Oswald Chambers (1874–1917) was a prominent preacher, writer, and evangelist. He studied at The Art School in South Kensington, the University of Edinburg, and Dunoon Training School.
Chambers served as a YMCA chaplain to British Commonwealth soldiers during World War I. He also worked as a traveling speaker for the League of Prayer and as the main teacher of the Bible Training College. His preaching ministry reached Britain, America, and Japan.
Chambers’ books are mainly compilations of his messages that were transcribed by his wife, Gertrude or “Biddy” as he called her. The daily devotional My Utmost For His Highest was first published in 1927 and continues to be a best-seller. 24 essays and books, including Studies in The Sermon on Mount and Biblical Psychology, can be found in the Oswald Chambers Collection.
