In order to bring all home to your own reason and comprehension, let us ask, Where else is it feasible for so large a place to _be_ whereon, or into which the _Sun_, or _suns_, do not or _cannot shine_? We have shown you that suns (the surrounding volumes of photospheric ethereal fire) are--so far as we can comprehend--the natural sources of light throughout the Universe of Jehovah's empire. They seem as God's own _eternal lamps_, scattered and placed at His will in different regions of illimitable space, to illumine the universe without, and give _light everywhere_, as also life and animation to all their surrounding worlds. Each perhaps to its own, even as our Sun does to its own planet-worlds. Now when we consider that the fact is well established by all leading Astronomers that this outside flame or volume of fire is _far out_ from that INNER GLOBE, or world, and that between them _there is a void_, possibly thousands of miles in depth; that the fires and light of the _Sun_ have no perceptible effect upon this non-luminous void--and, indeed, the void shields the globe within from the light and heat of the Sun--we can readily imagine the wise arrangement of the Great Architect, and also comprehend the truth of His own declarations, that heaven is a place where neither the Sun nor its heat shall light upon its inhabitants. Now the nature of the _element_ of this intervening void or space, whether _it_ is _ethereal_ or not, we cannot now comprehend. That it is a safe covering or shield to the world within, we can readily suppose. For Sir John Herschel says that it seems as "an awning or screen, protecting the body," or world within, from the Sun's heat. But we are not left to conjecture alone, without philosophical reason in this matter. We know the laws of gravitation and attraction are fixed and sure, and upon these universal laws we can base correct conclusions. The tendency of fire or heat is _outward_ and _upward_. The sense in which we use the term "upward" is that of space far out from the earth, or like solid bodies. We have shown, in our explanation of the law of gravitation, that _upward_ is simply away from the earth. Thus, we ignite material with fire and produce combustion here, and we see the flame _rise_, and feel and know the heat ascends _upward_. So also may the Chinaman do the same, at the same moment, on the opposite side of the globe--while his position is directly under us, as we construe downward--and yet the flame and heat of his fire ascends _upward_ from the earth where he stands, which is in a directly opposite direction from the course ours pursues. Thus, to us, outward from the earth is _upward_, no matter where our position on it.
