I have no details but have been asked to keep this person in prayer. We all know that there is power when two or three are gathered in His name, and if only one or two of you join me, we've got that covered!
Sweet Lord Jesus, you healed everybody who asked for your help. You even healed when that woman touched only the hem of your garment. I trust you to look lovingly down upon this friend and help her in her hour of need - give her strength, faith and whatever she needs while you work this out for her. And please take a moment to ensure all her medical personnel are on top of this matter, no matter what it may be.
