A.B. Simpson emphasizes the importance of living a life directed towards God, rather than wasting efforts on superficial pursuits that ultimately lead to emptiness. He illustrates this through the metaphor of a steward who builds a wall around a demolished castle, symbolizing how many invest in the outward forms of life while neglecting true value. Simpson urges listeners to find their true purpose in God, discover their own worth, and engage in meaningful work that contributes to the greater good. He highlights that true satisfaction comes from a relationship with God, which fills the void that worldly pursuits cannot. The sermon calls for a return to God, self-discovery, and a commitment to impactful living.

C.H. Spurgeon emphasizes that true satisfaction can only be found in the love and presence of the Lord, as illustrated by Solomon's reflections on his own pursuits, which he deemed meaningless. Despite his wealth and pleasures, Solomon concluded that everything under the sun is vanity, a mere chasing after the wind. Spurgeon urges believers not to seek fulfillment in worldly pleasures, as they ultimately lead to emptiness. Instead, he highlights that embracing Jesus and dwelling in His love brings true contentment, regardless of life's circumstances. The sermon calls for a deep reliance on Christ as the ultimate source of joy and satisfaction.
