In a vision, Jesus dictated the Chaplet to Saint Mary Faustina Kowalska in 1935. To pray the Chaplet, use rosary beads and begin with these prayers:
On the large (Our Father) bead of each decade, pray:
"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."
On the ten small (Hail Mary) beads of each decade, pray:
"For the sake of His sorrowful passion, have mercy on us and on the whole world."
After five decades to conclude, pray three times:
"Holy God, Holy Mighty One, Holy Immortal One, have mercy on us and on the whole world."
You may wish to add (three times):
"Jesus, I trust in You."
