Jesus entrusted St. Faustina with a profound eschatological mission, telling her: "You will prepare the world for My final coming." (Diary 429). The Blessed Virgin Mary reinforced this mission, appearing to Faustina and saying: "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." (Diary 635). These revelations frame the entire Divine Mercy message as a final offer of grace before the Day of Justice.
