From Church Pop:
“In 1943, Our Lord appeared to Sister Lucia and told her that what he desired was the fulfillment of one’s duties in life and sacrifices that fell in accord with adherence to his Law. This type of penance, he said, was possible for everyone.”
In 1948, World Apostolate of Fatima co-founder John Haffert interviewed Sister Lucia.
She told him that the most important request of Fatima is the fulfillment of one’s daily duties and the sacrifices required according to God’s law. She said praying the Rosary will help one fulfill this obligation.
Our Lord and Our Lady also requested that we devote ourselves to Our Lady’s Immaculate Heart:
“Have pity on the Heart of your Most Holy Mother. It is covered with thorns with which ungrateful men pierce it at every moment, and there is no one to remove them with an act of reparation.” (Jesus to Sister Lucia in 1939)
