"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."
— Jesus to St. Faustina (Diary, 1320)
Jesus gave the Divine Mercy Chaplet to St. Maria Faustina Kowalska (1905-1938), a Polish religious sister, during a series of revelations in the 1930s. He asked that it be prayed especially at 3:00 PM, the Hour of Mercy, to commemorate the hour of His death.
The chaplet is prayed on ordinary rosary beads and takes about 10-15 minutes. Jesus made extraordinary promises to those who pray it: "Whoever will recite it will receive great mercy at the hour of death... Even if there were a sinner most hardened, if he were to recite this chaplet only once, he would receive grace from My infinite mercy."
Using ordinary rosary beads
On the crucifix, make the Sign of the Cross and pray:
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 3 times:)
O Blood and Water, which gushed forth from the Heart of Jesus as a fountain of Mercy for us, I trust in You!
On the first three beads
Pray once at the start of each decade
Eternal Father, I offer You the Body and Blood, Soul and Divinity of Your dearly beloved Son, Our Lord Jesus Christ, in atonement for our sins and those of the whole world.
Pray 10 times on each decade
For the sake of His sorrowful Passion, have mercy on us and on the whole world.
After 5 decades, conclude with:
(Repeat 3 times:)
Holy God, Holy Mighty One, Holy Immortal One, have mercy on us and on the whole world.
Eternal God, in whom mercy is endless and the treasury of compassion inexhaustible, look kindly upon us and increase Your mercy in us, that in difficult moments we might not despair nor become despondent, but with great confidence submit ourselves to Your holy will, which is Love and Mercy itself. Amen.
"The souls that say this chaplet will be embraced by My mercy during their lifetime and especially at the hour of their death."
"When they say this chaplet in the presence of the dying, I will stand between My Father and the dying person, not as the just Judge but as the merciful Savior."
"Priests will recommend it to sinners as their last hope of salvation. Even if there were a sinner most hardened, if he were to recite this chaplet only once, he would receive grace from My infinite mercy."
