The devil is one of the most overlooked, if not the most overlooked topic in the entire Bible, and this is not by accident. The devil is our enemy number one, and yet we barley talk about him let alone study him. And this is exactly want he wants. The last thing the devil wants is for his enemies, Christians, to talk and think about the devil. If he can make himself invisible, he has a great advantage at destroying peoples lives. The devil does not need to out right make us evil, he just needs to cause us to be distracted by the things of this world for example. The devil is out to kill us, and we need to be wide awake and ready.
Satan is another name for the devil, here are verses that talk about Satan
