On October 10, 1937, Saint
Faustina received instructions from the Lord concerning a principal element of
the devotion to the Divine Mercy: The Hour of Divine Mercy:
three o’clock, implore My mercy, especially for sinners; and, if only for a
brief moment, immerse yourself in My Passion, particularly in My abandonment at
the moment of agony. This is the hour of great mercy for the whole world. I
will allow you to enter into My mortal sorrow. In this hour, I will refuse
nothing to the soul that makes a request of me in virtue of My Passion” (Diary,
remind you, My daughter, that as often as you hear the clock strike the third
hour, immerse yourself completely in My mercy, adoring and glorifying it; invoke
its omnipotence for the whole world, and particularly for poor sinners; for at
that moment mercy was opened wide for every (145) soul. In this hour you can
obtain everything for yourself and for others for the asking; it was the hour of
grace for the whole world – mercy triumphed over justice" (Diary, 1572).
Prayers to be said at 3PM
You expired, Jesus, but the
source of life gushed forth for souls, and the ocean of mercy opened up for the
whole world. O Fount of Life, unfathomable Divine Mercy, envelop the whole
world and empty Yourself out upon us. (Diary, 1319).
O Blood and Water, which
gushed forth from the Heart of Jesus as a fount of mercy for us, I trust in You!
