1) God consumes what makes a person remain an unbeliever and makes them a believer by the things to which He purifies in our lives: free from sin, power over satan, and life eternal
Hebrews 12:29
29 For our God is a consuming fire.
2) God wants to speak to us through the fire.
Exodus 3:2
2 And 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.
3) God revealed that his fire is all about us even when our natural eyes cannot see it
2 Kings 6:17
17 And Elisha prayed, and said, Lord, I pray thee, open his eyes, that he may see. And the Lord opened the eyes of the young man; and he saw: and, behold, the mountain was full of horses and chariots of fire round about Elisha.
(To the servant there was need of a more manifest vision, and for this Elisha prays, and God vouchsafes to grant it, that the servant may become as confident as his master. It is not that the troops may be gathered that Elisha prays, they are there already, but that the servant may have a seeing eye bestowed upon him to discern how well he and his master are protected.)
4) God showed us to not be afraid of the fire when we take a stand by faith. For when the fire will destroy the enemy it will protect one whom serves God.
Daniel 3:25
25 He answered and said, Lo, I see four men loose, walking in the midst of the fire, and they have no hurt; and the form of the fourth is like the Son of God.
5) The fire of god will destroy every natural and carnal thing in us, like it or not.
1 Kings 18:38
38 Then 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.
6) The fire of God will show you exactly what you are and where your passion is
1 Corinthians 3:13
13 Every man’s work shall be made manifest: for the day shall declare it, because it shall be revealed by fire; and the fire shall try every man’s work of what sort it is.
7) God not only wants you to outwardly declare your salvation and freedom from sin by water; God wants to declare inwardly to yourself and to Satan that you are free and with that power you rebuke his attempts to destroy you.
Matthew 3:11
11 I 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:
8) The fire of God came to consume what would have made our tongues unworthy to speak in the Heavenly language (or in tongues). Now as we walk in the spirit we are able to speak to God literally and spiritually.
Acts 2:3
3 And there appeared unto them cloven tongues like as of fire, and it sat upon each of them.
9) God wanted us to rejoice because we have the assurance that if we are put in the fire in His name then we will not burn: not on earth nor in hell! Embrace the protecting fire
1 Peter 1:6-8
6 Wherein ye greatly rejoice, though now for a season, if need be, ye are in heaviness through manifold temptations:
7 That the trial of your faith, being much more precious than of gold that perisheth, though it be tried with fire, might be found unto praise and honour and glory at the appearing of Jesus Christ:
8 Whom having not seen, ye love; in whom, though now ye see him not, yet believing, ye rejoice with joy unspeakable and full of glory:
10) Without having Jesus Christ as your Savior you will fall victim to the consuming fire
Revelation 20:15
15 And whosoever was not found written in the book of life was cast into the lake of fire.
