Here "sin" is personified. "Sin" functions like a personal agent who wants to infect you with its disease so as to manipulate and control you. (Think of "Gollum" in "The Lord of the Rings.)
These ancient words are so relevant to me today. I am always in touch with drug, alcohol, porn, or whatever addicts, who contact me in hopes of rescue.
As I've written elsewhere, addiction (sin) is a "beast." ("Treating the Beast of Addiction") It wants to have you. When it gets its talons into your skin it desires to go deep, into heart and mind and soul. Sin, addiction, longs to have your very soul. When this happens, the fun is over. For a long time. Even, for a lifetime.
Today, when sin knocks, refuse to open the door. Rule over it.
