Nicholas Kristof, an op-ed columnist for The New York Times wrote a column in March 2015 entitled, "A Little Respect for Dr. Foster." Kristof makes clear that he isn't an evangelical Christian yet he says, "But I've been truly awed by those I've seen in so many remote places, combating illiteracy and warlords, famine and disease, humbly struggling to do the Lord's work as they see it … " He focuses on "Dr. Stephen Foster, 65, a white-haired missionary surgeon who has lived in Angola for 37 years—much of that in a period when the Angolan regime was Marxist and hostile to Christians."

"We were granted visas," [Foster] said, "by the very people who would tell us publicly, 'your churches are going to disappear in 20 years,' but privately, 'you are the only ones we know willing to serve in the midst of the fire.'"

Kristof writes, "One son contracted polio; a daughter survived cerebral malaria; and the family nearly starved when the area was besieged during war and Dr. Foster insisted on sharing the family rations with 100 famished villagers."

Kristof concludes: "The next time you hear someone at a cocktail party mock evangelicals, think of Dr. Foster and those like him. These are folks who don't so much proclaim the gospel as live it. They deserve better." (Although there's probably much more proclaiming than Kristof realizes. Dr. Foster's website carries the banner: Hope for Angola through healthcare, agriculture, education, and the Gospel of Jesus Christ.)
