The Scriptures teach that God has never learned from anyone. “Who hath directed the Spirit of the Lord, or being his counsellor hath taught him? With whom took he counsel, and who instructed him, and taught him in the path of judgment, and taught him knowledge, and shewed to Him the way of understanding?”
”For who hath known the mind of the Lord? or who hath been His counsellor?” These rhetorical questions put by the prophet and the apostle Paul declare that God has never learned.
From there it is only a step to the conclusion that God cannot learn. Could God at any time or in any manner receive into His mind knowledge that He did not possess and had not possessed from eternity, He would be imperfect and less than himself. To think of a God who must sit at the feet of a teacher, even though that teacher be an archangel or a seraph, is to think of someone other than the Most High God, maker of heaven and earth.
This negative approach to the divine omniscience is, I believe, quite justified in the circumstances. Since our intellectual knowledge of God is so small and obscure, we can sometimes gain considerable advantage in our struggle to understand what God is like by the simple expedient of thinking what He is not like. So far in this examination of the attributes of God we have been driven to the free use of negatives. We have seen that God had no origin, that He had no beginning, that He requires no helpers, that He suffers no change, and that in His essential being there are no limitations.
This method of trying to make men see what God is like by showing them what He is not like is used also by the inspired writers in the Holy Scriptures. “Hast thou not known? hast thou not heard,” cries Isaiah, “that the everlasting God, the Lord, the Creator of the ends of the earth, fainteth not, neither is weary?” And that abrupt statement by God Himself, “I am the Lord, I change not,” tells us more about the divine omniscience than could be told in a ten-thousand word treatise, were all negatives arbitrarily ruled out. God’s eternal truthfulness is stated negatively by the apostle Paul, “God… cannot lie”; and when the angel asserted that “with God nothing shall be impossible,” the two negatives add up to a ringing positive.
That God is omniscient is not only taught in the Scriptures, it must be inferred also from all else that is taught concerning Him. God perfectly knows Himself and, being the source and author of all things, it follows that He knows all that can be known. And this He knows instantly and with a fullness of perfection that includes every possible item of knowledge concerning everything that exists or could have existed anywhere in the universe at any time in the past or that may exist in the centuries or ages yet unborn.
