Thy is Dead, so is "The End"

 Found this book called A SERMON FOR THE WORST MAN ON EARTH by Charles Spurgeon, who lived and died roughly the same time as the dinosaurs and William Shakespeare.

The DESCRIPTION of the book says Spurgeon shows that, among other things, "a sense of sinnership confers no right to mercy."
First of all, does ANYTHING confer a right to mercy?  Secondly, if it DOESN'T confer a right to mercy, how is that relevant?  Does it confer a withdrawal of mercy?  If not, then what the hell is the point in making such an observation????

Ug.
