In 1935, Jesus requested St. Faustina to encourage everyone to pray "The Chaplet of Mercy." Jesus said "Encourage souls to say the Chaplet...Whoever will recite it will receive great mercy...Through the Chaplet you will obtain everything, if what you ask is compatible with My will."
Using a rosary begin with:
Our Father, Hail Mary, Apostles' Creed
On large bead before 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 10 small beads of each decade pray:
"For the sake of His sorrowful Passion, have mercy on us and on the whole world."
Conclude by praying 3 times:
Holy God, Holy Mighty One, Holy Immortal One, have mercy on us and on the whole world."
