Sister Faustina was a young, uneducated nun in a convent of the Congregation of Sisters of Our Lady of Mercy in Poland during the 1930s.
She came from a poor family that struggled during the years of World War I. She had only three years of simple education, so hers were the humblest tasks in the convent, usually in the kitchen or garden. However, she received extraordinary revelations — or messages — from our Lord Jesus. Jesus asked Sr. Faustina to record these experiences, which she compiled into notebooks. These notebooks are known today as the Diary of Saint Maria Faustina Kowalska, and the words contained within are God's loving message of Divine Mercy.
Though the Divine Mercy message is not new to the teachings of the Church, Sr. Faustina's Diary sparked a great movement and a strong and significant focus on the mercy of Christ. Saint John Paul II canonized Sr. Faustina in 2000 making her the "first saint of the new millennium." Speaking of Sr. Faustina and the importance of the message contained in her Diary, the Pope called her "the great apostle of Divine Mercy in our time."

VILNIUS, Lithuania “September 13, 1935. In the evening, when I was in my cell, I saw an Angel, the executor of divine wrath. He was clothed in a dazzling robe, his face gloriously bright, a cloud beneath his feet. From the cloud, bolts of thunder and flashes of lightning were springing into his hands; and from his hand, they were going forth, and only then were they striking the earth. When I saw this sign of divine wrath which was about to strike the earth, and in particular a certain place, which for good reasons I cannot name, I began to implore the Angel to hold off for a few moments, and the world would do penance. But my plea was a mere nothing in the face of the divine anger.
(…) At that very moment, I felt in my soul the power of Jesus’ grace, which dwells in my soul. When I became conscious of this grace, I was instantly brought before the Throne of God.
(…) I found myself pleading with God for the world with words heard internally.
As I was praying in this manner, I saw the Angel’s helplessness: he could not carry out the just punishment which was rightly due for sins. Never before had I prayed with such inner power as I did then. The words with which I entreated God are these: Eternal Father, I offer You the Body and Blood, Soul and Divinity of Your dearly beloved Son, Our Lord Jesus Christ for our sins and those of the whole world; for the sake of His sorrowful Passion, have mercy on us.
The next morning, when I entered chapel, I heard these words internally: Every time you enter the chapel, immediately recite the prayer which I taught you yesterday.
When I had said the prayer, in my soul I heard these words: 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, one HAIL MARY and the I BELIEVE IN GOD. Then on the OUR FATHER beads you will say the following words: 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: 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: Holy God, Holy Mighty One, Holy Immortal One, have mercy on us and on the whole world” (Diary, 474-476).
“Oh, what great graces I will grant to souls who say this chaplet (…) Write down these words, My daughter. Speak to the world about My mercy; let all mankind recognize My unfathomable mercy. It is a sign for the end times; after it will come the day of justice. While there is still time, let them have recourse to the fountain of My mercy; let them profit from the Blood and Water which gushed forth for them” (Diary, 848).
The Promises of Grace and Mercy for the Dying
“It pleases Me to grant everything souls ask of Me by saying the chaplet. When hardened sinners say it, I will fill their souls with peace, and the hour of their death will be a happy one. Write this for the benefit of distressed souls; when a soul sees and realizes the gravity of its sins, when the whole abyss of the misery into which it immersed itself is displayed before its eyes, let it not despair, but with trust let it throw itself into the arms of My mercy, as a child into the arms of its beloved mother (…). Tell them no soul that has called upon My mercy has been disappointed or brought to shame. I delight particularly in a soul that has placed its trust in My goodness. Write that when they say this chaplet in the presence of the dying, I will stand between My Father and the dying person, not as the just Judge but as the merciful Saviour” (Diary, 1541).
“I desire that this mercy will flow out upon the whole world through your heart. Let no one who approaches you go away without that trust in My mercy, which I so ardently desire for souls. Pray as much as you can for the dying. By your entreaties, obtain for them trust in My mercy, because they have most need of trust, and have it the least”(Diary, 1777).
“My daughter, help Me to save a certain dying sinner. Say the chaplet that I have taught you for him. When I began to say the chaplet, I saw the man dying in the midst of terrible torment and struggle. His Guardian Angel was defending him, but he was, as it were, powerless against the enormity of the soul’s misery (…). But while I was saying the chaplet, I saw Jesus just as He is depicted in the image. The rays that issued from Jesus’ Heart enveloped the sick man, and the powers of darkness fled in panic. The sick man peacefully breathed his last” (Diary, 1565).
“In the presence of the dying, they ask me for prayer, and I can pray, as the Lord grants me an extraordinary spirit of prayer. I am constantly united with Him, and I am fully aware that I live for souls in order to bring them to Your mercy, O Lord. In this matter, no sacrifice is too insignificant” (Diary, 971).
“I often communicate with people who are dying and obtain Divine Mercy for them. Oh, how great is the goodness of God, greater than we can understand. There are moments and there are mysteries of the Divine Mercy over which the heavens are astounded. Let our judgment of souls cease, for God’s mercy is extraordinary” (Diary, 1684).
“God’s mercy sometimes touches the sinner at the last moment in a wondrous and mysterious way. Outwardly, it seems as if everything were lost, but it is not so. The soul, illuminated by a ray of God’s powerful final grace, turns to God in the last moment with such a power of love that, in an instant, it receives from God absolution of sins and remission of punishment, while outwardly it shows no sign either of repentance or of contrition, because souls [at that stage] no longer react to external things. Oh, how beyond comprehension is God’s mercy! But – horror! There are also souls who voluntarily and consciously reject and scorn this grace! Although a person is at the point of death, the merciful God gives the soul that interior vivid moment, so that if the soul is willing, it has the possibility of returning to God. But sometimes, the obduracy in souls is so great that consciously they choose hell; they [thus] make useless all the prayers that other souls offer to God for them and even the efforts of God Himself…” (Diary, 1698).
“O life so dull and monotonous, how many treasures you contain! When I look at everything with the eyes of faith, no two hours are alike, and the dullness and monotony disappear. The grace which is given me in this hour will not be repeated in the next. It may be given me again, but it will not be the same grace. Time goes on, never to return again. Whatever is enclosed in it will never change; it seals with a seal for eternity” (Diary, 62).
“…The Lord let me know how much He desires a soul to distinguish itself be deeds of love. And in spirit I saw how many souls are calling out to us, “Give us God.” And the blood of the Apostles boiled up within me. I will not be parsimonious with it; I will shed it all to the last drop for immortal souls. Although perhaps God will not demand that in the physical sense, in spirit it is possible and no less meritorious” (Diary, 1249).
“I desire to go throughout the whole world and to speak to souls about the great mercy of God. PRIESTS, HELP ME IN THIS…” (Diary, 491).
“Tell My priests that hardened sinners will repent on hearing their words when they speak about My unfathomable mercy, about the compassion I have for them in My Heart. To priests who proclaim and extol My mercy, I will give wondrous power; I will anoint their words and touch the hearts of those to whom they speak” (Diary, 1521).
“My daughter, look into the abyss of My mercy and give praise and glory to this mercy of Mine. Do it in this way: Gather all sinners from the entire world and immerse them in the abyss of My mercy” (Diary, 206).
“Penetrate My mysteries, and you will know the abyss of My mercy towards creatures and My unfathomable goodness. This you shall make known to the world. Through your prayers, you shall mediate between heaven and earth” (Diary, 438).
