Ps 90:2 Before the mountains were brought forth, or ever thou hadst formed the earth and the world, even from everlasting to everlasting, thou art God.
Heb 12:29 For our God is a consuming fire.
The everlasting fire is God. The Truth of God, as a fire, consumes all that is false. The Life of God consumes death, as a fire. The
Love of God consumes hatred, as a fire. The Light of God devours darkness, as a fire. Thus spake the King Messiah:
Lu 12:49 I am come to send fire on the earth; and what will I, if it be already kindled?
That is, Messiah came to send the WORD OF TRUTH into the earth; and the kindling of the truth; which in its perfection devours all that is not true; all that is false is given over to the power of the flame.
1Cor 3:13 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. If any man’s work abide which he hath built thereupon, he shall receive a reward. If any man’s work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire.
Thus gehenna is analogically an EVENT occurring at "the day" which day is none else but the day of the LORD
Mal 4:1 For, behold, the day cometh, that shall burn as an oven; and all the proud, yea, and all that do wickedly, shall be stubble: and the day that cometh shall burn them up, saith the LORD of hosts, that it shall leave them neither root nor branch.
at the time of the parousia, the mystery is finished:
Re 10:7 But in the days of the voice of the seventh angel, when he shall begin to sound, the mystery of God should be finished, as he hath declared to his servants the prophets.
At the parousia of the Lord, all that is not of God will perish. All that is not of God will be consumed by the flame. That is to say, all ignorance will perish; all hatred will perish; all unbelief will perish; all that is undesirable must perish in the fire; this is the destruction of confusion, and the perfection of the creation.
Ga 4:3 Even so we, when we were children, were in bondage under the STOICEIA of the world:
Ga 4:9 But now, after that ye have known God, or rather are known of God, how turn ye again to the weak and beggarly STOICEIA, whereunto ye desire again to be in bondage?
Col 2:8 Beware lest any man spoil you through philosophy and vain deceit, after the tradition of men, after the STOICEIA of the world, and not after Christ.
Col 2:20 Wherefore if ye be dead with Christ from the STOICEIA of the world, why, as though living in the world, are ye subject to ordinances,
2Pe 3:10 But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the STOICEIA shall melt with fervent heat, the earth also and the works that are therein shall be burned up.
2Pe 3:12 Looking for and hasting unto the coming of the day of God, wherein the heavens being on fire shall be dissolved, and the STOICEIA shall melt with fervent heat?
Thus these ELEMENTS/STOICEIA are the vain philosophies and traditions of men. The churches of Christ have become far too polluted by the traditions of men; the preachers do not seek the Lord but only blindly follow the doctrines handed down to them- which appear to be true but are in fact, misunderstanding and misrepresentation of the Truth of God. These vain traditions and interpretations, philosophies and doctrines are that which are burned away when the Truth of God is revealed. This flame, this TRUTH, destroys and devours all that is false, all that is death, all that is ignorance; and all things are made new; for this is the beginning of the NEW CREATION, as the apostle has written:
2Cor 5:17 Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new. And all things are of God, who hath reconciled us to himself by Jesus Christ, and hath given to us the ministry of reconciliation; To wit, that God was in Christ, reconciling the world unto himself, not imputing their trespasses unto them; and hath committed unto us the word of reconciliation.
Re 21:5 And he that sat upon the throne said, Behold, I make all things new. And he said unto me, Write: for these words are true and faithful.
So at the parousia (that is to say, the second coming/advent), the truth is revealed to all flesh, and this truth consumes all lies- this is the destruction of the unbelievers, who will then have become believers, as the truth will be revealed, as a fire; and thus there will be found no unbeliever again forever, and they are consumed from off the face of the earth in a moment. All things become new.
Jer 5:14 Wherefore thus saith the LORD God of hosts, Because ye speak this word, behold, I will make my words in thy mouth fire, and this people wood, and it shall devour them.
Rev 11:5 And if any man will hurt them, fire proceedeth out of their mouth, and devoureth their enemies: and if any man will hurt them, he must in this manner be killed.
Jer 23:29 Is not my word like as a fire? saith the LORD; and like a hammer that breaketh the rock in pieces?
In the coming judgment of the churches of Christ, those who receive the mark of the beast, and which forsake Christ in their confusion, and turn to the side after Baal; these will be given to the flame; and for these which foresake Christ, the truth revealed through Christ at the parousia will be as fire, and they will weep and gnash their teeth, knowing they have forsaken the Christ, and lost their crown:
Ez 16:32 But as a wife that committeth adultery, which taketh strangers instead of her husband!
Ho 10:8 The high places also of Aven, the sin of Israel, shall be destroyed: the thorn and the thistle shall come up on their altars; and they shall say to the mountains, Cover us; and to the hills, Fall on us.
Mt 13:41 The Son of man shall send forth his angels, and they shall gather out of his kingdom all things that offend, and them which do iniquity; And shall cast them into a furnace of fire: there shall be wailing and gnashing of teeth.
Mt 25:30 And cast ye the unprofitable servant into outer darkness: there shall be weeping and gnashing of teeth.
Lu 13:28 There shall be weeping and gnashing of teeth, when ye shall see Abraham, and Isaac, and Jacob, and all the prophets, in the kingdom of God, and you yourselves thrust out.
