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 Inner Man of the Heart” examines the distinction between spirit, soul, and body, and the new birth by which the spirit is joined to the Lord. Drawing on Scripture including 1 Thessalonians 5:23, Romans 8, and the parable of the Prodigal Son, Austin-Sparks describes a life shaped by Christ’s resurrection rather than natural strength. Readers are called to walk by the Spirit, seek discernment, and surrender human impulses to God’s purposes. First published in "A Witness and A Testimony" magazines, 1926.
