I came into agreement with you and sent up a prayer that your husband can find sone relief. Hope it helps.
Can I make a suggestion? Since you say the medication isn't working for him then, why not treat it as if it is a spirit? Jesus gave us all authority over evil spirits.
You see in Psalm 23 it talks about thy rod and thy staff shall comfort me. The rod and staff are synbolic of power and authority, and they are very different!
the root word for power in Greek is dunamis which is our root word for dynamite. When there is an explosive power which changes things. The root word in Greek for Authority is exousia and means authority. Wjen Jesus was casting out demons He didn't pray to God, He used His Authority. When Jesus spoke to the turbulant sea and wind He used His authority.
And Jesus said all that He has done, we will do and more. You are a chid of God so you have this authority.
It's true that some spirits only go out by prayer and fasting, but not all of them. That just illustrates that some evil spirits are stronger than others, just like us. So by much prayer and fasting prolly means how close of a relationship do you have with your Lord? Is your relationship closer to the Lord than the evil spirit's is to it's master? Maybe!
So the worst thing that could happen is it don't leave and he still has a migrane. But if by exercising your authority over the evil spirits in Jesus Name, then command the spirit of Migranes to leave at once, he is not welcome and is cast out in Jesus Name which he is bound to obey.
And please, do not think that I am discouraging prayer at all. I am not discouraging prayer. I just think that every little bit helps and that we should be exercising our authority in Christ.
You could even lay hands on him if you want, you're his wife! Attack that spirit of Migranes! In Jesus Name !!! Get out!
I've listened to wuite a few of Derek Princes testimonies about when he casted out spirits. Sometimes it takes a bit of time. SOmetimes they will talk to you. And sometimes they refuse to leave. And Dereks reply was another command to leave in Jesus name. And many times they went ahead and left! Praise the Lord!!
Just a suggestion.
