Biblical Understanding based on the Record of Scripture
Satan is not a name, it is a description, and it means adversary. Sometimes we think of Satan and the demons as constantly trying to disrupt our lives and ruin our focus, but that is not our worst opposition. With free will, we can choose not to respond to temptation, but when we do respond, we are our own opposition. When we are drawn away by our own desires, the worst enemy we have is ourselves.
