13 It is not hard to imagine, although We know it is a very difficult task fitly to describe, the love of evangelical poverty which burned within him. Everyone knows how he, because of the noble character bestowed on him by nature, loved to befriend the poor, and how, as St. Bonaventure has said, he was so filled with kindness that being "no mere hearer of the Gospel" he had decided never to deny help to the poor, especially if they in asking for assistance did so with the plea "for the love of God." ( Legenda Maior , Chap. I, No. 1) Divine grace completed in him the work of nature and brought him to the highest perfection. Having on one occasion refused alms to a poor man, he forthwith repented and felt impelled to go and seek him out so that by the very abundance of his charity he might succor this man in his poverty.
