I wish I could persuade everyone to be devoted to this glorious saint, for I have great experience of the blessings he can obtain from God.  I have never known anyone to be devoted to him and render him particular services who did not noticably advance in virtue, for he gives very real help to souls who commend themselves to him.  For some years now, I think, I have made some request of him every year on his festival and have always had it granted.  If my petition is in any way ill directed, he directs it aright for my greater good.
