Saint Faustina is commonly associated with her revelations of Merciful Jesus and not so much with ones of the Virgin Mary. However, she experienced tens of such revelations. While She conversed with Sister Faustina, Mary revealed to her the mystery of Divine Mercy in her own life. She also instructed, reassured and accompanied the Saint in her prophetic mission of Mercy. She told her: Out of the depths of God’s Mercy, I am your Mother (Diary, 449) and I am not only the Queen of Heaven, but also the Mother of Mercy, and your Mother (Diary, 330).
The Blessed Virgin was, for Sister Faustina, primarily the Mother of the Son of God – the Embodiment of Mercy – and thanks to the Divine Mercy, also the mother of every human being. As the caring best Mother of all and a Mistress of spiritual life, she instructed her regarding the contemplation of God in her soul, regarding obedience to the will of God, the art of lovingly accepting one’s own cross and concern for the virtues that condition the attitude of trust in God and mercy towards our fellow human beings. I saw the Mother of God, Sister Faustina noted, who said to me, “Oh, how pleasing to God is the soul that follows faithfully the inspirations of His grace! 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 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).
