Never Refuse Anyone Who Begs "For The Love Of God."

One of the expressions we use in ordinary speech always moved Francis profoundly whenver he heard it, and it was, "For the love of God." As soon as he would hear these words, they would excite him, work upon him, and enkindle him, as if an inner chord had been plucked by them. And he kept faithfully until his death the promise he made to himself when he was still living a worldly life, that he would never refuse a poor person who begged anything "for the love of God."
