'Works of God' in the Bible

He has made everything right in its time; but he has made their hearts without knowledge, so that man is unable to see the works of God, from the first to the last.

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.

As thou knowest not what is the way of the spirit, nor how the bones do grow in the womb of her that is with child: even so thou knowest not the works of God who maketh all.
