From St. (Padre Pio) Pius of Pietrelcina on his feast day...

Calm yourself and be quite certain that [the] shadows are not a punishment proportioned to your wickedness. You are not wicked, nor are you blinded by your own malice....What is this painful searching for God... which occupies you heart so incessantly? It is the effect of the love which draws you and the love which impels you.
