Sir John Herschel, the most profound philosopher in the science of astronomy the world has ever known; one whose inventions and improvements in the telescope have far surpassed those of all others; one who has enjoyed the highest advantages in the study and demonstration of the science, and who has made most important discoveries in regard to the sun, and moon, and the planets--and even the fixed stars, or suns, in the far off sidereal regions--tells us that from his investigations and discoveries in regard to the Sun, there appears to be _a vast globe within_ the surrounding _photosphere of fire_, shielded by a void or non-luminous atmosphere, thus apparently protecting it from the surrounding flame of fire, and rendering it possible that the vast globe within is susceptible of animated life, which may exist there in some form. This, with the general corroboration of other astronomers, as to the two encircling volumes of atmosphere--the outer a luminous, and the inner a non-luminous one--is strong evidence confirmative of our hypothesis of the existence of that immense inner globe, or world, which is doubtless in reality the _Heavenly world_; the Saviour's empire, and the abode of the righteous. Methinks, had Sir John Herschel but turned his attention for awhile to the flood-lights of Divine Revelations, made by God himself through His Spirit to fallen man, he would ere this have opened the "gate" to the eye of faith, and bid the weary Christian to look and behold the confines of that bright world which was opened, and flashed its inner light upon the eyes of the dying martyr Stephen, when, "Being full of the Holy Ghost, he looked up steadfastly into heaven, and saw the glory of God, and Jesus standing at the right hand of God, and said, Behold, I see heaven opened." Thus, we are led to the inevitable conclusion that heaven is not so far distant but that it can be seen from earth by the _spirit-eye_, if God shall but open, and disclose it to view. Where else can we imagine its location, to be within range of--even immortal--vision from this earth? St. John, while in the spirit, had a view of that heavenly world, and the vast city with glittering jasper walls, and gold-paved streets, and even the "great white throne," the Saviour on that throne, surrounded by an innumerable company that no man can number. St. Paul, in spirit, was caught up, even into the "third heaven," and "saw and heard things which it were not lawful for man to utter" to mortals on earth. He tells us that "eye hath not seen, neither ear hath heard, nor hath it entered the heart of man, the glory that shall be revealed." But we will not here anticipate the still stronger evidence we have yet to lay before the mind as we pursue this interesting theme.
