He is one of my favorite saints....
"The story is told of a client of Saint Thomas of Canterbury, who being sick, went to the saint's tomb to obtain a cure. He returned home cured. But then he thought to himself: "Suppose it would be better for my soul's salvation if I remained sick, what point then is there in being well?" In this frame of mind he went back and asked the saint to intercede with God that he grant what would be best for his eternal salvation. His illness returned and he was perfectly content with the turn things had taken, being fully persuaded that God had thus disposed of him for his own good. "
-- St. Alphonsus Liguori
