20 For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse: (Romans 1:20 KJV)
William Burkitt’s Commentary
The apostle here proceeds in acquainting us with that knowledge of God which the Heathens had by the light of nature, which was in their hearts, and augmented and increased by what of God they saw in the book of the creatures; namely, in the works of creation and providence: The invisible things of God from the creation of the world are clearly seen, &c. The sense, I conceive, is this, That the wise and wonderful frame of the world, which cannot reasonably be ascribed to any other cause but God, is a sensible demonstration to all mankind of an eternal and powerful Being who was the author and contriver of it. The strokes of the Creator’s hand are engraved in all parts of the universe; the heavens, the earth, and the capacious sea, with all things contained in them, are evident testimonies of the excellency of their original cause: And therefore those Heathens of old who shut their eyes and those Atheists of this day who wink hard and will not see the footsteps of a Deity in the works of creation and providence, are, and will be, everlastingly left without excuse.
Learn hence, 1. That much of the being and essential perfections of God may be known by the light of nature if attended to, and much more may be understood by the book of the creatures, if attentively looked into. The invisible things of God are clearly seen from the creation; that is, the creation of the world is a plain demonstration to men of the being and power of God.
Learn, 2. That all such persons will be left forever without excuse before God, who either extinguish the light of nature, and smother the natural notices which they have of God, or do not improve them by a due consideration of the works of God. Without opening the eye of reasons, the book of creation is of no more use to us than to the brute beasts: They see the creatures as well as we, but many of us consider the creatures and see God in the creation no more than they: And this will leave us without excuse.
Learn, 3. How endearing are our obligations to Almighty God for the favour and benefit of divine revelation; that, together with the light of nature, we have the superadded light of scripture; the law to convince us of our sin, the gospel to discover a Saviour. The Heathens had only those natural apostles, of sun, moon, and stars, to guide them to the wisdom of the Father, the incarnate Son of God, and his inspired apostles and ministers to lead us into all truth, and his Holy Spirit to excite and quicken us in our obedience to him.
Therefore, eternally magnified be Omnipotent Love for the light of scripture and the benefit of divine revelation. For though there be a natural theology, there is not a natural Christology; there is a natural divinity, but not a natural gospel, a knowledge of God by the light of nature, but no knowledge of Jesus the Mediator, without the light of scripture.
All thanks, eternal thanks be to God for his unspeakable gift! Lord, how will all such as contemn it be left without excuse!
