The moment of three o'clock in the afternoon
A devotion most dear to Our Lord is the veneration of His Passion at the very hour that recalls His death on the Cross. Through the passion and death of Jesus Christ, the very kingdom of God was opened up to us. Love should fill our response to the request of Jesus who said to Saint Faustina:
“At 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. ... In this hour I will refuse nothing to the soul that makes a request of Me in virtue of My Passion (Diary, 1320).
I remind you, my daughter, 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 Most Blessed Sacrament, My Heart, which is full of mercy; and should you be unable to step into chapel, immerse yourself in prayer there where you happen to be, if only for a very brief instant (Diary 1572).
Jesus gave this prayer, to be said at 3 o'clock especially for sinners; it is a powerful conversion prayer and should be used for those who have strayed from the faith. This is the prayer:
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.
(Repeat three times)
O Blood and Water, which gushed forth from the Heart of Jesus as a fount of mercy for us, I trust in You!
The Divine Mercy Novena begins on Good Friday and concludes with the Feast of Divine Mercy on the Sunday after Easter Sunday - the 11th April.
Jesus gave St. Faustina an intention to pray for on each day of the Novena, saving for the last day the most difficult intention of all, the lukewarm and indifferent.
