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 Representation of the Invisible God” traces God’s purpose to be made known through Christ, the image of the invisible God, and through the Church, conformed to his image. Beginning with Genesis 1:26 and the New Testament’s language of image and likeness, Austin-Sparks considers identification with Christ, the Holy Spirit’s power, and service as representation. He calls readers to pursue spiritual knowledge of Christ and embody his life as his witnesses. First published in "A Witness and A Testimony" magazines, 1943-44.
