Jesus revealed to St. Faustina that the message of Divine Mercy is itself a prophetic sign: "Speak to the world about My mercy; let all mankind recognize My unfathomable mercy. It is a sign for the end times; after it will come the day of justice. While there is still time, let them have recourse to the fount of My mercy." (Diary 848). He further warned: "Secretary of My mercy, write, tell souls about this great mercy of Mine, because the awful day, the day of My justice, is near." (Diary 965). And again: "Before the Day of Justice, I am sending the Day of Mercy." (Diary 1588). These passages establish the Divine Mercy devotion as the final period of grace before God's judgment upon the world.
