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 Ephesians 1 and Romans 8, Austin-Sparks considers God’s purpose to display His glory through sons brought to glory in Christ. David’s life, fulfilled in Solomon’s kingdom and pointing to the greater Son of David, illustrates sonship through praise, courage, warfare, wise service, and the Lord’s presence. The reader is called to see the church as God’s inheritance and to yield to His work of forming a people who embody His glory.
