Our Lord 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).
As often as you hear the clock strike the third hour immerse yourself completely in My mercy, adoring and glorifying it, invoke it's 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.
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)
THE THREE O'CLOCK PRAYER
You died Jesus, but the source of life flowed out for souls and the ocean of mercy opened up for the whole world.
O Fountain of Life, immeasurable Divine Mercy, cover the whole world and empty Yourself out upon us.
O Blood and Water which flowed out from the heart of Jesus as a Fountain of Mercy for us, I trust in You!
Holy God, Holy Mighty One, Holy Immortal One, have mercy on us and the whole world.
Holy God, Holy Mighty One, Holy Immortal One, have mercy on us and the whole world.
Holy God, Holy Mighty One, Holy Immortal One, have mercy on us and the whole world.
AMEN.
Jesus, King of Mercy, we trust in You!
PRAYER BEFORE A CRUCIFIX
BEHOLD, O good and sweetest Jesus, I cast myself upon my knees in Thy sight, and with the most fervent de sire of my soul I pray and beseech Thee to impress upon my heart lively sentiments of faith, hope and charity, with true repentance for my sins and a most firm desire of amendment: whilst with deep affection and grief of soul I consider within myself and mentally contemplate Thy five most precious Wounds, having before mine eyes that which David, the prophet, long ago spoke in Thine own person concerning Thee, my Jesus: They have pierced my hands and my feet, they have numbered all my bones [Psalm 21, 17, 18].
Say Our Father, Hail Mary, Glory Be for the Catholic Church and the intentions of the Holy Father. A plenary indulgence, under the usual conditions, may be gained by those who shall say this prayer with devotion before an image of our crucified Redeemer. An partial indulgence may also be gained for each devout recitation.
PRAYER TO THE SORROWFUL MOTHER
Most holy Mother of Sorrows, by that soul-piercing martyrdom thou didst undergo at the foot of the Cross during the three hours' agony of Jesus, deign to assist me also, who am the child of thy Sorrows, in my agony, so that by thine intercession I may be found worthy to pass from my deathbed to thy blessed society in Paradise.
V. From a sudden and unprovided death,
R. Deliver me, O Lord.
V. From the snares of the devil,
R. Deliver me, O Lord.
V. From everlasting death,
R. Deliver me, O Lord.
Let us pray.
O God, Who for the salvation of mankind hast made for us in the most bitter death of Thy Son both an example and a refuge; grant, we beseech Thee, that we may be found worthy to obtain the fruit of His great love in our final peril at the hour of death, and to be made partakers of our Redeemer's glory. Through the same Christ our Lord. Amen.
