T. Austin-Sparks emphasizes that God has a profound message for our hearts, demonstrated through the life of Jesus, who lived a spiritually rich life in a mundane world. He highlights that Christ's earthly existence was safeguarded by God to ensure that His value remained spiritual, not temporal, and that true appreciation of Christ comes from a heart transformed by the Spirit. Sparks urges believers to recognize that they are called to live ordinary lives on a higher spiritual level, empowered by the Holy Spirit, and to seek God's direction in their actions rather than relying on their own plans. He stresses the importance of being constituted and anointed by the Spirit to fulfill God's purpose effectively, warning against the church's tendency to operate without divine guidance. Ultimately, the sermon calls for repentance and submission to the Holy Spirit's leading to regain the church's impact in the world.
