From an eloquent passage in his sermon on the text (1 John i. 5,) “God is light,” it will likewise be seen that if Binning spoke, like a philosopher, of the properties of light, his was the language of a Christian philosopher—“The light is, as it were, a visible appearance of the invisible God. He hath covered his invisible nature with this glorious garment, to make himself in a manner visible to man. It is true, that light is but, as it were, a shadow of that inaccessible light, _umbra Dei_. It is the dark shadow of God, who is himself infinitely more beautiful and glorious. But yet, as to us, it hath greater glory and majesty in it, than any creature besides. It is the chief of the works of God, without which the world would be without form and void. It is the very beauty of the creation, that which gives lustre and amiableness to all that is in it, without which the pleasantest paradise would become a wilderness, and this beautiful structure, and adorned palace of the world, a loathsome dungeon. Besides the admirable beauty of it, it hath a wonderful swift conveyance throughout the whole world, the upper and lower, in a moment, in the twinkling of an eye. It is carried from the one end of heaven to the other in a moment, and who can say by what way the light is parted? Job xxxviii. 24. Moreover, it carries alongst with it a beautiful influence, and a refreshing heat and warmness, which is the very life and subsistence of all the creatures below. And so, as there is nothing so beautiful, so nothing so universally and highly profitable. And to all this, add that singular property of it, that it is not capable of infection, it is of such absolute purity, that it can communicate itself to the dunghill, as well as to the garden, without receiving any mixture from it. In all the impurities it meets withal, it remains unmixed and untainted, and preserves its own nature entire. Now you may perceive, that there is nothing visible that is fitter to resemble the invisible God, than this glorious, beautiful, pure, and universally communicable creature, light.… “Then add unto this, to make up the resemblance fuller, the bounty and benignity of his influence upon the world, the flowings forth of his infinite goodness, that enrich the whole earth. Look, as the sun is the greatest and most universal benefactor,—his influence and heat is the very renovation of the world. It makes all new, and green, and flourishing; it puts a youth upon the world, and so is the very spring and fountain of life to all sublunary things. How much is that true of the true light, of the substantial, of whom this sun is but a shadow!…
