I produced this teaching some years ago (1995 I think) when I set up a healing service in a local church.
It covers some of the basic questions and will get you started. I remember people finding it quite helpful.
I think there are something like 6-8 sessions of bible teaching - its years since I've looked at it.
Its biblical and it does not shrink from the tough questions. Hope you find it useful.Healmin.zip, 60KB zip file, < 1 min download
