6 Bible Verses about Unknown Future

For who knows what is good for man in life, all the days of his vain life which he spends like a shadow? For who can tell a man what will be after him under the sun?

A fool also multiplies words. Man doesn't know what will be; and that which will be after him, who can tell him?

Therefore I saw that there is nothing better, than that a man should rejoice in his works; for that is his portion: for who can bring him to see what will be after him?

In the day of prosperity be joyful, and in the day of adversity consider; yes, God has made the one side by side with the other, to the end that man should not find out anything after him.

There is no memory of the former; neither shall there be any memory of the latter that are to come, among those that shall come after.
