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)

Tracing the Cross through Paul’s letters, Austin-Sparks presents it as the all-inclusive ground of Christian life and the means by which believers pass from the natural to the spiritual, receive the ministry of the unveiled face, and grow into sonship. From resurrection ground in Ephesians to the suffering and resurrection power of Philippians, the messages call readers to embrace the Cross and its work, finding freedom from narrow horizons and victory in Christ. From spoken messages given in 1967.
