifice.
Transform me into Yourself, O Jesus, that I may be a living sacrifice and pleasing to You. I desire to atone at each moment for poor sinners. The sacrifice of my spirit is hidden under the veil of the body; the human eye does not perceive it, and for that reason it is pure and pleasing to You. O my Creator and Father of great mercy, I trust in You, for You are Goodness Itself. Souls, do not be afraid of God, but trust in Him, for He is good, and His mercy is everlasting. — Diary, 908
... Divine Mercy, which flowed out from the open wound of the Heart of Jesus, I trust in You.
Divine Mercy, enclosed in the Heart of Jesus for us, and especially for sinners, I trust in You ... — Diary, 949
Today, I took part in a one-day retreat. When I was at the last conference, the priest was speaking of how much the world needs God's mercy, and that this seems to be a special time when people have great need of prayer and God's mercy. Then I heard a voice in my soul: These words are for you. Do all you possibly can for this work of My mercy. I desire that My mercy be worshiped, and I am giving mankind the last hope of salvation; that is, recourse to My mercy. My Heart rejoices in this feast. After these words, I understood that nothing can dispense me from the obligation which the Lord demands from me. — Diary, 998
June 4. Today is the Feast of the Most Sacred Heart of Jesus. During Holy Mass, I was given the knowledge of the Heart of Jesus and of the nature of the fire of love with which He burns for us and of how He is an Ocean of Mercy. Then I heard a voice: Apostle of My mercy, proclaim to the whole world My unfathomable mercy. Do not be discouraged by the difficulties you encounter in proclaiming My mercy. These difficulties that affect you so painfully are needed for your sanctification and as evidence that this work is Mine. My daughter, be diligent in writing down every sentence I tell you concerning My mercy, because this is meant for a great number of souls who will profit from it. — Diary, 1142
Today, I asked the Lord's pardon for all the offenses committed in our convents from which His divine Heart suffers. — Diary, 1144
June 20, . We resemble God most when we forgive our neighbors. God is Love, Goodness, and Mercy...
Every soul, and especially the soul of every religious, should reflect My mercy. My Heart overflows with compassion and mercy for all. The heart of My beloved must resemble Mine; from her heart must spring the fountain of My mercy for souls; otherwise I will not acknowledge her as Mine. — Diary, 1148
O Jesus, I want to live in the present moment, to live as if this were the last day of my life. I want to use every moment scrupulously for the greater glory of God, to use every circumstance for the benefit of my soul. I want to look upon everything, from the point of view that nothing happens without the will of God.
God of unfathomable mercy, embrace the whole world and pour Yourself out upon us through the merciful Heart of Jesus. — Diary, 1183
The Divine Mercy Novena (Diary, 1209-1229)
Despite the peace in my soul, I fight a continuous battle with the enemy of my soul. More and more, I am discovering his traps, and the battle flares up anew. During interludes of calm, I exercise myself and keep watch, lest the enemy find me unprepared. And when I see his great fury, I stay inside the stronghold; that is, the Most Sacred Heart of Jesus. — Diary, 1287
O humility, lovely flower, I see how few souls possess you. Is it because you are so beautiful and at the same time so difficult to attain? O yes, it is both the one and the other. Even God takes great pleasure in her. The floodgates of heaven are open to a humble soul, and a sea of graces flows down upon her. O how beautiful is a humble soul! From her heart, as from a censer, rises a varied and most pleasing fragrance which breaks through the skies and reaches God Himself, filling His Most Sacred Heart with joy. God refuses nothing to such a soul; she is all-powerful and influences the destiny of the whole world. God raises such a soul up to His very throne, and the more she humbles herself, the more God stoops down to her, pursuing her with His graces and accompanying her at every moment with His omnipotence. Such a soul is most deeply united with God. O humility, strike deep roots in my whole being. O Virgin most pure, but also most humble, help me to attain deep humility. Now I understand why there are so few saints; it is because so few souls are deeply humble. — Diary, 1306
October 10, . O my Jesus, in thanksgiving for Your many graces, I offer You my body and soul, intellect and will, and all the sentiments of my heart. Through the vows, I have given myself entirely to You; I have then nothing more that I can offer you. Jesus said to me, My daughter, you have not offered Me that which is really yours. I probed deeply into myself and found that I love God with all the faculties of my soul and, unable to see what it was that I had not yet given to the Lord, I asked, "Jesus, tell me what it is, and I will give it to you at once with a generous heart." Jesus said to me with kindness, Daughter, give Me your misery, because it is your exclusive property. At that moment, a ray of light illumined my soul, and I saw the whole abyss of my misery. In that same moment I nestled close to the Most Sacred Heart of Jesus with so much trust that even if I had the sins of all the damned weighing on my conscience, I would not have doubted God's mercy but, with a heart crushed to dust, I would have thrown myself into the abyss of Your mercy. I believe, O Jesus, that you would not reject me, but would absolve me through the hand of Your representative. — Diary, 1318
Hail, most merciful Heart of Jesus,
Living Fountain of all graces,
Our sole shelter, our only refuge;
In You I have the light of hope.
Hail, most compassionate Heart of my God,
Unfathomable living Fount of Love
From which gushes life for sinful man
And the Spring of all sweetness.
Hail, open Wound of the Most Sacred Heart,
From which the rays of mercy issued forth
And from which it was given us to draw life
With the vessel of trust alone.
Hail, God's goodness, incomprehensible,
Never to be measured or fathomed,
Full of love and mercy, though always holy,
Yet, like a good mother, ever bent o'er us.
Hail, Throne of Mercy, Lamb of God,
Who gave Your life in sacrifice for me,
Before whom my soul humbles itself daily,
Living in faith profound. — Diary, 1321
Eighth day. O my Lord, while calling to mind all Your blessings, in the presence of Your Most Sacred Heart, I have felt the need to be particularly grateful for so many graces and blessings from God. I want to plunge myself in thanksgiving before the Majesty of God and to continue in this prayer of thanksgiving for seven days and seven nights; and although I will outwardly carry out all my duties, my spirit will nonetheless stand continually before the Lord, and all my exercises will be imbued with the spirit of thanksgiving. Each evening, I will kneel for a half hour in my cell, alone with the Lord. As often as I shall awake at night, I shall steep myself in a prayer of thanksgiving. In this way, I want to repay, at least in some small way, for the immensity of God's blessings.
However, in order to make all this more pleasing in the eyes of God and to remove the least shadow of doubt from my mind, I went to my spiritual director [Father Andrasz] and revealed these desires of my soul to him; that is to say, the desire to be steeped in such thanksgiving. I received permission for everything, except that I should not force myself to pray at night should I awaken. — Diary, 1367-1368
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.
Conversation of the Merciful God with a Sinful Soul.
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.
Soul: Lord, I hear your voice calling me to turn back from the path of sin, but I have neither the strength nor the courage to do so.
Jesus: I am your strength, I will help you in the struggle.
Soul: Lord, I recognize your holiness, and I fear You.
Jesus: 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.
Soul: Lord, I doubt that You will pardon my numerous sins; my misery fills me with fright.
Jesus: 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.
Soul: You have conquered, O Lord, my stony heart with Your goodness. In trust and humility I approach the tribunal of Your mercy, where You Yourself absolve me by the hand of your representative. O Lord, I feel Your grace and Your peace filling my poor soul. I feel overwhelmed by Your mercy, O Lord. You forgive me, which is more than I dared to hope for or could imagine. Your goodness surpasses all my desires. And now, filled with gratitude for so many graces, I invite You to my heart. I wandered, like a prodigal child gone astray; but you did not cease to be my Father. Increase Your mercy toward me, for You see how weak I am.
Jesus: Child, speak no more of your misery; it is already forgotten. Listen, My child, to what I desire to tell you. Come close to My wounds and draw from the Fountain of Life whatever your heart desires. Drink copiously from the Fountain of Life and you will not weary on your journey. Look at the splendors of My mercy and do not fear the enemies of your salvation. Glorify My mercy. — Diary, 1485
Conversation of the Merciful God with a Despairing Soul.
Jesus: O soul steeped in darkness, do not despair. All is not yet lost. Come and confide in your God, who is love and mercy.
— But the soul, deaf even to this appeal, wraps itself in darkness.
Jesus calls out again: My child, listen to the voice of your merciful Father.
— In the soul arises this reply: "For me there is no mercy," and it falls into greater darkness, a despair which is a foretaste of hell and makes it unable to draw near to God.
Jesus calls to the soul a third time, but the soul remains deaf and blind, hardened and despairing. Then the mercy of God begins to exert itself, and, without any co-operation from the soul, God grants it final grace. If this too is spurned, God will leave the soul in this self-chosen disposition for eternity. This grace emerges from the merciful Heart of Jesus and gives the soul a special light by means of which the soul begins to understand God's effort, but conversion depends on its own will. The soul knows that this, for her, is final grace and, should it show even a flicker of good will, the mercy of God will accomplish the rest.
My omnipotent mercy is active here. Happy the soul that takes advantage of this grace.
Jesus: What joy fills My Heart when you return to Me. Because you are weak, I take you in My arms and carry you to the home of My Father.
Soul (as if awaking, asks fearfully): Is it possible that there yet is mercy for me?
Jesus: There is, My child. You have a special claim on My mercy. Let it act in your poor soul; let the rays of grace enter your soul; they bring with them light, warmth, and life.
Soul: But fear fills me at the thought of my sins, and this terrible fear moves me to doubt Your goodness.
Jesus: 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.
Soul: O Lord, save me Yourself, for I perish. Be my Savior. O Lord, I am unable to say anything more; my pitiful heart is torn asunder; but You, O Lord...
Jesus does not let the soul finish but, raising it from the ground, from the depths of its misery, He leads it into the recesses of His Heart where all its sins disappear instantly, consumed by the flames of love.
Jesus: Here, soul, are all the treasures of My Heart. Take everything you need from it.
Soul: O Lord, I am inundated with Your grace. I sense that a new life has entered into me and, above all, I feel Your love in my heart. That is enough for me. O Lord, I will glorify the omnipotence of Your mercy for all eternity. Encouraged by Your goodness, I will confide to You all the sorrows of my heart.
Jesus: Tell me all, My child, hide nothing from Me, because My loving Heart, the Heart of your Best Friend, is listening to you.
Soul: O Lord, now I see all my ingratitude and Your goodness. You were pursuing me with Your grace, while I was frustrating Your benevolence. I see that I deserve the depths of hell for spurning Your graces.
Jesus (interrupting): Do not be absorbed in your misery — you are still too weak to speak of it — but, rather, gaze on My Heart filled with goodness, and be imbued with My sentiments. Strive for meekness and humility; be merciful to others, as I am to you; and, when you feel your strength failing, if you come to the fountain of mercy to fortify your soul, you will not grow weary on your journey.
Soul: Now I understand Your mercy, which protects me, and like a brilliant star, leads me into the home of my Father, protecting me from the horrors of hell that I have deserved, not once, but a thousand times. O Lord, eternity will hardly suffice for me to give due praise to Your unfathomable mercy and Your compassion for me. — Diary, 1486
I remind you, My daughter, that 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 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.
My daughter, try your best to make the Stations of the Cross in this hour, provided that your duties permit it; and if you are not able to make the Stations of the Cross, then at least step into the chapel for a moment and adore, in the Blessed Sacrament, My Heart, which is full of mercy; and should you be unable to step into the chapel, immerse yourself in prayer there where you happen to be, if only for a very brief instant. I claim veneration for My mercy from every creature, but above all from you, since it is to you that I have given the most profound understanding of this mystery. — Diary, 1572
First Friday. When I took the Messenger of the Sacred Heart into my hand and read the account of the canonization of Saint Andrew Bobola, my soul was instantly filled with a great longing that our Congregation, too, might have a saint, and I wept like a child that there was no saint in our midst. And I said to the Lord, "I know your generosity, and yet it seems to me that you are less than generous toward us." And I began again to weep like a little child. And the Lord Jesus said to me, Don't cry. You are that saint. Then the light of God inundated my soul, and I was given to know how much I was to suffer, and I said to the Lord, "How will that come about? You have been speaking to me about another Congregation." And the Lord answered, It is not for you to know how this will come about. Your duty is to be faithful to My grace and to do always what is within your power and what obedience allows you to do ... — Diary, 1650
April 10, 1938. Palm Sunday. I attended Holy Mass, but did not have the strength to go and get the palm. I felt so weak that I barely made it till the end of Mass. During Mass, Jesus gave me to know the pain of His soul, and I could clearly feel how the hymns of Hosanna reverberated as a painful echo in His Sacred Heart. My soul, too, was inundated by a sea of bitterness, and each Hosanna pierced my own heart to its depths. My whole soul was drawn close to Jesus. I heard Jesus' voice: My daughter, your compassion for Me refreshes Me. By meditating on My Passion, your soul acquires a distinct beauty. — Diary, 1657
Low Sunday. Today, I again offered myself to the Lord as a holocaust for sinners. My Jesus, if the end of my life is already approaching, I beg You most humbly, accept my death in union with You as a holocaust which I offer You today, while I still have full possession of my faculties and a fully conscious will, and this for a three fold purpose:
Firstly: that the work of Your mercy may spread throughout the whole world and that the Feast of The Divine Mercy may be solemnly promulgated and celebrated.
Secondly: that sinners, especially dying sinners, may have recourse to Your mercy and experience the unspeakable effects of this mercy.
Thirdly: that all the work of Your mercy may be realized according to Your wishes, and for a certain person who is in charge of this work ...
Accept, most merciful Jesus, this, my inadequate sacrifice, which I offer to You today before heaven and earth. May Your Most Sacred Heart, so full of mercy, complete what is lacking in my offering, and offer it to Your Father for the conversion of sinners. I thirst after souls, O Christ. — Diary, 1680
May 1, . This evening, Jesus said to me, My daughter, do you need anything? I answered, "O my Love, when I have You I have everything." And the Lord answered, If souls would put themselves completely in My care, I myself would undertake the task of sanctifying them, and I would lavish even greater graces on them. There are souls who thwart My efforts, but I have not given up on them; as often as they turn to Me, I hurry to their aid, shielding them with My Mercy, and I give them the first place in My compassionate Heart. — Diary, 1682
Today, I saw the Sacred Heart of Jesus in the sky, in the midst of a great brilliance. The rays were issuing from the Wound [in His side] and spreading out over the entire world. — Diary, 1796
For more on devotion to the Sacred Heart, see Fr. Michael Gaitley, MIC's Consoling the Heart of Jesus: A Do-It-Yourself Retreat.
