In the Diary of Saint Maria Faustina, Jesus revealed to Saint Faustina a nine day novena that He desired to be prayed in preparation for Divine Mercy Sunday. He asked that each day's prayers be dedicated to a different grouping of people. This nine day novena begins today, April 15th, and is prayed each day until April 23rd. To help aid anyone that wishes to participate in the novena this year, below is a free online guide that will walk you through each day's prayers.
"I am love and Mercy Itself. There is no misery that could be a match for My mercy, neither will misery exhaust it, because as it is being granted – it increases. The soul that trusts in My mercy is most fortunate, because I Myself take care of it."
-Words of Jesus to St. Faustina
