Finally found a title that's been nagging me

I read this back in 98 or 99. Enjoyed it and 2 years ago thought to myself, I'd like to find that book and read it again. Was it called....The Godmakers?
I look that up, the covers seem all wrong and I'm CERTAIN that Frank Herbert didn't write it. The scenario also seems off from what I remember it being about. So it became an on again - off again obsession to find that book.
Finally gave the title The Godmakers another shot and found in Google images the cover I was looking for. It is indeed written by Frank Herbert. My brain. Such putty.
