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 Abraham’s call in Genesis and his naming as the friend of God, Austin-Sparks presents the Christian life as a pilgrimage into God’s heart. Its stages include separation from the world and the natural life, a heavenly outlook, sonship, and fellowship with God’s purpose, resurrection power, and suffering. The reader is called to follow this path in faith and obedience, sharing more fully in Christ. First published in "A Witness and A Testimony" magazines, 1964, with the following statement: (The following messages are from the series given at the conference in Switzerland this year [1964]. It is printed here practically as it was spoken. In due course we expect that the whole series will be published in book form.).
