6 Bible Verses about Unknown Future

For he does not know what will be and who can tell him how and when it will be?

Who knows what is good for man in this life? Are all the days of his vain life that he spends like a shadow? Who can tell a man what will happen after his existence under the sun?

A fool also is full of words. A man cannot predict what will be and what will be after him. Who can tell him?

I see there is nothing better than that a man should rejoice in his own works. That is his portion. Who will bring him to see what will happen after him?

In the day of prosperity be joyful, but in the day of adversity consider that God made one as well as the other, to the end that man should find nothing that comes after him.

There is no memory of former things. Those who follow will not remember those who are yet to come.
