6 Bible Verses about Unknown Future

For who knoweth what is good for man living, in the days of his vain life, which is but a shadow? Or, who will tell a man what shall happen after him under the Sun?

A fool is so full of words, that a man cannot tell what end he shall make. Who will then warn him of it that shall follow after him?

Wherefore I perceive, that there is nothing better for a man, than to be joyful in his labour, for that is his portion. But who will bring him to see the thing that shall come after him?

Use well the time of prosperity and remember the time of misfortune: For God maketh one by the other, so that a man can find nothing else.

The thing that is past, is out of remembrance; Even so the things that are for to come, shall no more be thought upon among them that come after.
