In the Bible a demon is a malevolent spirit, fallen angel, or unclean or evil spirit that follows and obeys Satan (the devil).
Key verse about Demon: When he arrived at the other side in the region of the Gadarenes, two demon-possessed men coming from the tombs met him. They were so violent that no one could pass that way (Matthew 8:28, NIV).
A lifelong student of the Bible, Peter DeHaan, PhD, wrote the 1,000-page website ABibleADay.com to encourage people to explore the Bible. His main blog and many books urge Christians to push past the status quo and reconsider how they practice their faith in every area of their lives.
