Somewhat lost in the Easter shuffle is the Divine Mercy devotion. From the Faustina.org website:
In the early 1900’s, Our Lord gave many great mystical graces to Sister Faustina of the Sisters of Our Lady of Mercy in Poland. He also gave her a mission - to tell the world that He is Mercy itself, and that before He returns as a just Judge, He is coming as a merciful Savior. Jesus called Faustina His “Secretary of Divine Mercy”, and commanded her to write everything He told her. In obedience, Faustina kept a diary, now called "Divine Mercy in My Soul", and published by the Marians Fathers of the Immaculate Conception of Stockbridge, Massachusetts. This printed diary fills over 600 pages. Over 7 times He told her that this message would prepare the world for His final coming.
Pope John Paul II was a great believer in the Divine Mercy Devotion. The Chaplet of the Divine Mercy can be prayed at any time. The prayers of the chaplet are counted on a Rosary. The Novena to the Divine Mercy began on Good Friday and will conclude this Sunday on Divine Mercy Sunday. Instructions for praying the chaplet and the novena are here.
What is beautiful about the novena is it brings a different group of souls to Jesus each day. Since Good Friday we have presented the souls of all sinners, of priests and religious, and of the devout and faithful Christians to Jesus in our prayers. Please join today as we bring the souls of those who do not believe in God to The Divine Mercy of Jesus.
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.
For the Sake of His sorrowful Passion, have mercy on us and on the whole world.
