T. Austin-Sparks emphasizes the significance of Jerusalem as a symbol of God's heavenly government, tracing its lineage from Melchizedek to the New Jerusalem in Revelation. He explains that the Church, represented as a city, is a spiritual entity that operates under divine governance, with certain saints sharing in Christ's authority. Sparks contrasts the true MYSTERY JERUSALEM with MYSTERY BABYLON, highlighting the hidden nature of God's city, which can only be understood through spiritual revelation. He underscores the importance of the Church's heavenly nature and its role in governing the world through prayer and spiritual union with Christ, despite earthly opposition. Ultimately, he calls believers to recognize their identity as citizens of this heavenly city, empowered to fulfill God's purposes through their connection with Him.
