This tendency of heat upward, or away from the base of the fire, is plainly evident by the fact that heat will not penetrate to any considerable depth _downward_, neither when on the earth, or on a solid non-combustible foundation; nor yet when on an elevated platform, for its tendency, as we have shown, is always outward or upward. So also with the fires of the _Sun_; whatever the base of its fires may be, we see by the fixed laws of Nature that the tendency of its heat is _outward_, no matter from what portion of that base it may emanate. We cannot now comprehend the _nature_ of the base of the Sun's fires, but we know that the great Jehovah has provided it, and that it is founded in His wisdom, and is fixed and sure, and we have reasoned conclusively that it cannot be of combustible material. Hence, the only rational conclusion we can arrive at--from a thorough investigation of Divine revelations; from all the lights afforded by the science of astronomy; from the true philosophy of Nature, as well as from all that is visible and perceptible--is, that far within the circling photosphere of ethereal fire which we see and realize as the _Sun_, there is a solid body, a globe, a VAST WORLD, and that world is the heaven for all the righteous from this earth; that it is the Saviour's allotted empire, and that He is there the ruler of His people. _THE NATURE OF THE LIGHT OF THE HEAVENLY WORLD._ "_The glory of God doth lighten it, and the Lamb is the light thereof._" We have given the above Scripture quotation repeatedly in these pages, in order to forcibly impress the minds of all with the fact that the light of the heavenly world is _different_ from the light of the Sun; that it far transcends it in _brightness_. For we are told that it "is far above the brightness of the Sun shining in its strength," even "_seven-fold brighter than the Sun_." Let us contemplate what has been revealed of this "glory light." First. No _mortal_ ever has beheld the full radiance of the face, or glory of God. For He hath said that no one should see His face and live. In evidence of this, when Moses, who was so near Him, and desired so much to behold His face unveiled, prayed to Him saying: "I _beseech thee_, show me thy glory." There came an answer unto him. "_Thou canst not see my face, for there shall no man see me and live._" And in order to preserve the life of Moses, God placed him in the "cleft of a rock" and covered him with His hand while His glory was passing by. Others have desired to see God, and the brightness of His glory, yet such desire, while in mortality, is wrong, for none could behold it and live.
