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 the 144,000 on Mount Zion in Revelation 14, Austin-Sparks considers what it means to follow the Lamb wherever He goes. He traces the Lamb from God’s eternal purpose and the Cross through the path of discipleship to Revelation’s vision of the holy city, where the Lamb embodies God’s purpose in a people and brings together loving devotion and divine government. From “A Witness and A Testimony” magazines, 1952 (Volumes 30-1,3,4,5,6).
