“Charles and Lettie Cowman came to Japan as independent missionaries in 1901 and later founded the Oriental Missionary Society and worked closely with the Holiness Church in Japan. Their commitment to missions had come several years after they had married and settled into an affluent lifestyle - Charles, in management at Western Union Telegraph Company, and Lettie the daughter of a banker. They had only recently been converted and were attending a mission conference at Moody Church in Chicago where A. B. Simpson (founder of the Christian and Missionary Alliance) was the speaker. Following the emotionally charged message, an offering was taken. So moved was Charles that he contributed ‘a roll of bills that represented a month’s salary.’ But the offering had just begun. ‘Then, as the enthusiasm mounted higher, people wanted to give their jewelry and even watches. Charles disentangled his solid gold watch and chain, and looked down at the large diamond on Lettie’s engagement ring, as if to say: ‘Surely you are going to come along with me in this, aren’t you?’
“The connections with Moody Memorial Church, A. B. Simpson, the Holiness Movement, and their student days at Moody Bible Institute put the Cowmans squarely in the camp of turn-of-the-century Fundamentalism - as did their separations from the world. After her conversion, Lettie stood by her piano and ‘yielded’ her stacks of dance music, operas, popular songs, and secular books to God, never to again be involved in such wordly amusements.” - Ruth A. Tucker, From Jerusalem to Irian Jaya: A Biographical History of Christian Missions.
