Bl. Pope John Paul II said in his address which he gave when he visited the tomb of Sister Faustina at the convent of the Sisters of Our Lady of Mercy in Lagiewniki, Poland, back in 1997.“There is nothing that man needs more than Divine Mercy. … And it is a message that is clear and understandable for everyone. Anyone can come here, look at this image of the merciful Jesus, his heart radiating grace, and hear in the depths of his own soul what Blessed Faustina heard: ‘Fear nothing; I am with you always.’ And if this person responds with a sincere heart: ‘Jesus, I trust in you,’ he will find comfort in all his anxieties and fears. ...
On the threshold of the third millennium I come to entrust to him once more my Petrine ministry: ‘Jesus, I trust in you!’ “The message of Divine Mercy has always been near and dear to me. It was an inexhaustible source of hope for the Polish people during World War II. This was also my personal experience, which I took with me to the See of St. Peter and which, in a sense, forms the image of this pontificate. I give thanks to divine Providence that I have been enabled to contribute personally to the fulfillment of Christ’s will, through the institution of the feast of Divine Mercy [in Poland]. … I pray unceasingly that God will have ‘mercy on us, and on the whole world.’”
