The story behind a classic devotional.
They were kids raised in a tiny Midwest country town (Thayer, Iowa, current population 48), who met, fell in love and got married, with missionary service on their hearts. (That calling was a big change from his job as a telegraph operator!) After Bible school, they headed for Japan in 1901 as independent missionaries. Through their bold “Every Creature Crusade” (1912-1918) they hoped to reach every home in Japan with the Gospel via evangelistic rallies and a daytime Bible training school, co-founding the Oriental Missionary Society (now known as OMS International). But his declining health cut short their work. She'd later write a now well-known devotional book, Streams in the Desert. Their names: Charles and Lettie Cowman.
With Charles' health problems ending their missionary work in Japan, they returned to the United States in 1918. During his final, six-year-long illness, Lettie wrote a daily devotional out of her life's lessons of fellowship with God amidst hardship.
After Charles' death in 1924, Lettie found a note he'd written and put in her Bible: “Go on with my unfinished work.” And she did—though not quite what she and Charles had envisioned it when they first went to Japan. As young missionaries they hoped to evangelize Japan through literature distribution in five years, then do the same in Korea and China. Instead, she would write Charles' biography and pour herself into the OMS ministry, watching it expand throughout the world. Her husband had been the mission's first president, another man its second, and when that man died four years after Charles, Lettie became the mission's third president. Besides leading the mission, she spoke widely overseas, including Wales, Ethiopia, Finland, and Colombia.
Besides her mission leadership, her preparation of devotional materials put her name in the history of Christian publishing. Best known are her compilations, Streams in the Desert (copyright 1925) and a follow-up, Springs in the Valley (1939). “Compiled” is the key word, as both books are “cut-and-paste” devotions of her own spiritual reflections incorporating quotations from authors and ministers of the early evangelical movement--like Charles Spurgeon, F.B. Meyer, George Mueller, Christina Rossetti and Samuel Rutherford (Scottish Presbyterian, 1600s). While writing these devotionals, she continued to lead the mission and traveled widely, and eventually stepping away as its president in 1949, the year she turned 79. She would live another decade-plus, dying on Easter Sunday in 1960.
Streams in the Desert has never been out of print since its first publication in 1925, with an estimated six million copies in multiple languages sold. It's also available online--a publishing venue completely unknown when it was written!
