For many, the National Christian Foundation is not a household name. It doesn’t even have a Wikipedia page. But the meteoric rise of the 31-year-old organization is remarkable. For its first dozen years of existence, founder Terry Parker ran it with the help of just one assistant. By 2005, it broke into the Chronicle of Philanthropy’s list of the 400 highest-grossing charities. Foundation leaders attributed its rise to increasing expertise in handling non-traditional gifts—donations besides the usual cash or stocks. By 2012, the foundation was the 19th biggest American recipient of private gifts, topping Harvard, Yale, and the American Heart Association (among others) in donations collected—$665 million that year. In September, the Georgia-based foundation announced it had given away its four billionth dollar since its founding in 1982. That dollar, and a lot more, went to an orphanage in Thailand that houses and educates children rescued from the sex trade. Though denied headlines, the impressive achievements of this foundation are classic examples of the generosity of faithful givers.
