St. Faustina repeatedly warned the other sisters at her convent to pray for Poland because "a terrible war was coming." She frequently expressed urgency about an approaching catastrophe that would engulf their homeland. This prophecy was fulfilled when Nazi Germany invaded Poland on September 1, 1939 — less than a year after Faustina's death on October 5, 1938. The war brought unimaginable devastation to Poland: six million Polish citizens perished (including three million Polish Jews), Warsaw was reduced to rubble, and the entire nation suffered under brutal occupation for nearly six years. Faustina's prophetic warnings about the war, combined with her vision of the chastisement of Warsaw, demonstrate her gift of prophecy regarding the temporal fate of her homeland.
