6 Bible Verses about Unknown Future

For he knows not that which shall be: for who can tell him when it shall be?

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

A fool also is full of words: a man cannot tell what shall be; and what shall be after him, who can tell him?

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

In the day of prosperity be joyful, but in the day of adversity consider: God also has set the one over against the other, to the end that man should find nothing that will come after him.

There is no remembrance of former things; neither shall there be any remembrance of things that are to come with those that shall come after.
