This message and devotion to Jesus as The Divine Mercy is based on the writings of Saint Faustina Kowalska, an uneducated Polish nun who, in obedience to her spiritual director, wrote a diary of about 600 pages recording the revelations she received about God's mercy. Even before her death in 1938, the devotion to The Divine Mercy had begun to spread. The message and devotional practices proposed in the Diary of Saint Faustina are completely in accordance with the teachings of Church and are firmly rooted in the Gospel message of our Merciful Savior. Properly understood and implemented, they will help us grow as genuine followers of Christ.
The message of The Divine Mercy is simple. It is that God loves us – all of us. And, he wants us to recognize that His mercy is greater than our sins, so that we will call upon Him with trust, receive His mercy, and let it flow through us to others. Thus, all will come to share His joy. The Divine Mercy message is one we can call to mind simply by remembering ABC:
A - Ask for His Mercy. God wants us to approach Him in prayer constantly, repenting of our sins and asking Him to pour His mercy out upon us and upon the whole world.
B - Be merciful. God wants us to receive His mercy and let it flow through us to others. He wants us to extend love and forgiveness to others just as He does to us.
C - Completely trust in Jesus. God wants us to know that the graces of His mercy are dependent upon our trust. The more we trust in Jesus, the more we will receive.
Pope John Paul II, both in his teaching and personal life, strove to live and teach the message of Divine Mercy. He wrote an encyclical on Divine Mercy: "The Message of Divine Mercy has always been near and dear to me… which I took with me to the See of Peter and which it in a sense forms the image of this Pontificate."
In his writings and homilies, he has described Divine Mercy as the answer to the world’s problems and the message of the third millennium. He beatified and canonized Sr. Maria Faustina Kowalska, the nun associated with the message, in Rome - not in Poland to underscore that Divine Mercy is for the whole world.
When Pope John Paul II canonized Sr. Faustina, he also established Divine Mercy Sunday as a liturgical feast day for the universal Church. The feast day falls on the Second Sunday of the Easter season.
