I desire mercy, not sacrifice.
I did not come to call the righteous but sinners.

Matt. 9, 13

The words of Jesus to St. Sister Faustina

(Selected parts of the Diary of St. Faustina Kowalska)

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 neighbors 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 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. 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 reminded of the demands of My mercy, because even the strongest faith is of no avail without works (Diary 742)

Write this for the many souls who are often worried because they do not have the material means with which to carry out an act of mercy. Yet spiritual mercy, which requires neither permission nor storehouses, is much more meritorious and is within the grasp of every soul. If a soul does not exercise mercy somehow or other, it will not obtain My mercy on the day of judgment. Oh, if only souls knew how to gather eternal treasure for themselves, they would not be judged, for they would forestall My judgment with their mercy (Diary 1317)
