One more from Francis de Sales:

The more miserable we are, the more we ought to trust in God’s goodness and mercy.  Had God not created man, God would always have been good, but he would not have been actually merciful, since he would not have shown mercy to anyone; for to whom can mercy be shown except to the wretched?

You see, then, that the more we recognize ourselves as miserable, the greater the reason we have to trust in God, since there is absolutely nothing in us in which we could put our confidence.
