In his teaching on Ecclesiastes, Jonathan Harris shows that this book isn't about depression but finding purpose in life's temporary nature. Solomon calls us to "cast your bread upon the waters" - taking meaningful action despite uncertain outcomes. Jonathan points out that even when our efforts don't succeed, God remembers work done with the right heart. The message is clear: rather than being paralyzed by life's unpredictability, we should "double down on doing good" while we still have time, finding joy in living purposefully before God.
