C. S. Lewis "When speaking about the reality of Satan and demonic activity, the danger is always twofold: To put way too much emphasis, or way too little." To some, there’s a demon behind every door. To others, demons are no longer among us. The truth is, there is a highly organized army of satanic forces operating in the world today, just as in Bible days. These evil spirits seek to inhabit human lives in order to find expression in this realm.
