The New Testament writers gave their warning regarding false prophets and St. Peter was no exception. In 2 Peter 2, Peter held nothing back.
Peter also included false teachers in the same category as false prophets. Bringing their own doctrines into their teaching instead of the glorious Gospel of Jesus Christ. He said these false teachers sneak in teachings that were heresies, teachings that were destructive to the church. To the extent that they would go so far as to deny their Master who brought them to the earth! in doing so, they would bring swift destruction upon themselves and suffer a terrible end.
These false prophets and teachers would be filled with sensuality, and many would follow them because of the attraction to the heightened emotions and senses. Peter warned that in their greed, they would begin to bring false teachings and doctrines. These false prophets and teachers were condemned from long, long ago. Their destruction does not wait to be wakened at the judgement.
Peter gave examples of God's power and authority over those who do not fully worship Him. Even the angels were cast into hell for their sin. They were chained in darkness until the day of Judgement. In the ancient world, Noah was spared for being a herald of righteousness. He and seven others survived the flood while the entire ancient world suffered a swift destruction. Sodom and Gomorrah was leveled to ashes, condemned to extinction to become an example of the fate for the ungodly.
Lot, however, was greatly upset with the sensual nature of the wicked people of Sodom and Gomorrah. Daily he was tormented over their lawless ways. God knows how to rescue the godly and righteous from such trials, and how to keep the unrighteous under punishment until the day of Judgement. Especially, Peter said, those who indulge in the lust of their defiling passion and despising of authority.
These false teachers and prophets boldly and willingly march forward in their destruction having no fear as they blaspheme the righteous. Even the angels who are greater in power and might will not pronounce blasphemous judgement against them before God!
Peter said these false prophets are like "irrational animals," creatures of instinct who are born to be captured and slaughtered. They blaspheme others for matters which they are completely ignorant. Peter said that in their destruction of others, they will also be destroyed. They will suffer for their wrongdoing.
Peter said that they take great pleasure in their wrongdoing in the sight of others. He said that they are nothing more than "blots" and "blemishes," taking pleasure in their deceptions in your company.
He said that these false prophets and teachers have eyes full of adultery. They have an unsatisfied desire for sin, and entice the souls who are not yet steady in their faith of Jesus Christ. Their hearts are full of greed.
"Accursed children!" Peter exclaimed. They have forsaken the true path to salvation and have gone astray! They followed after the way of Balaam who loved the gain he got from his wrongdoing! Balaam was rebuked for his own transgression against God. A donkey was given a human voice to restrain the prophet's madness!
Peter compared these false prophets and teachers to waterless springs, mists that were driven by a storm. The gloom of the utter darkness of hell has already been reserved for these evil ones.
They speak loudly with their boasts of their folly. They are entice others by their sensual passions, those who are on the edge of escaping sin to gain salvation. They promise freedom, but yet they themselves are slaves to their own corruption.
Peter said that the state of their souls were worse after learning about Christ. Though they had escaped the defilements of the world through knowing their Lord and Savior Jesus Christ, they again became entangled in sin. It would have been better for them to have never known the way of righteousness than to turn away from it!
Peter said that the proverb was very true: "The dog returns to its own vomit, and the pig after washing itself returns to wallow in the mire."
As Christians, we should ask ourselves: Were we enticed by the boasting of sensual things? Were we leaning on the edge of the fence between heaven and hell, and chose the wrong side? Do we listen to any other doctrine than the Gospel of Jesus Christ? Do we follow after men who judge others, when even the angels of heaven tremble in fear at the thought of it? Are we enticed by their loud screaming of folly? Do we continue to follow their teachings after they met with their swift destruction? Do we roll in the dog's vomit after the death of the dog?
