“He that sacrifices to God his property by alms-deeds, his honor by bearing insults, or his body by mortifications, by fasts and penitential rigours, offers to Him a part of himself and of what belongs to him; but he that sacrifices to God his will, by obedience, gives to Him all that he has, and can say: Lord, having given you my will, I have nothing more to give you.”

— St. Alphonsus Liguori
