'Work of God' in the Bible

Consider the work of God. For who is able to make straight what he made crooked?

Then I saw all the work of God--man [is] not able to discover the work that is done under the sun. Although man may toil in seeking, he cannot find it. Even if a wise man claims [that he] knows it, he cannot find it.

Just as you do not know how the path of the wind [goes], nor how the bones [of a fetus] form in a mother's womb, so you do not know the work of God who makes everything.
