St. Faustina is associated with the revelations of Merciful Jesus, the prophetic mission of proclaiming the biblical truth about the merciful love of God to man to the world, with the devotion to Divine Mercy and the new school of spirituality. She is less frequently mentioned in relation with her revelations of Our Lady, and yet in the Diary, dozens of meetings of the Apostle of Divine Mercy with Mary are reported. One revelation was a special occasion, because it talks about the extraordinary role of St. St. Faustina in Divine Mercy plans. On the Feast of the Annunciation of 1936, in the convent chapel at ul. Żytnia in Warsaw, Sister Faustina saw the Mother of God, who told her: I gave the Savior to the world; as for you, you have to speak to the world about His great mercy and prepare the world for the Second Coming of Him who will come, not as a merciful Savior, but as a just Judge. Oh, how terrible is that day! Determined is the day of justice, the day of divine wrath. The angels tremble before it. Speak to souls about this great mercy while it is still the time for [granting] mercy. If you keep silent now, you will be answering for a great number of souls on that terrible day. Fear nothing. Be faithful to the end. I sympathize with you (Diary, 635). This message from the Mother of God also applies to us and impels us to bring the message of the merciful love of God to man to the world by testimony of life, deed, word and prayer.
