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 Malachi 3, Austin-Sparks considers the prophet as an end-time voice preparing the way for the Lord’s coming, and links Malachi with John the Baptist, Elijah, and Paul. He contrasts outward religious activity with wholehearted devotion, then turns to Malachi’s picture of the dishonoured altar and God’s perfect provision in Christ. The message calls readers to give the Lord their undivided allegiance and to find their acceptance in Christ alone.
