Saint Faustina was born Helena Kowalska in the village of Glogowiec west of Lodz, Poland, on August 25, 1905. She was the third of ten children. When she was almost twenty, she entered the Congregation of the Sisters of Our Lady of Mercy, whose members devote themselves to the care and education of troubled young women.
The following year she received her religious habit and was given the name Sister Maria Faustina, to which she added "of the Most Blessed Sacrament," as was permitted by her Congregation's custom.
In the 1930s, Sister Faustina received from the Lord a message of mercy that she was told to spread throughout the world. She was asked to become the apostle and secretary of God's mercy, a model of how to be merciful to others, and an instrument for reemphasizing God's plan of mercy for the world.
The message of mercy that Sister Faustina received is now being spread throughout the world; she has been recognized by the Church as a "Saint"; and her diary, Divine Mercy in My Soul, has become the handbook for devotion to The Divine Mercy. She would not have been surprised, for she had been told that the message of God's mercy would spread through her writings for the great benefit of souls.
Through Saint Faustina, Jesus also revealed special ways to live out the response to His mercy–one of which is the Chaplet of Divine Mercy, as both a novena and a prayer for the three o'clock hour–the hour of His death.
WHAT IS THE DIVINE MERCY MESSAGE AND DEVOTION?
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.
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.
