In reality when you really think long and hard many jobs are kind of useless. I could argue that in the grand scheme of things our existence might be completely useless and irrelevant. Yet we spend our short existence doing things which have almost no meaning, some of us try to impress our friends and neighbors. Put up some accomplishments on our useless CV before we turn into dust. Others will raise their offspring…
The words of the Teacher, son of David, king in Jerusalem:
2 “Meaningless! Meaningless!” says the Teacher. “Utterly meaningless! Everything is meaningless.”
3 What do people gain from all their labors at which they toil under the sun? 4 Generations come and generations go, but the earth remains forever.
and it ends with:
Now all has been heard; here is the conclusion of the matter: Fear God and keep his commandments, for this is the duty of all mankind. 14 For God will bring every deed into judgment, including every hidden thing, whether it is good or evil.
