How does Solomon illustrate the futility of human wisdom?

Throughout the Book of Ecclesiastes, Solomon examines the nature of wisdom and knowledge, concluding that while wisdom is better than foolishness, it still does not provide ultimate fulfillment when pursued apart from God. He states that increased knowledge can often result in increased sorrow, revealing that worldly wisdom lacks the capacity to answer life’s most profound questions without divine revelation. The preacher’s quest for understanding, devoid of God, ultimately leads to a recognition that true wisdom comes from a fear of the Lord and is fulfilled in Christ, reinforcing the idea that human efforts are insufficient without divine grace.
