“Fire” From 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. 3:1-6). On Mount Sinai "the sight of the glory of the. Lord was like devouring fire" (Gen. 24:17). Moses declared to Israel, "The Lord thy God is a consuming fire" (Deut. 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. 9:24: Compare 1 Kings 18:38; 1 Chron. 21:26; 2 Chron. 7:1-3). Nadab and Abihu offered “strange fire,” and fire went out from the Lord and consumed them (Lev. 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 18:38); 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. 12:29), 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. 3:11-12). 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. 19:20; Rev. 20:10, 14-15). What mercy to be delivered therefrom!
“Light” From Concise Bible Dictionary:
Besides the references to physical light as existing distinct from the sun, and then emanating from the sun as the great light-bearer, the term is mainly used in scripture in a moral sense. Light from God is His word revealing Himself, and not only making manifest the dangers here, but acting as a lamp in showing the true path (Psa. 119:105). The Psalmist asked Jehovah to lift upon him the light of His countenance (Psa. 4:6), and declared that Jehovah Himself was his light (Psa. 27:1). As natural light brings vigor and health to the body, so the light of God gives cheerfulness and strength to the soul.
“God is light,” and the Lord Jesus came to the earth as the true light which lighteth every man. He not only exposed all the evil in the world and all the false pretensions of the leaders of Israel; but “the life was the light of men” (John 1:4; John 8:12). Christians are “light in the Lord,” and are exhorted to walk as “children of light” (Eph. 5:8; 1 Thess. 5:5). In the midst of darkness they are set to shine as lights in the world (Phil. 2:15). A grave responsibility rests upon them lest they should not have the heavenly luster that would characterize them as having in their hearts the light of the glory of the Lord. If the light in the Christian become darkness by his not walking in the reality of it, how great is that darkness! (Matt. 6:23).
It has been very properly said that light is appropriately descriptive of God; for light, invisible in itself, manifests everything. Christians, as we have seen, are “light in the Lord,” and thus convict the unfruitful works of darkness; but here we may notice that it is not said of them, as of God, that they are “love,” for love is the sovereign, spring of activity in God.
