The DIARY of Sister Faustina, written in the form of a journal, records the last four years of her life. It reveals the depths of her spiritual life and illustrates the high degree of her soul’s union with God. The Lord endowed Sister Faustina with tremendous graces: the gift of contemplation, a deep knowledge of the mystery of the mercy of God, visions, revelations, the hidden stigmata, the gifts of prophecy and of reading human souls, and also the rare gift of mystical espousal (Diary Introduction, p. 10, Polish Edition).

“Secretary of My most profound mystery, know that yours is an exclusive intimacy with Me. Your task is to write down everything that I make known to you about My mercy, for the benefit of those who by reading these things will be comforted in their souls and will have the courage to approach Me. I therefore want you to devote all your free moments to writing” (Diary, 1693).


“My Heart overflows with great mercy for souls (...). 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 fountain overflowing with mercy. For them I dwell in the tabernacle as the King of Mercy. I desire to bestow My graces upon souls, but they do not want to accept them (...). Oh, how indifferent are souls to so much goodness, to so many proofs of love! (...). They have time for everything, but they have no time to come to Me for graces” (Diary, 367).


“Tell sinners that no one shall escape My Hand; if they run away from My Merciful Heart, they will fall into My Just Hands. Tell sinners that I am always waiting for them, that I listen intently to the beating of their heart... When will it beat for Me? Write that I am speaking to them through their remorse of conscience, through their failures and sufferings, through thunderstorms, through the voice of the Church. And if they bring all My graces to naught, I begin to be angry with them, leaving them alone and giving them what they want” (Diary, 1728).





“God never violates our free will. It is up to us whether we want to receive God’s grace or not. It is up to us whether we will co-operate with it or waste it” (Diary, 1107).


“...I saw two roads. One was broad, covered with sand and flowers, full of joy, music and all sorts of pleasures. People were walking along it, dancing and enjoying themselves. They reached the end without realizing it. And at the end of the road there was a horrible precipice; that is, the abyss of hell. The souls fell blindly into it; as they walked, so they fell. And their number was so great that it was impossible to count them. And I saw the other road, or rather, a path, for it was narrow and strewn with thorns and rocks; and the people who walked along it had tears in their eyes, and all kinds of suffering befell them. Some fell down upon the rocks, but stood up immediately and went on. At the end of the road there was a magnificent garden filled with all sorts of happiness and all these souls entered there. At the very first instant they forgot all their sufferings” (Diary, 153).


“...How fleeting all earthly things are. Everything that appears great disappears like smoke and does not give the soul freedom, but weariness. Happy the soul that understands these things and with only one foot touches the earth” (Diary, 1141).


“...If a soul loves God sincerely and is intimately united with Him, then, even though such a soul may be living in the midst of difficult external circumstances, nothing can disturb its interior life. In the midst of corruption, it can remain pure and unsullied because the great love of God gives it strength for battle, and God also protects it in a special way” (Diary, 1094).


“The Lord gave me much light to know His attributes. The first attribute that the Lord revealed to me is to know is His holiness. His holiness is so great that all the Powers and Virtues tremble before Him(...). The holiness of God is poured out upon the Church of God and upon every living soul, but not in the same degree. There are souls who are completely penetrated by God, and there are those who are barely alive. The second form of knowledge that the Lord granted me concerns His justice. His justice is so great and penetrating that it reaches deep into the heart of things, and all things stand before Him in naked truth (...).
The third attribute He revealed is His love and mercy. And I understood that this is the greatest attribute. It unites the creature with the Creator. This immense love and abyss of mercy are made known in the Incarnation of the Word and in the Redemption [of humanity], and it is here that I saw this as the greatest of all God’s attributes” (Diary, 180).


“All that is great and beautiful is in God (...). O you sages of the world and you great minds, recognize that true greatness is in loving God!” (Diary, 990).


“Jesus, You have allowed me to know and understand in what a soul’s greatness consists: not in great deeds but in great love. Love has its worth, and it confers greatness on all our deeds. Although our actions are small and ordinary in themselves, because of love they become great and powerful before God” (Diary, 889).


“True greatness of the soul is in loving God and in humility” (Diary, 427).


“As the soul continues to immerse itself more deeply into the abyss of its nothingness and need, God uses His omnipotence to exalt it. If there is a truly happy soul upon earth, it can only be a truly humble soul. At first, one’s self-love suffers greatly on this account, but after a soul has struggled courageously, God grants it much light by which it sees how wretched and full of deception everything is” (Diary, 593).


“The floodgates of heaven are open to a humble soul, and a sea of graces flows down upon it (...). God refuses nothing to such a soul; it is all-powerful and influences the destiny of the whole world. God raises up such a soul to His very throne, and the more the soul humbles itself, the more God stoops down to it, pursuing it with His graces and accompanying it at every moment with His omnipotence” (Diary, 1306).


“God, who is Light, lives in a pure and humble heart, and all sufferings and adversities serve but to reveal the soul’s holiness” (Diary, 573).


“...Humility is nothing but the truth. There is no cringing in true humility. Although I consider myself the least (...). I enjoy the honour of being the beloved of Christ” (Diary, 1502).


“O my Jesus, You know what efforts are needed to live sincerely and unaffectedly with those from whom our nature flees, or with those who, deliberately or not, have made us suffer. In human terms alone, this is impossible. At such times more than at others, I try to discover the Lord Jesus in such a person and for this same Jesus, I do everything for such people. In such acts, love is pure, and such practice of love gives the soul endurance and strength. I do not expect anything from creatures, and therefore I am not disappointed...” (Diary, 766).


“Jesus, my most perfect model, with my eyes fixed on You, I will go through life in Your footsteps, adapting nature to grace, according to Your most holy will and Your light which illuminates my soul, trusting completely in Your help” (Diary, 1351).
