What were the three messages from the Miracle of Fatima?

The three messages from the Miracle of Fatima, delivered by the Virgin Mary to three shepherd children in 1917, include a call to repentance and conversion, the importance of praying the Rosary for world peace, and a prophetic vision of future events, including the suffering of humanity and the necessity of devotion to the Immaculate Heart of Mary. The first message emphasized the need for penance, the second encouraged prayer as a means to avert war, and the third revealed a vision of the consequences of humanity's sins, which necessitated a response of faith and devotion.
