“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.”

Diary, para.441

There is no getting away from the fact that if we are devoted to the message of Divine Mercy, then we are called to be not only witnesses of mercy, but vessels of mercy; in other words, the Merciful Lord wishes to make use of us daily in practical ways in order to make His mercy flow out through all the world. 

In the Diary of Saint Faustina (cf. para.742), He tells us how to be merciful – 

St Faustina Kowalska

“I demand from you deeds of mercy, which are to arise out of love for Me. You are to show mercy always and everywhere. You mist 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.”

In the same way that sunlight passes through a window, illuminating and warming what is beyond, so must the mercy of the Lord flow through us. The window does not create that sunlight, it simply allows itself to be a vessel, that the light might pass through it; so must it be with us. 

Every day, let us waste no opportunity to exercise mercy in one of these three ways given to us by the Lord – by deed, by word and by prayer. In these three forms, the exercise of mercy is possible for every person, regardless of their situation.

Let us waste no time – the world greatly needs that Divine Mercy.
