Why trouble about the skin?

James Colquhoun, The Invalid’s year-book, 1880, p. 240.

Ah, would that they were as much in Earnest about the kernel as about the shell; would that they contended as eagerly for the jewel as they do for the casket that held it. He is risen, like the beautiful insect winging its way from its grub case; why trouble about the skin? and yet it is precious, as having once held that which is si prized. And perhaps our Lord Himself will look down in loving pity and forgive the dissensions begun out of
jealousy for him and his footpaths and tabernacles on earth.
