Ecclesiastes 3:11
He has made everything beautiful in its time. He has also set eternity in their hearts, yet so that man can't find out the work that God has done from the beginning even to the end.

What Ecclesiastes 3:11 means
Ecclesiastes says God makes each thing beautiful in its own season and plants a sense of eternity in the human heart, while keeping the full shape of his work beyond anything a person can trace from beginning to end.
This line sits inside the famous "a time for everything" passage in chapter 3, just after the list of seasons: a time to be born and a time to die, a time to plant and a time to uproot. Having walked through those opposites, the Teacher steps back and draws the conclusion. Everything has its fitting moment, and God makes each thing beautiful in its own time. Yet the same God who orders the seasons has set something in us that reaches past them, a longing for what does not end, along with the ache of never seeing the whole.
Ecclesiastes belongs to Israel's wisdom writings, and its narrator tests every road to meaning: pleasure, work, wealth, learning. He keeps returning to one word, often translated "vanity" or "meaningless," which literally means vapor or breath. His world held no clear map of an afterlife, so this verse is bold. It names the human hunger for permanence without pretending to satisfy it.
The word behind "eternity" can mean the distant past, the far future, or the sweep of all time. The translation reaches for "eternity." Either way, the verse names the gap between what we long for and what we can know, and leaves it open.
