'Work of God' in the Bible

Consider the work of God:Who can make straight what He has bent?

and I saw all the work of God, I concluded that man cannot discover the work that is done under the sun. Even though man may labor in seeking, he will not discover; and [more than that], though a wise man thinks and claims he knows, he will not be able to find it out.

Just as you do not know the way and path of the wind or how the bones are formed in the womb of a pregnant woman, even so you do not know the activity of God who makes all things.
