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 Paul’s account of the gospel in 1 Corinthians 15, Austin-Sparks reads “the second Man” and “the last Adam” as the two heads of human history: Adam, whose disobedience brings ruin, and Christ, who enters humanity to undo its damage. He contrasts humanity’s loss of peace, rest, security, and dominion with what Christ brings, calling readers to see the greatness of His work against the full measure of human failure.
