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)

Beginning with Zechariah’s vision of the golden lampstand and the word “Not by might, nor by power, but by My Spirit,” Austin-Sparks considers God’s testimony as the display of His glory. He traces the vessel and people entrusted with that testimony, their priestly and ruling functions, and the opposition they face, calling readers to depend on the Spirit and give themselves to God’s purpose.
