This sermon emphasizes the divine authority and practical value of all Scripture, affirming that it is 'God-breathed' and essential for teaching, correction, and spiritual growth. It distinguishes between different literary genres in the Bible—law, prophecy, history, wisdom literature, the Gospels, and epistles—urging believers to interpret each according to its intended purpose rather than applying all passages uniformly. The preacher warns against misapplying principles as commands, treating promises as guarantees, or reducing Scripture to legalistic rules, especially in light of cultural and historical context. He encourages a humble, discerning approach to Scripture, reminding listeners that while some passages may seem dull or confusing, they are still profitable when understood in their proper category, and that the ultimate goal is not mere knowledge but a deeper relationship with God through His revealed Word.
