On July 13, 1917, Mary showed the Fatima children a vision of hell, a vision of the greatest gift we all have – our free will. Today, more than ever, we are faced with the choice between good and evil; will we immerse ourselves in the light of Christ or embrace the darkness of His nemesis? The children were given this prayer to say: O my Jesus, forgive us our sins, save us from the fires of hell. Lead all souls to heaven, especially those most in need of Your mercy.
