In this sermon, the preacher emphasizes the intensity of the message of punishment on a privileged people who have heard and rejected the Gospel. The book of Obadiah, with its brevity and clear language, serves as a powerful reminder of the consequences of turning away from God. The preacher urges the audience to examine their hearts and truly accept the Gospel, rather than relying on intellectual knowledge alone. The sermon also highlights the concept of the day of the Lord, a strong warning against an ungodly world and the futility of human efforts to save oneself.
