Christopher Love, The Mortified Christian:

A truly mortified man is like a warrior:  he will either kill or be killed.  He will kill his sins or else his sins will kill him.  Now examine yourselves in this:  are you only fencers, to sport and play with your lusts, or are you warriors who fight with an implacable opposition against sin?  Do you only give a slight scare to sin or have you given it a deadly wound?
