This is the beginning of a topical Bible study about fire. I have looked into all the Bible verses with the word fire on them and have also looked at the sources above for guidance on this topic. These can help you form ideas for what fire may mean symbolically. It is an important subject about Christ's character that is commonly overlooked.
Fire can illuminate, Fire has heat and Fire can melt filth and fuses into one body, which is the Church of Jesus Christ
The fire that Jesus would kindled is the fire of good works poured out as coal upon our enemies heads. (Matt. 5:38-48, Rom 12:20) This is the fire which will bring righteous judgment into this world. In the same context, Jesus spoke of praying for your enemies.
Now the Scriptures tell us that perfect love casts out fear. (1 John 4:18) This perfect love is a fire, usually not found in the political, religious, and economic powers of mankind. It is found only in Christ. And when this perfect love burns within a heart, it sets the captive free from the power of fear used by the lower forms, rudiments, principles, laws, customs, rituals, etc., which were made by men to "control" each other.
We have found natural ways to increase the temperature of our fires to melt down things which were once thought impossible to melt or change in form. So too, one day our Maker will melt the stony hearts of Adam and bring forth pure gold . . . Christ in us, the hope of glory. It just takes the right kind and amount of heat.
When mankind learns to leave vengeance to God, we just might be surprised to find that even God's vengeance, may be found to be a power to be used for the good of all mankind, and not for its destruction. There is a fire which will release all who dwell in lower natures, lower thoughts, lower visions and raise them up to where He, our Creator, becomes All in All. (1 Cor. 15:28) May more Christians rise and be seated in heavenly places wherein, it seems is nothing but fire. In Him, there is no shifting or turning. There is no change. He is the End. He is our End. And what is that? God is love! And He is truly the ALL-CONSUMING FIRE!! Hallelujah!!
Paul implores us to present our bodies a living sacrifice, holy and acceptable to God. We are to be consumed by Him and not be destroyed in the process. Our devotion, our zeal, our passion should be towards His purposes.
Fire is represented as the symbol of Jehovah's presence and the instrument of his power, in the way either of approval or of destruction. Ex 3:2; 14:19 etc. There could not be a better symbol for Jehovah than this of fire, it being immaterial, mysterious, but visible, warming, cheering, comforting, but also terrible and consuming. Parallel with this application of fire and with its symbolical meaning are to be noted the similar use for sacrificial purposes and the respect paid to it, or to the heavenly bodies as symbols of deity, which prevailed among so many nations of antiquity, and of which the traces are not even now extinct; e.g. the Sabean and Magian systems of worship. Isa 27:9 Fire for sacred purposes obtained elsewhere than from the altar was called "strange fire," and for the use of such Nadab and Abihu were punished with death by fire from God. Le 10:1,2; Nu 3:4; 26:61
Fire symbolizes the transforming energy of the Holy Spirit's actions. The prayer of the prophet Elijah, who "arose like fire" and whose "word burned like a torch," brought down fire from heaven on the sacrifice on Mount Carmel. This event was a "figure" of the fire of the Holy Spirit, who transforms what he touches.
John the Baptist proclaims Christ as the one who will baptize you with the Holy Spirit and with fire. Jesus will say of the Spirit: "I came to cast fire upon the earth." On the morning of Pentecost, Jesus Christ fills them with the Holy Spirit, which is the Spirit of God and or the Spirit of Jesus Himself. The spiritual symbolism of fire is one of the most expressive images of the Holy Spirit's actions.
