God has made everything fit beautifully in its appropriate time, but he has also placed ignorance in the human heart so that people cannot discover what God has ordained, from the beginning to the end of their lives.

I have discovered only this: God made human beings for righteousness, but they seek many alternatives."

Just as no human being has control over the wind to restrain it, so also no human being has control over the day of his death. Just as no one is discharged during war, so wickedness will not release those who practice it.

In addition, no human being knows his time: Like fish captured in a cruel net, or as birds caught in a snare, so also are human beings caught by bad timing that surprises them.

And I set my mind to seek and explore by [man’s] wisdom all [human activity] that has been done under heaven. It is a miserable business and a burdensome task which God has given the sons of men with which to be busy and distressed.

For no one knows [whether] the spirit of a human ascends [to heaven] and [whether] the spirit of the beast descends to the ground!

When a sentence is not executed at once against a crime, the human heart is encouraged to do evil.

then I discerned all that God has done: No one really comprehends what happens on earth. Despite all human efforts to discover it, no one can ever grasp it. Even if a wise person claimed that he understood, he would not really comprehend it.

Whatever has happened is beyond human understanding; it is far deeper than anyone can fathom.
