Prayer Request for Jim

I need to have you guys send a few prayers for my sister's husband, Jim.  He was diagnosed several months ago with a rare form of cancer in the nerves in his head.  They operated and did chemo and radiation for about 5 or 6 months.  They just found out that the tumor has grown and is almost at his brain.  He has been given weeks to months to live.  Please pray for his healing and for his salvation.  ~Lisa
