6 Bible Verses about Unknown Future

For no one knows what will happen;
So who can tell him how and when it will happen?

For who [limited by human wisdom] knows what is good for man during his lifetime, during the few days of his futile life? He spends them like a shadow [staying busy, but achieving nothing of lasting value]. For who can tell a man what will happen after him [to his work, his treasure, his plans] under the sun [after his life is over]?

Yet the fool multiplies words, though no man knows what will happen, and who can tell him what will come after he is gone?

So I have seen that there is nothing better than that a man should be happy in his own works and activities, for that is his portion (share). For who will bring him [back] to see what will happen after he is gone?

In the day of prosperity be joyful,
But in the day of adversity consider that
God has made the one as well as the other,
So that man will not find out anything that will be after him.

There is no remembrance of earlier things,
Nor also of the later things that are to come;
There will be for them no remembrance
By generations who will come after them.
