Thanks to Pete Seeger and the Byrds, this is a famous passage of Ecclesiastes. And there are verses - phrases really - that have been taken out of this passage for children's songs and missionary conferences. But the main point of the passage is generally not taken into account.

But we need to take the main point of the passage seriously. God's Sovereignty over time, our inability to understand what God is doing, and the majesty of his timing and sovereignty are highlighted in the text to direct us to humility and joy and worship.
