In our previous arguments, we have showed, conclusively, that the Sun is the source of fire, heat, and light. Let us now further examine the offices of this element thus derived from the _Sun_, and note in this investigation whether it is not, in some way, intimately connected with _heaven_. _First._ Under the Mosaic dispensation, God commanded His Prophets, and Priests, to build unto Him an Altar, and to offer sacrifices thereon; and such sacrifices would be accepted by Him, as should be evidenced by his sending down fire from heaven to consume the offerings. He also commanded, through Moses, that the fires should ever be burning upon the altar, and that the Priests should continue to renew sacrifices and burnt offerings upon it. These sacrifices were as memorials before the Lord, and typical of the coming of Christ, who should be the "great sacrifice," to ransom fallen man. Now it will be remembered that when such offerings were made, fire came down from heaven and consumed the offerings, and thus made manifest that the sacrifices were accepted of God. (Let it be remembered that we have shown, as far as finite mind can comprehend, that the _Sun_ is the only direct source of fire, and then remember that _fire came down from heaven_.) In the book of Job we read, "_The fire of God has fallen from heaven._" The Psalmist tells us that "God is a _Sun_ and a shield, who maketh His angels spirits, and His ministers a flaming fire." Now we know that angels are God's ministers, and how oft do we find recorded in the Bible, how--under the earlier dispensation--they appeared on earth in forms of _fire_, and with the brightness of the _Sun_. The Psalmist tells us again that: "Our God shall come, a fire shall devour before Him. A fire goeth before Him and burneth up His enemies." The prophet Jeremiah proclaims: "Wherefore, thus saith the Lord God of hosts, Behold, I will make my words in thy mouth fire." The Psalmist answers: "While I was musing the fire burned." Thus, how plain the revelations that _God's Spirit is fire_. Not necessarily manifested at all times, by the burning and consuming our mortal bodies--this only in His _wrath_--but by the purifying of our natures; "burning up the dross, and base desires," and thus fitting us for the enjoyment of heaven and happiness, for "He shall be as a refiner's fire, and the righteous are saved as by fire." Let us hear what the prophet Jeremiah saith: "For behold the Lord will come with fire; and with His chariots like a whirlwind, to render his anger with fury, and His rebukes with flames of fire, and the slain of the Lord shall be many." Ah, when He comes forth with His _Spirit of fire_ in _wrath_ and indignation, then it is that this element is one of terrible destruction. Comprehending this, the a same prophet inquires:
