King Solomon pondered long and hard the meaning of life. He says in Ecclesiastes over and over that life is "vanity and a striving after the wind.”
I have seen the business that God has given to the children of man to be busy with. He 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. I perceived that there is nothing better for them than to be joyful and to do good as long as they live; also that everyone should eat and drink and take pleasure in all his toil—this is God's gift to man. I perceived that whatever God does endures forever; nothing can be added to it, nor anything taken from it. God has done it, so that people fear before him.
When it comes down to it, I ponder life along with wise King Solomon. If it is all nothingness, what is the point?
The point is we don't know and in this life we never will. So let’s just take God’s gift. Be joyful, do good, toil and rejoice in life. Trust that "God endures forever" and he has put eternity in our hearts. It is all we need to know. It is enough.
