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)

“The Ultimate Issue of the Universe” presents worship—the unreserved Lordship of God—as the governing purpose of Scripture and the spiritual history of creation. Opening with Revelation’s vision of God and the Lamb as the temple and the end of the curse, Austin-Sparks traces the challenge to God’s supremacy and the Lamb’s answer. He calls readers to see Christian life as participation in God’s work, that he may be all in all. A Conference Message (as spoken).
