It's certainly one of those poems which has to be based on someone's story. I can't imagine anyone, even Kipling, coming up with this one on his own.

You got to love this verse:

I have been smit an' bruised, as warned would be the case,
An' turned my cheek to the smiter exactly as Scripture says;
But following that, I knocked him down an' led him up to Grace.

Cheerily,
