February 22, 1931 – 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. (Diary 47)
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. (Diary 48)
When I told this to my confessor, I received this for a reply: “That refers to your soul.” He told me, “Certainly, paint God’s image in your soul.” When I came out of the confessional, I again heard words such as these:  My image already is in your soul. I desire that there be a Feast of Mercy. I want this image, which you will paint with a brush, to be solemnly blessed on the first Sunday after Easter; that Sunday is to be the Feast of Mercy. (Diary 49)
During adoration, I felt God close to me. A moment later I saw Jesus and Mary. At the sight of them I was filled with joy, and I asked the Lord, “What is Your will, Jesus, concerning the matter about which my confessor told me to ask You?” Jesus replied,  It is My Will that he should remain here and that he should not take the initiative of dispensing himself.  I asked Jesus whether the inscription could be: “Christ King of Mercy.” He answered,  I am King of Mercy , but He did not say “Christ.”  I desire that this image be displayed in public on the first Sunday after Easter. That Sunday is the Feast of Mercy. Through the Word Incarnate I make known the bottomless depth of My mercy. (Diary 88)
When, on one occasion, my confessor told me to ask the Lord Jesus the meaning of the two rays in the Image, I answered, “Very well, I will ask the Lord”. During prayer I heard these words within me:  The two rays denote Blood and Water. The pale ray stands for the Water which makes souls righteous. The red ray stands for the Blood which is the life of souls… These two rays issued forth from the very depths of My tender mercy when My agonized Heart was opened by a lance on the Cross. These rays shield souls from the wrath of My Father. Happy is the one who will dwell in their shelter, for the just hand of God shall not lay hold of him. I desire that the first Sunday after Easter be the Feast of Mercy. (Diary 299)
Once, Jesus said to me,  My gaze from this Image is like My gaze from the cross. (Diary 326)
Once, my confessor [Father Sopocko] asked me where the inscription should be placed, because there was not enough space in the picture for everything. I answered, “I will pray and give you an answer next week.” When I left the confessional and was passing before the Blessed Sacrament, I received an inner understanding about the inscription. Jesus reminded me of what He had told me the first time; namely, that these three words must be clearly in evidence: “Jesus, I trust in You.” [“Jezu, Ufam Tobie.”] I understood that Jesus wanted the whole formula to be there, but He gave no direct orders to this effect as He did for these three words. I am offering people a vessel with which they are to keep coming for graces to the fountain of mercy. That vessel is this Image with the signature: “Jesus, I trust in You.” (Diary 327)
Once, the Image was being exhibited over the altar during the Corpus Christi procession [June 20, 1935]. When the priest exposed the Blessed Sacrament, and the choir began to sing, the rays from the Image pierced the Sacred Host and spread out all over the world. Then I heard these words:  These rays of mercy will pass through you, just as they have passed through this Host, and they will go out through all the world.  At these words, profound joy invaded my soul.(Diary 441)
Good Friday. At three o’clock, I saw the Lord Jesus, crucified, who looked at me and said,  I thirst.  Then I saw two rays issue from His side, just as they appear in the Image. I then felt in my soul the desire to save souls and to empty myself for the sake of poor sinners. I offered myself, together with the dying Jesus, to the Eternal Father, for the salvation of the whole world. With Jesus, through Jesus and in Jesus is my communion with You, Eternal Father. On Good Friday, Jesus suffered in His soul in a way which was different from His suffering on Holy Thursday.(Diary 648)
My daughter, if I demand through you that people revere My mercy, you should be the first to distinguish yourself by this confidence in My mercy. I demand from you deeds of mercy, which are to arise out of love for Me. You are to show mercy to your neighbours always and everywhere. You must not shrink from this or try to excuse or absolve yourself from it.I am giving you three ways of exercising mercy toward your neighbour: the first — by deed, the second — by word, the third— by prayer. In these three degrees is contained the fullness of mercy, and it is an unquestionable proof of love for Me. By this means a soul glorifies and pays reverence to My mercy. Yes, the first Sunday after Easter is the Feast of Mercy, but there must also be acts of mercy, and I demand the worship of My mercy through the solemn celebration of the Feast and through the veneration of the Image which is painted. By means of this Image I shall grant many graces to souls. It is to be a reminder of the demands of My mercy, because even the strongest faith is of no avail without works.  O my Jesus, You yourself must help me in everything, because You see how very little I am, and so I depend solely on Your goodness, O God.(Diary 742)
November 10, 1937 – When Mother [Irene] showed me the booklet with the Chaplet, the Litany and the Novena, I asked her to let me look it over. As I was glancing through it, Jesus gave me to know interiorly:  Already there are many souls who have been drawn to My love by this Image. My mercy acts in souls through this work.  I learned that many souls had experienced God’s grace.(Diary 1379)
