Phillip Yancey toured the Yanghwajin Foreign Missionary Cemetery, built to honor 145 missionaries in South Korea. All of the missionaries died in their adopted country. Yancey writes:

Some of the gravestones date back more than a hundred years, and the caretakers have added stainless steel plaques to recount the stories of the missionaries buried there. Some faced persecution for leading protests against the brutal Japanese colonial rule. A couple with the Salvation Army began the long tradition of caring for Korean orphans. A scholarly Presbyterian contributed greatly to the Korean translation of the Bible. Two women pioneered education for girls by founding schools and ultimately a women's university. Another American woman, who came to Korea as a medical missionary, developed Braille suitable for the Korean language and established a school for the blind.

My favorite story was of S. F. Moore, who gave medical treatment to a butcher deathly ill with typhoid fever. The butcher survived and became a Christian, only to find that no church would admit him. (Korea's rigid class system scorned butchers, who dealt with "dead things" such as meat and leather, as the lowest social class.) Moore supported a freedom movement to fight such discrimination and organized a Butchers Church for outcasts and social underdogs. He died of typhoid fever at the age of 46.

Each plaque spelled out hardships of the men and women buried there. Many of the missionaries also lost children, buried in small graves beside them. Yet the fruit of their work lives on, in schools, libraries, hospitals, and church buildings dotting the landscape of modern South Korea …

To a nation steeped in hierarchy and dominated by its powerful neighbors China and Japan, the men and women buried here brought a gospel message of justice, compassion, and transformation. In comparison with much of Asia, South Korea has been unusually receptive to the Christian message; 30 percent of South Koreans identify as Christian. I spoke at one impressive church with 65,000 members—yet it is less than one-tenth the size of Seoul's largest church.
