From the Diary of St. Faustina
1572-I 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 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.
My daughter, try your best to make the Stations of the Cross in this hour, provided that your duties permit it, and if you are not able to make the Stations of the Cross, then at least step into the chapel for a moment and adore, in the Blessed Sacrament, My Heart, which is full of mercy; and should you be unable to go into the chapel, immerse yourself in prayer there where you happen to be, if only for a very brief instant. I claim veneration for My mercy from every creature, but above all from you, since it is to you that I have given the most profound understanding of this mystery. +JMJ+
