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)

Reading Revelation through its opening vision of Christ and the seven lamps of fire, Austin-Sparks presents the churches as tested by the Holy Spirit in the light of all they have received. He traces the searching call to return to first love and to stand in God’s faithfulness, then looks to Revelation’s consummation, where Christ is the beginning and end and divine life fills God’s creation. The message calls readers to heed the Spirit’s searching and embody Christ’s life. First published in "A Witness and A Testimony" magazines, 1961.
