" There is a legend that in every age God spares the world the destruction it deserves only because there are a certain number of Abrahams, righteous men and women who keep the world alive by their righteousness and their prayers, by the mass and the gravity of their righteousness reverberating on the walls of the divine mercy. No one but God knows who these righteous are or how many there are. "
