'Works of God' in the Bible

I understood of all the works of God, that it is not possible for a man, to attain unto works that are done under the Sun: and though he bestow his labour to seek them out, yet can he not reach unto them: yea, though a wise man would undertake to know them, yet might he not find them.

Now, like as thou knowest not the way of the wind, nor how the bones are filled in a mother's womb: Even so thou knowest not the works of God, which is the workmaster of all.
