Pain has a legitimate function – to warn you of something wrong. BUT after you have your warning the enemy jumps on a bad situation to make it worse with demons of pain.
Here is where your training in spiritual warfare becomes valuable. Bind that pain immediately in Jesus’ Name, then cast it out and tell it sharply NOT to return.
You should get instant relief. If not repeat and shout louder – he may be pretending to be deaf.
Your faith will get stronger every time you deal with the devil with the authority you have as a believer.
Jesus said, “As my father has sent me so send I you.” In other words, you have access to everything done through His name because you are a member of his family, his little brother or sister. Non-believers do not have this privilege.
Casting out demons is called by Jesus “children’s bread” meaning for you, the children. Children of the devil have no such power.
Now the devil always shows up again to test you to see if you are sincere. Dispatch him again and again as often as need be.
I taught this lesson in the Philippines two decades ago. One of the young women students came to me and whispered that she had a demon of pain and did exactly what I said. “And it left?” I wanted to know. “Yes,” she whispered.
“But then he came back the next night just as you said. And I cast him out again.”
I was so excited. The more people that know how to command and use the authority Jesus gave His people the more peace we have. This is what it means to live in the Kingdom of God.
