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 Revelation 3 and 12, especially the overcoming company’s victory through the Lamb’s blood, this book turns to the church’s position in Christ in the heavenlies and its calling to spiritual service and warfare. Through Ephesians, Austin-Sparks considers the believer’s inward strength, the cross, prayer, God’s armour, and the enemy’s tactics, calling readers to take their place by faith and stand there in dependence on Christ.
