As per Apostle peter..."those who in error walk , PROMISING FREEDOM"
In the past there were false prophets who, being part of "supposed believers", were accepted and looked up to as "righteous prophets" by the people and for the people.
Peter goes on to say that there will also be false teachers (leaders / fountains) in you (part of you / accepted by you). These people, who you will consider to be your leaders, will stealthily /unrecognizably advance and confess a "destructive way" (a heresy/ a dissension from the One Truth) which you will embrace and glorify as the true, right, and good way...but which (in itself) will deny the Truth & Preeminence of the Master who redeemed us, declaring that man's way is right and that the Way of God is not the right way... not the only way.
(...and in so doing, because of their love for this way of adultery / for knowing "good and evil" in their eyes, their/your destruction will be swift at Judgement.)
And many people, including "self-professing" christians, will follow, glorify, and stand for this way (of perdition), through which the One Way of the Truth will be spoken of as evil (as against "god", as extreme & unjust / as against freedom of equality and self-rights) and Christ, the Son of God, will be redefined to represent their belief in the way of freedom and equality of one's rights.
And through covetousness, through one's desire for and belief in self-interest/self-will, they will mould/ manipulate/ pervert the words of scripture to justify/glorify their way and they will make gain of you (will convince you)... and you will willingly receive and live by their way.
But the judgement of old is not idle for them and those that glorify this way, and their destruction slumbers not.
...For God, who spared not the angels who sinned - but having cast them to the deepest abyss in chains of darkness, keeps them so as to be delivered for judgement;
...And the ancient world He did not spare, but only the eight of Noe the righteous a herald preserved, and the flood upon world of ungodly He brought in;
...And cities of Sodom and Gomorrah, which He condemned to be overthrown and reduced to ashes, He set as an example to the wicked.
But righteous Lot, who was oppressed by those who rejected the Will of God and by those who instead embraced their self-serving will, was delivered by God (through seeing for and hearing, the righteous dwelling among them, day by day his righteous soul with lawless works tormented).
The Pious Lord knows how to deliver the righteous out of temptation (calamity/adversity), and to keep the unrighteous to be punished in the day of judgement;
...and specially those who despise the One Lordship and Master and who walk after the pollution of their self-will (free-will) desires.
These are daring (presumptuous / arrogant / self-righteous) and self-willed ...who mock and blaspheme the "glories/the Way of Truth" which they do not respect/ fear, whereas angels, in strength and power greater being, do not even bring against them (the self-willed), before the Lord, a railing (accusative) charge.
But these (self-willed), as natural irrational animals (born for capture and corruption)...
...speak evil and blaspheme that which they are ignorant of, (which in their corruption they shall utterly perish, being about to receive reward of unrighteousness);
...esteeming (leading/advancing) the indulgence in daily self-desire/self-interest (which is a fault and disgrace);
...luxuriating in their feasts (celebrations) of deceits with you, eyes having full of an adulteress, and that cease not from sin (the way of error)...alluring souls unestablished (unstable);
...they are cursed children having a heart exercised in craving (covetousness/ self gain/self interest/self-rights).
Having left the straight Way, they went astray having followed in the way of Balaam of Bosor, who loved the reward of unrighteousness (self-interest and self-will)...but who received reproof of "his own" wickedness, as the prophet came to madness... as a dumb beast of burden speaking in a man's voice.
These (believers in self-will/free-will) are "fountains" without water, being driven by stormy clouds, to whom the gloom of darkness for ever is kept.
For by speaking great swelling words of vanity(of pride in and admiration of "oneself"), they allure (entice) , by licentiousness (self-will/free-will/freedom) and the desires of "one-self", those who scarcely (the few who) escaped from those who in error walk , PROMISING THEM FREEDOM, not realizing that they themselves are bondmen of corruption (destruction)....for by whom anyone has been subdued, by him also he is held in bondage.
For if having escaped the pollutions of the world through the knowledge (accurate knowledge) of the One Lord and Savior Jesus Christ , but by these again having been entangled they are subdued , has become to them the last (state) worse than the first .
...Better for it were for them not to have known the One Way of Righteousness than, having known it, to have turned from the Holy Teaching which was delivered to them.
But has happened to them the word of the true proverb: dog having returned to his own vomit; and the cleaned sow to rolling in the place of mire.
Will come at the close of the days, mockers (deluders/deceivers) walking (living-doing-worshipping) according to one's self lusts(desires/ freedoms/ interests/ rights) , and saying "Where is the promise of His Coming" ...redefining, denying, and rejecting the Preeminence, Lordship, and Rulership of Jesus Christ as the One and Only True Way, as the One King and Son of the Only God...rejecting to serve the Will of the One Creator God and instead embracing, serving, and glorifying the belief in free will / self will / freedom of all religions (gods) / freedom of self-rights.
Christ said..."not my will but Yours be done", which Christ did in love for the One and Only Father and in love for those who overcome and follow Only Him, the One True Way.
