This chapter opens with one of the most famous passages in all of literature: there is a season for everything under heaven. The Preacher lists fourteen pairs of opposites: times to be born and to die, to plant and to pluck up, to kill and to heal, to break down and to build up, to weep and to laugh, to mourn and to dance, to embrace and to refrain from embracing, to keep and to cast away, to tear and to sew, to keep silence and to speak, to love and to hate, and a time of war and a time of peace. The list isn't random. It covers the full range of human experience and says: all of it has its place. Then comes the question that follows naturally: what does the worker actually gain from all his labor?
The Preacher's answer is layered. God has made everything beautiful in its time. And God has placed eternity in the human heart, so that we sense there is something vast and purposeful happening. But no one can find out the work God makes from beginning to end. We live inside a design we cannot fully read. Given that, the Preacher draws the same quiet conclusion as before: there is nothing better than to rejoice and do good in one's life, to eat and drink and enjoy the fruit of one's labor, and this, he says plainly, is the gift of God. Whatever God does lasts forever. Nothing can be added to it or taken from it. God acts this way so that people will stand in awe before him.
Then the Preacher turns his gaze outward and sees something troubling: in the very places meant for judgment and righteousness, wickedness and iniquity are there instead. Corruption sits in the seat of justice. His response is not despair but a reckoning: God will judge the righteous and the wicked, for there is a time appointed for every purpose and every work.
He presses further still. God allows people to see their own condition clearly: that in their nature, they are like the beasts. The same fate comes to both: as the animal dies, so dies the man. Both share one breath, and man has no advantage over the beast in this. All go to one place, all come from dust, and all return to dust. The Preacher then asks the question he does not answer: who truly knows whether the spirit of man rises upward while the spirit of the beast descends into the earth?
And from that open, unresolved question, he draws his conclusion: there is nothing better than for a person to rejoice in their own work, for that is their portion. No one can bring them back to see what comes after.
