T. Austin-Sparks emphasizes the supernatural nature of Christ's death and resurrection, arguing against the notion that Jesus' death was merely that of a martyr. He asserts that Christ's death is a spiritual power that addresses the root cause of death—sin—and leads to victory over it, while the resurrection is a divine act that underpins the foundation of Christianity. Sparks highlights that the Church itself is a supernatural entity, birthed by the Holy Spirit and existing in God's eternal plan, rather than a human creation. He calls for a recognition of the divine origin of the Church and its ongoing supernatural sustenance through the Spirit. Ultimately, the sermon underscores the necessity of discerning the spiritual from the natural in understanding the Church's mission and existence.
