St. Turibius of Magrovejo – 

Anxieties and sorrows have the capacity to remind us of our need for God and to start us on a spiritual search. The result of such a quest has to be some amount of good. This is not to suggest that trouble, itself is good. To the contrary, it is essentially bad. But when we are going through it, let us try to remember this: Bad though it is, suffering does have its good side. It is often in the dark valley that we realize the Good Shepherd at our side.
