T. Austin-Sparks emphasizes the Church's vocation as standing firm against the temptations and pressures of the Evil One, drawing parallels between Jesus' temptation in the wilderness and the Church's role in prayer. He highlights the importance of recognizing the true nature of God's kingdom, power, and glory, which are often hidden and not displayed like the ostentatious offers of the enemy. The sermon calls believers to maintain their testimony and faith in God's eternal promises, resisting the allure of immediate gratification that leads away from God's ultimate purpose. Sparks encourages the Church to occupy a prayerful position, standing in the gap for God's rights against the adversary's claims. Ultimately, he asserts that the Church's mission is to uphold the truth that God's kingdom, power, and glory belong to Him forever.
