What May be Known (Romans 1:19-20)

1. What discoveries they had: That which may be known of God is manifest, en autois—among them; that is, there were some even among them that had the knowledge of God, were convinced of the existence of one supreme Numen. The philosophy of Pythagoras, Plato, and the Stoics, discovered a great deal of the knowledge of God, as appears by abundance of testimonies. That which may be known, which implies that there is a great deal which may not be known. The being of God may be apprehended, but cannot be comprehended. We cannot by searching find him out, Job 11:7-9. Finite understandings cannot perfectly know an infinite being; but, blessed be God, there is that which may be known, enough to lead us to our chief end, the glorifying and enjoying of him; and these things revealed belong to us and to our children, while secret things are not to be pried into, Deu. 29:29.

2. Whence they had these discoveries: God hath shown it to them. Those common natural notions which they had of God were imprinted upon their hearts by the God of nature himself, who is the Father of lights. This sense of a Deity, and a regard to that Deity, are so connate with the human nature that some think we are to distinguish men from brutes by these rather than by reason.

3. By what way and means these discoveries and notices which they had were confirmed and improved, namely, by the work of creation (v. 20); For the invisible things of God, etc.

(1.) Observe what they knew: The invisible things of him, even his eternal power and Godhead. Though God be not the object of sense, yet he hath discovered and made known himself by those things that are sensible. The power and Godhead of God are invisible things, and yet are clearly seen in their products. He works in secret (Job 23:8, 9; Ps. 139:15; Eccl. 11:5), but manifests what he has wrought, and therein makes known his power and Godhead, and others of his attributes which natural light apprehends in the idea of a God. They could not come by natural light to the knowledge of the three persons in the Godhead (though some fancy they have found footsteps of this in Plato's writings), but they did come to the knowledge of the Godhead, at least so much knowledge as was sufficient to have kept them from idolatry. This was that truth which they held in unrighteousness.

(2.) How they knew it: By the things that are made, which could not make themselves, nor fall into such an exact order and harmony by any casual hits; and therefore must have been produced by some first cause or intelligent agent, which first cause could be no other than an eternal powerful God. See Ps. 19:1; Isa. 40:26; Acts 17:24. The workman is known by his work. The variety, multitude, order, beauty, harmony, different nature, and excellent contrivance, of the things that are made, the direction of them to certain ends, and the concurrence of all the parts to the good and beauty of the whole, do abundantly prove a Creator and his eternal power and Godhead. Thus did the light shine in the darkness. And this from the creation of the world. Understand it either, [1.] As the topic from which the knowledge of them is drawn. To evince this truth, we have recourse to the great work of creation. And some think this ktisis kosmou, this creature of the world (as it may be read), is to be understood of man, the ktisis katÕ exocheµn—the most remarkable creature of the lower world, called ktisis, Mk. 16:15. The frame and structure of human bodies, and especially the most excellent powers, faculties, and capacities of human souls, do abundantly prove that there is a Creator, and that he is God. Or, [2.] As the date of the discovery. It as old as the creation of the world. In this sense apo ktiseoµs is most frequently used in scripture. These notices concerning God are not any modern discoveries, hit upon of late, but ancient truths, which were from the beginning. The way of the acknowledgement of God is a good old way; it was from the beginning. Truth got the start of error.
