Theodore Austin-Sparks (1888–1971) was a British evangelist and author. Born in London, he became a Christian at seventeen while listening to street-preachers in Glasgow, and was ordained a Baptist minister at twenty-four. In 1926 he left the denomination and, with like-minded Christians, founded a conference and training centre at Honor Oak in south-east London. From there he published the free magazine "A Witness and A Testimony" until his death, and his conference ministry took him across Europe, North America and Asia. He asked that his messages be shared freely and word for word. Source: Wikipedia (summarized; CC BY-SA)

Through Paul’s letter to the Philippians and the account of the gospel’s entry into Philippi in Acts 16, Austin-Sparks explores the surpassing worth of knowing Christ. He presents Christ as the source of fellowship and service, and calls readers to count other gains as loss, glory in Christ, and give themselves wholeheartedly to the interests of the gospel. First published in "A Witness and A Testimony" magazines, 1935.
