T. Austin-Sparks discusses 'The Great Schism' that occurred between the eternal times and the beginning of creation, emphasizing its tragic impact on humanity and the cosmos. He highlights the Apostle Paul's teachings in his later letters, particularly in Ephesians, which reveal the cosmic conflict between Christ and the forces of evil, led by Satan. Sparks explains that this disruption necessitates the re-gathering of all things in Christ, as humanity was originally created in Him but has since fallen into sin and separation from God. He stresses the importance of the Church's role in this spiritual warfare, equipping believers with the armor of God to stand against the wiles of the devil. Ultimately, the sermon calls for awareness of the ongoing battle for unity and the need for believers to actively engage in their spiritual defense.
