“Paint the 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 throughout the world.” (Diary, 47)
“I promise that the soul that shall venerate this image will not perish.” (Diary, 48)
“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)”
“Jesus looked at me and said, Souls perish in spite of My bitter Passion. I am giving them the last hope of salvation; that is the Feast of My Mercy. If they will not adore My mercy, they will perish for all eternity.” (Diary, 965)
“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)
“I desire that the image be publicly honored.” (Diary, 414)
“By means of this image, I shall be granting many graces to souls; so let every soul have access to it.” (Diary, 570)
To obtain this forgiveness we must go to the Holy Sacrifice of the Mass and receive Holy Communion on Divine Mercy Sunday which is the Sunday after Easter Sunday. In addition, we must go to Confession and receive absolution within 20 days before or after Divine Mercy Sunday.
We expect that during the Mass, the priest will invite us to venerate the divine mercy image at the top of this page. If he does not, we must venerate the image on our own. We must also perform spiritual and corporal acts of mercy.
The Plenary Indulgence for Divine Mercy Sunday provides the details. In particular,
“The plenary indulgence is granted (under the usual conditions of a sacramental confession, Eucharistic communion and a prayer for the intentions of the Supreme Pontiff) to the faithful who, on Divine Mercy Sunday, in a spirit that is completely detached from the affection for a sin, even a venial sin, recite the Our Father and the Creed, and also adding a devout prayer (e.g. Merciful Jesus, I trust in you!).”
Remember also these words of Rabbi Yeshua: “I desire that the Feast of Mercy be a refuge and shelter for all souls, and especially poor sinners. On that day the very depths of My tender mercy are open. The soul that will go to Confession and receive Holy Communion shall obtain complete forgiveness of sins and punishment.” (699) “Souls perish in spite of My bitter Passion. I am giving them the last hope of salvation; that is, the Feast of My Mercy. If they will not adore My mercy, they will perish for all eternity…tell souls about this great mercy of Mine, because the awful day, the day of My justice, is near. (965).
Rabbi Yeshua told St. Faustina, “When you approach the confessional, know this, that I Myself am waiting there for you. I am only hidden by the priest, but I Myself act in your soul. Here the misery of the soul meets the God of mercy. Tell souls that from this fount of mercy souls draw graces solely with the vessel of trust. If their trust is great, there is no limit to My generosity.” (1602)
And pray it every day.
