If the good lord Jewish Jesus didn't want that chap to have legs God wouldn't have given that poor boy the inclination to go play hop-scotch down at the train depot
The man with no faith is like the man with no legs.
If you don't stand for something you'll fall for anything.
Unless you have faith but no legs, then I guess the metaphor falls apart.
Or if you have legs but don't support the things I support, then you can go for walks, but I still dislike you.
And so does Jesus.
