The lyrical concept for this song is short and sweet. Necrotizing Fasciitis means \"flesh eating bacteria\", which fits the aura of the song perfectly it is nasty. However, as is often true of great songs, there is an underlying metaphor in the text. In this case, the plague is Jesus. Kind of a dark metaphor huh? Well may, but the idea is very simple. Flesh, or more specifically the sinful nature of carnal self, is something that all humans struggle with, and Christ is the only true power for defeating that sinful nature. And so, we cry out for Him to infest our bodies and devour our flesh. EMBRACE THE PLAGUE!
