So I've read a book about the attributes of God that was very eye-opening. It discussed things like His omniscience (all knowledge), His omnipotence (all power), His infinitude (all time), and the like.

Then last night, I got to thinking about the attributes of Satan. Obviously, Satan is under God's authority and God created him and allows him to exist (for now, anyway), but what attributes does Satan posses?

More specifically, is he omnipresent (everywhere)? I mean, many of us claim that we are tempted by Satan, but how can he be more than one place if he's not omnipresent? Is he omnipotent (knowledge)? He seems to know each of our weaknesses and tempts us with them.

Is Satan just one being, or is do his "angels" assist him?

Just some questions I really couldn't answer, but think would be important to discuss. After all, if we can understand the enemy better, maybe we can fight against him more effectively.
