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)

Austin-Sparks traces the church’s ministry through 2 Corinthians: a shared calling to serve with Christ, even through suffering, and to be living letters written by the Spirit. Contrasting the ministry of Moses with the new covenant, he turns to the unveiled face reflecting the Lord’s glory. The message calls believers to let Christ’s life be seen, preach Him rather than themselves, and not faint.
