Chuck Smith emphasizes the futility of relying on human effort to build the church and protect our cities, reminding us that without the Lord's involvement, all labor is in vain. He highlights the alarming statistics of declining faith and the dangers posed by modern threats, urging believers to trust in God's promise to build His house and keep His people safe. Smith reassures that true prosperity comes from seeking God rather than material pursuits, and that peace and success are gifts from God to those who trust in Him.
