T. Austin-Sparks emphasizes the role of the Cross in the nations, asserting that the Church embodies the Cross as it reaches out to the world. He explains that the Apostles preached Christ crucified in pairs, highlighting the importance of corporate testimony in evangelism. The Church is seen as the vessel of witness, tasked with holding the earth for its rightful Lord, Jesus Christ. Sparks notes that while the nations may not be fully saved now, they still declare Christ's authority through the Church's presence. Ultimately, he warns that Satan seeks to divide the Church, and only through the deep work of the Cross can believers effectively counter his schemes.
