Ecclesiastes 3:8 A time to love and a time to hate; A time for war and a time for peace.
Ecclesiastes 3:9 What advantage is there to the worker from that in which he labors?
Ecclesiastes 3:10 I have seen the endeavor which God has given the sons of men with which to occupy themselves.
Ecclesiastes 3:11 He has made everything beautiful in its time. He has also set eternity in their heart, yet so that man will not find out the work which God has done from the beginning even to the end.
Ecclesiastes 3:12 I know that there is nothing better for them than to be glad and to do good in one’s lifetime;
The verse centers on "seen", "endeavor", "given", "sons", "occupy", and "themselves". It is saying that the verse draws attention to "seen" and "endeavor", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 9's "What advantage is there to the worker..." into verse 11's "He has made everything beautiful in its...", so "seen" and "endeavor" belong inside that flow. In Ecclesiastes context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "seen" and "endeavor" with trust shaped by these words, not by a vague optimism outside the passage.
