I hate to throw this in, because I know it never easy on your side of the fence and easy for me to say, but the lord says give thanks in all things. That's good and bad, because the lord has a reason. That can be from the person themself accepting Jesus to maybe someone in the hospital needs witnessing to. I pray everyone keeps their faith strong in the lord. I pray for your aunt to be healed and for your family to find his peace,
BUT let me say one more thing. Lay your hands on her and pray for the lord Jesus to heal her and tell her to do the same. Tell her to rub her head and ask Jesus to please heal her.
Oh and one more thing. I don’t know if you like Joel Osteen but his mother has pulled out a lot of healing scripture. Print it out so she can read every day.
