Holy stubbornness

There was a big old house there, and I was struck by some words carved on the main facade of the building. I was told that they reflected the stubbornness of the admirable fellow who owned the house. From the building, through a little door set into the outer wall, he had a direct means of exit from the city. But the civic authorities made him block it up. He complied, but he had this inscription put over the window on the facade: Where one door closes, another door opens. There's stubbornness for you! Are you and I like that in our affairs? When something doesn't work out in our daily struggle, well then, tomorrow it will! My children, be stubborn. Raise your stubbornness to the supernatural level.
