Known as the second most important book in the world after the Bible, St Faustina's Diary has allowed us intimate glimpses of the very heart of Jesus who wanted very much to bestow his mercy to us all but sadly, many of us are simply not aware or not interested.
From age 7, St Faustina started to have deep experiences of God and Jesus appeared to her often till her death at age 33. Her diary captures her conversations with Jesus who yearned for souls to turn to His Mercy for salvation.
You can freely download the PDF of her diary here.
In my pilgrimage to Western Europe in 2018, I had the privilege of visiting the Divine Mercy Shrine at Krakow and I had such a powerful experience there that I immediately bought St Faustina's Diary to learn more about Divine Mercy!
Here're some of my favourite entries of her diary which would give you a good idea of its power to transform our lives:
47 In the evening, when I was in my cell, I saw the Lord Jesus clothed in a white garment. One hand was raised in the gesture of blessing, the other was touching the garment at the breast. From beneath the garment, slightly drawn aside at the breast, there were emanating two large rays, one red, the other pale. In silence I kept my gaze fixed on the Lord; my soul was struck with awe, but also with great joy. After a while, Jesus said to me, Paint an image according to the pattern you see, with the signature: Jesus, I trust in You. I desire that this image be venerated, first in your chapel, and then throughout the world.
48 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.
50 I desire that priests proclaim this great mercy of Mine towards souls of sinners. Let the sinner not be afraid to approach Me. The flames of mercy are burning Me –clamoring to be spent; I want to pour them out upon these souls.
279 God made known to me what true love consists in and gave light to me about how, in practice, to give proof of it to Him. True love of God consists in carrying out God's will. To show God our love in what we do, all our actions, even the least, must spring from our love of God. And the Lord said to me, My child, you please me most by suffering. In your physical as well as your mental sufferings, my daughter, do not seek sympathy from creatures. I want the fragrance of your suffering to be pure and unadulterated. I want you to detach yourself, not only from creatures, but also from yourself. My daughter, I want to delight in the love of your heart, a pure love, virginal, unblemished, untarnished. The more you will come to love suffering, My daughter, the purer your love for Me will be.
1446 The Lord said to me, It should be of no concern to you how anyone else acts; you are to be My living reflection, through love and mercy. I answered, “Lord, but they often take advantage of my goodness.” That makes no difference, My daughter. That is no concern of yours. As for you, be always merciful toward other people, and especially toward sinners.
1447 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 (60) 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.
1448 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.

"Should you not have had mercy on your fellow slave, as I had mercy on you?" Matthew 18:33
