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)

Opening with Romans 5 and the contrast between Adam and Christ, Austin-Sparks traces God’s purpose in the last Adam, the risen Christ, and the new creation. From “Christ in you” and the freedom Christ gives, he turns to Hebrews’ contrast between passing forms and the unshakable heavenly realities. The reader is called to live by Christ within and remain bound to what endures. First published in "A Witness and A Testimony" magazines, 1967-68 Volumes 45-6 - 46-4.
