St. Bernadette. Our Lady to St Bernadette. Our Lady called Bernadette, "My Most Precious Child," and said to her, "I do not promise to make you happy in this world, but in the next." These words, spoken at the third apparition on February 18, 1858 were a prophesy of Bernadette's life. This was the promise in return for Bernadette's total compliance with the will of the heavenly Mother.
