T. Austin-Sparks emphasizes that true spiritual enlargement often comes through straitening, highlighting that human efforts can lead to artificial growth devoid of spiritual reality. He argues that God often begins at a point of zero, where human hope is lost, to demonstrate His power and purpose through the Cross. The sermon critiques the reliance on human ingenuity in church leadership and missionary work, advocating for a return to a Spirit-led, organic understanding of the Church as the Body of Christ. Sparks calls for a reformation that prioritizes Christ's presence and purpose over institutional structures, suggesting that true evangelization is about the increase of Christ's presence in the world. He concludes that a new revelation of Christ is essential for overcoming the limitations of organized Christianity and achieving spiritual fullness.
