This sermon on Ecclesiastes 3:16–4:16 explores the vanity of life under the sun when detached from God's wisdom. Solomon evaluates different pursuits—pleasure, power, wealth, and labor—showing how each ultimately fails to bring lasting fulfillment. The preacher emphasizes that human courts are flawed, oppression is rampant, and even great rulers are eventually forgotten. The futility of self-centered work and the loneliness of individualism highlight the need for wisdom, which alone leads to a meaningful life. True purpose is found in knowing God, obeying His law, and building His kingdom, which alone endures beyond earthly vanity.
