The Words of God
from Saint Faustina's Diary regarding Divine Mercy Sunday

"...tell the whole world about about My inconceivable mercy. I desire that the Feast of Mercy be a refuge and shelter for all souls, especially for poor sinners. On that day the very depths of My tender mercy are open."

"I pour out a whole ocean of graces upon those souls who approach the Fount of My Mercy. The soul that will go to Confession and receive Holy Communion shall obtain complete forgiveness of sins and punishment. On that day all
the divine floodgates through which graces flow are opened. Let no soul fear to draw near Me, even though its sins be as scarlet. My mercy is so great that no mind, be it of man or angel, will be able to fathom it throughout all eternity. The Feast of Mercy emerged from My very depths of tenderness.

It is My desire that it be solemnly celebrated on the first Sunday after Easter. Mankind will not have peace until it turns to the Fount of My mercy." (699)

"Every soul believing and trusting in My mercy will obtain it." (420)

"I am giving you three ways of exercising mercy toward your neighbor: 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. . the Feast of Mercy . is to be a reminder of the demands of My mercy, because even the strongest faith is of no avail without works."
