The sermon challenges listeners to examine the object of their trust, contrasting reliance on human alliances and self-righteousness with faith in God alone. It highlights the failure of Judah's leaders who sought security through political covenants rather than divine protection, illustrating how such efforts amount to a covenant with death. The central message rests on Isaiah's prophecy of a precious cornerstone laid in Zion, identified as Jesus Christ, upon whom believers must build their hope. Through the parable of the farmer, the preacher emphasizes that God's actions, whether in judgment or salvation, follow His wise and sovereign counsel. Ultimately, the text calls for repentance from self-reliance; instead, we must place exclusive faith in Christ, who is the only secure foundation for righteousness and deliverance.
