Here’s the question: “Can believers have a demon?”
Here’s the answer: “Yes, but why would thy want one? They’re not pets.”
In the early church they believed that a believer could have a demon if they had carried it over to their new life after being born again. This is still true today. If you have an area of your life that you have not surrendered to the Lordship of Jesus there may be demonic interference keeping you from walking fully with the Lord. The early church’s solution: be discipled by a more mature believer to learn all the basics of the faith you now confess. Secondly, be baptized by immersion in water in obedience to the Lord’s command. A sign of seriousness about Jesus.
The second way a believer can be demonized is through willful disobedience or rebellion. An early Church Father (Chrysostom) said that the way you wrestle with the darkness and win is by becoming light. In answer to the question: “How do we wrestle against spiritual hosts of wickedness?” his answer was: “By becoming good.”
He went on to say: “For wickedness is contrary to good, and light drives away darkness. If we ourselves too be darkness, we shall inevitably be taken captive. How then shall we overcome? If, what they (the demons) are by nature, that we become by choice, we are surely to be vanquished.”
In other words, if you chose to walk in any form of darkness then be sure you will meet a demon or two as that is where they live. And, don’t complain as you choose to live there with them; simply enjoy their company or plan a quick move to a new neighbourhood.
Want to defeat the Devil in your life? Be discipled in the faith, obey the Word, , get baptized if you are not already, and deal with any darkness (evil or wrong doing) in your life. Chose to walk in the light because that is where Jesus lives!
