I took for my advocate and lord the glorious St. Joseph, and commended myself to him... I do not remember even now that I have ever asked anything of him which he has failed to grant. I am astonished at the great favors which God has bestowed on me through this blessed saint, and at the perils from which He has freed me, both in body and in soul.  To other saints the Lord seems to have given grace to succor us in some of our necessities but of this glorious saint my experience is that he succors us in them all and that the Lord wishes to teach us that as He was Himself subject to him on earth (for, being His guardian and being called His father, he could command Him) just so in Heaven He still does all that he asks.
