Perhaps we do not know what love is: it would not surprise me a great deal to learn this, for love consists, not in the extent of our happiness, but in the firmness of our determination to try to please God in everything, and to endeavor, in all possible ways, not to offend Him, and to pray Him ever to advance the honor and glory of His Son and the growth of the Catholic Church. Those are the signs of love; do not imagine that the important thing is never to be thinking of anything else and that if your mind becomes slightly distracted all is lost.
