Jesus revealed to St. Faustina the relationship between His mercy and His justice: "Before I come as a just Judge, I first open wide the door of My mercy. He who refuses to pass through the door of My mercy must pass through the door of My justice." (Diary 1146). In an earlier entry, He warned: "Write this: before I come as the Just Judge, I am coming first as the King of Mercy. Before the day of justice arrives, there will be given to people a sign in the heavens of this sort: all light in the heavens will be extinguished, and there will be great darkness over the whole earth. Then the sign of the Cross will be seen in the sky, and from the openings where the hands and the feet of the Saviour were nailed will come forth great lights which will light up the earth for a period of time. This will take place shortly before the last day." (Diary 83).
