F.B. Meyer emphasizes the divine partnership in the act of building, where man constructs outwardly while God sanctifies inwardly. He illustrates this cooperation through the example of education, highlighting that while we can shape a child's life with our actions and teachings, it is ultimately God who must bless and hallow these efforts. Meyer urges that our endeavors, whether in preaching or parenting, must be infused with the Holy Spirit to truly achieve their purpose. He reminds us that holiness comes from God's presence, and we should strive for our lives to be temples filled with His glory. The sermon calls for a deep reverence for God's role in our daily activities and the importance of seeking His sanctification.
