From Bill Gates has included a book about the “prosperity gospel” in his summer reading list:

I have also seen how this line of thinking affected members of my own extended family. All four of my grandparents were deeply devout members of a Christian sect who believed that if you got sick, it must be because you did something to deserve it.

He died thinking she had caused his illness by committing some unknown sin.
