'Joy' in the Bible

After all, to the person who is good in God's sight, he gives wisdom, knowledge, and joy, but to the sinner he gives the troublesome task of acquiring and accumulating in order to leave it to someone who is good in the sight of God. This also is pointless and chasing after the wind.

I concluded that it is worthwhile for people to find joy in their accomplishments, because that is their inheritance, since who can see what will exist after them?

Find joy in living with your wife whom you love every day of your pointless life that God gave you on earth, because this is your life assignment and your work to do on earth.
