God has made everything beautiful in its time. Also, He has put eternity into man's heart, yet so that he cannot find out what God has done from the beginning to the end.
Queen once famously inquired, "Who wants to live forever?"
E'erbody Queen. E'erbody!
Now I will grant you that we may grow tired of the same ol, same ol of this life and desire it to be over at times. But that isn't because we don't want to live forever, it's because we don't want to live forever in a world like this. We all want there to be more to life than this life actually is. It is a deep desire that leads to the quiet despair of this life under the sun when there's no hope in anything beyond it.
