A brief study of the Doctrine of Demons.


  • Demons are most probably angels who chose to follow Satan when he sinned (Matthew 12:24 and 25:41.)
  • Demons believe that God exist and they fear him (James 2:19).
  • Demons have a system of doctrine and they seek to spread that to mankind (1 Timothy 4:1).
  • Demons can cause both physical (Matthew 9:32-33) and mental illness (Matthew 17:15).
  • Demons are able to deceive believers into accepting false doctrine and wrong actions (Acts 5:3; 2 Corinthians 11.3-4; 1Timothy 4:1).
  • Demons can indwell and control people (Matthew 8:16 and 28-34). But they apparently cannot indwell believers because the Holy Spirit lives in every believer (1 John 4:4).
  • Idolatry and demonism are related (1 Corinthians 10.20-21).
  • Mankind will worship demons in the tribulation period (Revelation 9:20).
  • Believers are at war with demons (Ephesians 6:10-12; 1 Peter 5.7-9; 2 Timothy 2.26).
  • Believers have spiritual weapons and instructions so they can not be defeated by demons.
    • Armor  (Ephesians 6:13-18)
    • Be watchful, alert (1 Peter 5:7-9)
    • Resist them and chose fellowship with God and God’s will (James 4:7).
    • Do not take demons lightly or get into a situation where demons can take advantage of you (Ephesians 4:27).
