Undue emphasis on the power of demons can serve to excuse our own sinful actions and mitigate our sense of responsibility for the harm we inflict on others. There are those who see Satan and his demons under every rock and behind every tree. To them, the world is one vast supernatural battlefield. Confronting and rebuking demons becomes a daily exercise. Aside from being unscriptural, this approach often results in a fearful and paranoid existence, a life with little joy and happiness, reminiscent of the superstitious tendencies of medieval Christians.
Humans are morally responsible for the evil they allow to enter their lives.
The fact of sin makes salvation necessary. All humans need the deliverance God offers through Jesus Christ. Jesus has won the victory over Satan. All believers have a part in that victory. We need not fear Satan and his demons.
