What does Ecclesiastes teach about the purpose of life?

The book of Ecclesiastes repeatedly emphasizes the vanity of life apart from God. It explores the futility of pursuits that do not acknowledge the Creator. According to Ecclesiastes 3:11, God has placed eternity in our hearts, leading us to seek genuine meaning and purpose through Him. Without recognizing God's sovereignty and the salvation offered through Christ, individuals are left to grapple with emptiness and dissatisfaction, making it essential for Christians to share this message of hope.
