Concise Bible Dictionary:

God was early revealed in fire. The searching character of His righteous judgment was thus set forth, whether in the acceptance of good or the condemnation of evil. When Moses at Horeb approached the burning bush he was cautioned not to draw near, but to remove his shoes, for the ground was holy. God spake to him out of the burning bush (Ex. 3:1-61Now Moses kept the flock of Jethro his father in law, the priest of Midian: and he led the flock to the backside of the desert, and came to the mountain of God, even to Horeb. 2And the angel of the Lord appeared unto him in a flame of fire out of the midst of a bush: and he looked, and, behold, the bush burned with fire, and the bush was not consumed. 3And Moses said, I will now turn aside, and see this great sight, why the bush is not burnt. 4And when the Lord saw that he turned aside to see, God called unto him out of the midst of the bush, and said, Moses, Moses. And he said, Here am I. 5And he said, Draw not nigh hither: put off thy shoes from off thy feet, for the place whereon thou standest is holy ground. 6Moreover he said, I am the God of thy father, the God of Abraham, the God of Isaac, and the God of Jacob. And Moses hid his face; for he was afraid to look upon God. (Exodus 3:1‑6)). On Mount Sinai "the sight of the glory of the. Lord was like devouring fire" (Gen. 24:1717And the servant ran to meet her, and said, Let me, I pray thee, drink a little water of thy pitcher. (Genesis 24:17)). Moses declared to Israel, "The Lord thy God is a consuming fire" (Deut. 4:2424For the Lord thy God is a consuming fire, even a jealous God. (Deuteronomy 4:24)). When Aaron began his ministrations in the tabernacle fire came out "from before the Lord, and consumed upon the altar the burnt offering and the fat" (Lev. 9:2424And there came a fire out from before the Lord, and consumed upon the altar the burnt offering and the fat: which when all the people saw, they shouted, and fell on their faces. (Leviticus 9:24): Compare 1 Kings 18:3838Then the fire of the Lord fell, and consumed the burnt sacrifice, and the wood, and the stones, and the dust, and licked up the water that was in the trench. (1 Kings 18:38); 1 Chron. 21:2626And David built there an altar unto the Lord, and offered burnt offerings and peace offerings, and called upon the Lord; and he answered him from heaven by fire upon the altar of burnt offering. (1 Chronicles 21:26); 2 Chron. 7:1-31Now when Solomon had made an end of praying, the fire came down from heaven, and consumed the burnt offering and the sacrifices; and the glory of the Lord filled the house. 2And the priests could not enter into the house of the Lord, because the glory of the Lord had filled the Lord's house. 3And when all the children of Israel saw how the fire came down, and the glory of the Lord upon the house, they bowed themselves with their faces to the ground upon the pavement, and worshipped, and praised the Lord, saying, For he is good; for his mercy endureth for ever. (2 Chronicles 7:1‑3)). Nadab and Abihu offered “strange fire,” and fire went out from the Lord and consumed them (Lev. 10:1-21And Nadab and Abihu, the sons of Aaron, took either of them his censer, and put fire therein, and put incense thereon, and offered strange fire before the Lord, which he commanded them not. 2And there went out fire from the Lord, and devoured them, and they died before the Lord. (Leviticus 10:1‑2)). Thus God manifested Himself in fire to Moses. He showed His acceptance of the sacrifices by fire from heaven; He vindicated His servant Elijah, when he stood alone against the prophets of Baal, by consuming the sacrifice, the wood and the stone, by fire from heaven (1 Kings 18:3838Then the fire of the Lord fell, and consumed the burnt sacrifice, and the wood, and the stones, and the dust, and licked up the water that was in the trench. (1 Kings 18:38)); and He vindicated His own honor by fire, by destroying those who were disobedient in approaching to Him. The general idea in “fire” is that of judgment.
In the N. T. it is repeated, "Our God is a consuming fire" (Heb. 12:2929For our God is a consuming fire. (Hebrews 12:29)), to consume the dross in the Christian, as gold is tried and purified in the fire; and to judge and punish the wicked with unquenchable fire; who are also described as being Baptized WITH FIRE (Matt. 3:11-1211I indeed baptize you with water unto repentance: but he that cometh after me is mightier than I, whose shoes I am not worthy to bear: he shall baptize you with the Holy Ghost, and with fire: 12Whose fan is in his hand, and he will throughly purge his floor, and gather his wheat into the garner; but he will burn up the chaff with unquenchable fire. (Matthew 3:11‑12)). One of the most awful things connected with this word is the description of the place of eternal punishment as THE LAKE OF FIRE (Rev. 19:2020And the beast was taken, and with him the false prophet that wrought miracles before him, with which he deceived them that had received the mark of the beast, and them that worshipped his image. These both were cast alive into a lake of fire burning with brimstone. (Revelation 19:20); Rev. 20:10, 14-1510And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet are, and shall be tormented day and night for ever and ever. (Revelation 20:10)
14And death and hell were cast into the lake of fire. This is the second death. 15And whosoever was not found written in the book of life was cast into the lake of fire. (Revelation 20:14‑15)). What mercy to be delivered therefrom!
