(1) FAITH: One of the most dramatic early cures that took place at Lourdes was that of Justin Bouhort who was not yet two years old. He was on the point of death when his mother said a prayer and plunged him into the icy water at the grotto for what seemed like a terribly long time, while the shocked onlookers screamed in protest. The child recovered within days. He lived long enough to attend Bernadette's canonization in Rome on December 8, 1933. What's so beautiful was the mother's faith, so abandoned to God that it seemed even reckless. Of course, the Lord did not let her down. Such spontaneous faith, not contrived, works miracles.
(2) OBEDIENCE: This was exemplified by St. John of the Cross. When one obeys God, all else, great sufferings included, no longer matter. Pleasing God became St. John's sole wish and what heavenly joy it was!
(3) ABANDONMENT: Abandonment in God leads to total freedom of the spirit. Nothing in the world can now perturb the peace and tranquility the soul experiences in the Lord. St. Therese of Lisieux comes to my mind.
