According to Way of the Master Radio, Charles Butts, the booker for infamous Madalyn Murray O’Hair, has said that

“If you take a look at some of these scientific arguments, Ray Comfort came out with a bible specifically for that kind of thing. And so when that came out I certainly examined that. I finished reading the bible and decided all the questions that could be answered had been answered. And I had watched enough TV to know the sinner’s prayer, and I knelt in the livingroom of my home, accepted Jesus as my savior — and I’ve never, ever regretted it.

Butts was in charge of getting Madalyn Murray O’Hair television and radio spots, so that she could promote her point of view in the 60s and 70s: That there is no God, and prayer to Him in schools is unconstitutional.
