The urgent call to proclaim The Divine Mercy comes as a plea to the Church through the mystic and prophet, St. Maria Faustina Kowalska, who died in Poland in 1938 at the age of 33. She was canonized a saint on April 30, 2000. At the age of 20, Maria Faustina Kowalska was at a dance. In her own words she describes what happened:

Once I was at a dance (probably in Lodz) with one of my sisters. While everybody was having a good time, my soul was experiencing deep torments. As I began to dance, I suddenly saw Jesus at my side, Jesus racked with pain, stripped of His clothing, all covered with wounds, who spoke these words to me: “How long shall I put up with you and how long will you keep putting me off?” At the moment the charming music stopped, and the company I was with vanished from my sight; there remained Jesus and I. I took a seat by my dear sister, pretending to have a headache in order to cover up what took place in my soul. After a while I slipped out unnoticed, leaving my sister and all my companions behind and made my way to the Cathedral of St. Stanislaus Kostka. It was almost twilight; there were only a few people in the Cathedral. Paying no attention to what was happening around me, I fell prostrate before the Blessed Sacrament and begged the Lord to be good enough to give me to understand what I should do next. Then I heard these words: “Go at once to Warsaw; you will enter a convent there” (Diary of St. Faustina, 9-10).

And so, it began. Maria Faustina went to Warsaw, entered a convent and Jesus commissioned her to begin recording His plea for humanity's return to God.

Through St. Maria Faustina, Jesus shows us how to prepare for the day of justice. He reminds us that we are living in a time of grace and that all people have the chance during this time to turn from darkness to light, to turn from evil to good, to rise from death to life. He awaits the return of fallen humanity. He desires to bathe humanity in the water and blood that flows from His pierced side — from His wounded Heart. It is a message of mercy — a message of forgiveness — a call to conversion and transformation — a call to be free in the love and peace of the suffering, crucified and risen Jesus.
The image and the entire devotion to The Divine Mercy are especially understood in the celebration of the Holy Sacrifice of the Mass and in adoration of the Blessed Sacrament. The soul is transformed by the grace and mercy which flows from the Sacred Species, enabling us to be true disciples of mercy through our prayer, our words, and our actions.

There has been a strong call from the Holy Father to establish chapels for adoration of the Blessed Sacrament throughout the world. I, too, felt the need for such a chapel here at St. Stanislaus Kostka from the beginning of my pastorate. Life in the parish is all consuming with little time available even to think about such an endeavor, but the desire for a sanctuary continued to burn. While Our Lady's work on the exterior of the church was under way, I began to labor over the possibility of establishing a Divine Mercy Chapel of perpetual adoration of the Blessed Sacrament. We had the space but no money, so I resigned myself to the belief that if Our Lady wanted the sanctuary, she would provide the means.
