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 Hebrews 11:10 and Ezekiel 5:5, Austin-Sparks presents Jerusalem as the spiritual and heavenly expression of God’s people, fulfilled in the Church. He traces its features through Scripture: the overcomer, heavenly government, the Church’s universal calling, and the city’s clear, pure light, contrasting these with earthly vision and Babylonian mixture. The message calls readers to recover a heavenly vision and live in spiritual faithfulness. Meditations on the Spiritual Background of Jerusalem.
