If
God causes you to suffer much, it is a sign that He has great designs
for you, and that He certainly intends to make you a saint. And if
you wish to become a great saint, entreat Him yourself to give you
much opportunity for suffering; for there is no wood better to kindle
the fire of holy love than the wood of the Cross, which Christ used
for His own great sacrifice of boundless charity.
