Job 38:36

Who hath put wisdom in the inward parts? or who hath given understanding to the heart?

Who has put wisdom in the inward parts and given understanding to the heart is God Himself, so that all human wisdom and understanding are received as gifts from Him. Man took no part in creating the world or anything that has the breath of life, for man was made last, after everything else had been formed. For this reason the chapter stands against human fallacies and holds fast the truth that man was created in the image of God and of Christ. It consists of God's own questions concerning mysteries revealed in nature, mysteries which even persons of the greatest intellect and the most profound scholarship cannot understand or answer.

Those questions were not given to be answered, but to call attention to the deep mysteries of God and to teach that human wisdom is limited. Even in the surroundings of daily life there are many things beyond the comprehension of finite beings. God has placed such mysteries in both divine revelation and in nature in order to command faith. He is to be acknowledged as much from what He does not reveal of Himself as from what is open to limited comprehension, for an infinity remains beyond all ever searching, inquiring, and learning.
