'Activity' in the Bible

And I set my mind to seek and explore by [man’s] wisdom all [human activity] that has been done under heaven. It is a miserable business and a burdensome task which God has given the sons of men with which to be busy and distressed.

I observed every activity done on earth. My conclusion: all of it is pointless like chasing after the wind.

There is an occasion for everything,and a time for every activity under heaven:

I said to myself, “God will judge the righteous and the wicked, since there is a time for every activity and every work.”

But better than either of them is the one who has not yet existed, who has not seen the evil activity that is done under the sun.

For he does not think much about the fleeting days of his life because God keeps him preoccupied with the joy he derives from his activity.

For every activity there is a right time and procedure, even though man’s troubles are heavy on him.

When I applied my mind to know wisdom and to observe the activity that is done on the earth (even though one’s eyes do not close in sleep day or night),

I saw all of it as the activity of God. Frankly, a human being cannot understand what happens on earth, because however hard a man works to discover it, he will not find out. Despite what he thinks he knows, he will not be able to figure it out.

Whatever the activity in which you engage, do it with all your ability, because there is no work, no planning, no learning, and no wisdom in the next world where you're going.

Sow your seed in the morning, and do not stop working until the evening; for you do not know which activity will succeed -- whether this one or that one, or whether both will prosper equally.
