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 Isaiah 52:13–53:12 and the question “To whom hath the arm of the Lord been revealed?”, Austin-Sparks explores how God’s power is revealed through the suffering Servant and the Cross. He follows Isaiah’s movement from the Cross to resurrection, recovery, and the Spirit’s work, calling readers to let God clear and rebuild His people and bring all things into unity in Christ. First published in "A Witness and A Testimony" magazines, 1958-1959.
