In this verse, Paul is addressing the Corinthians by questioning whether his teachings are based solely on human wisdom or if they are supported by the divine Law. By doing so, he underscores the importance of grounding spiritual teachings in the authority of Scripture. Paul is making a case that his instructions and guidance are not just personal opinions but are rooted in the broader, timeless truths found in God's Law. This approach reassures believers that their faith is not based on transient human ideas but on the enduring wisdom of God.
Paul's rhetorical question serves to remind the Corinthians of the consistency and reliability of divine teachings. It encourages them to look beyond human authority and to seek validation and understanding through the Scriptures. This principle is applicable to all believers, urging them to align their lives with God's word, ensuring that their beliefs and actions are not just culturally or personally motivated but are in harmony with divine will. This alignment provides a solid foundation for faith and practice, fostering a deeper connection with God and a more authentic expression of Christian values.
