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 the sins of the whole world...for the sake of His sorrowful Passion have mercy on us and on the whole world...O God! Holy Mighty God! Holy Immortal One, have mercy on us and on the whole world. Amen.
As you pray focus on how merciful Jesus is, how His love is so great that no matter how great or many your sins are, all He wishes is to forgive you and shower you with His Divine mercy. The message at the bottom of the painting is the original Polish meaning "Jesus I trust in You."
There is a beautiful version of this set to music. Contact me and I will send a CD copy of it to you. For more on-line information look up St Faustina and The Divine Mercy.
