T. Austin-Sparks emphasizes the profound relationship between God and Moses, illustrating how Moses' deep commitment to God's purpose exemplifies true power with God. He argues that Moses, despite his human frailties, stood in intercession for the people of Israel, demonstrating a heart aligned with God's intentions and a willingness to sacrifice his own standing for their sake. This relationship reveals that God seeks individuals who are utterly devoted to His purpose, not merely to the work of ministry, but to the people involved. Sparks challenges the congregation to reflect on their own commitments and the depth of their love for God's people, urging them to embody the same heart of responsibility and love that Moses displayed. Ultimately, he calls for a generation of believers who are committed to God's purpose in the Church, emphasizing that true service is born from love and a shared destiny with God's people.

T. Austin-Sparks emphasizes the significance of spiritual excellence through the example of David's mighty men, who exemplified different levels of commitment and effectiveness in their service to God. He highlights that while many served David, only a few attained the highest standard of greatness, which requires a deep perception of God's will, personal responsibility, and spiritual stamina. The sermon challenges believers to strive for a first-rate spiritual life, recognizing that true greatness involves enduring commitment and faith in God's purpose, even when it seems risky or unpopular. Sparks draws parallels to the Apostle Paul, who also sought to attain the highest calling in Christ, urging listeners to reflect on their own spiritual journey and commitment to God's full thought. Ultimately, the message calls for a response to God's call for deeper dedication and service.
