¹⁷ These are waterless springs and mists driven by a storm. For them the gloom of utter darkness has been reserved. ¹⁸ For, speaking loud boasts of folly, they entice by sensual passions of the flesh those who are barely escaping from those who live in error. ¹⁹ They promise them freedom, but they themselves are slaves of corruption. For whatever overcomes a person, to that he is enslaved. ²⁰ For if, after they have escaped the defilements of the world through the knowledge of our Lord and Savior Jesus Christ, they are again entangled in them and overcome, the last state has become worse for them than the first. ²¹ For it would have been better for them never to have known the way of righteousness than after knowing it to turn back from the holy commandment delivered to them. ²² What the true proverb says has happened to them: “The dog returns to its own vomit, and the sow, after washing herself, returns to wallow in the mire.” – 2 Peter 2:17-22 ESV

It seems readily apparent that Peter was influenced by the letter written by Jude or perhaps it was the other way around. Both men had strong opinions concerning false teachers and there are a number of noticeable similarities between the way they describe them. Jude wrote:

…these people blaspheme all that they do not understand, and they are destroyed by all that they, like unreasoning animals, understand instinctively. – Jude 10 ESV

And the same unflattering assessment is found in Peter’s letter.

But these, like irrational animals, creatures of instinct, born to be caught and destroyed, blaspheming about matters of which they are ignorant, will also be destroyed in their destruction… – 2 Peter 2:12 ESV

Both men used stories from the Old Testament to highlight the judgment awaiting these false teachers. Peter and Jude each included the judgment that came upon the angels who chose to join Satan in his failed coup attempt against God.

…the angels who did not stay within their own position of authority, but left their proper dwelling, he has kept in eternal chains under gloomy darkness until the judgment of the great day… – Jude 6 ESV

God did not spare angels when they sinned, but cast them into hell and committed them to chains of gloomy darkness to be kept until the judgment… – 2 Peter 2:4 ESV

Jude was unsparing in his criticism of these men, describing them as “hidden reefs…waterless clouds…fruitless trees…wild waves of the sea…wandering stars” (Jude 12-13 ESV). And Peter, while using a few less metaphors was equally as critical. He referred to them as “waterless springs and mists driven by a storm” (2 Peter 2:17 ESV). And both men declare the same fate for these deceptive and unreliable purveyors of falsehood. 

For them the gloom of utter darkness has been reserved. – 2 Peter 2:17 ESV

…for whom the gloom of utter darkness has been reserved forever. – Jude 13 ESV

Peter and Jude both believed that these false teachers were guilty of something far more egregious than sharing opinions that differed from their own. According to Jude, they were “ungodly people, who pervert the grace of our God into sensuality and deny our only Master and Lord, Jesus Christ” (Jude 4 ESV). Peter accused them of having “eyes full of adultery” and of being “insatiable for sin” (2 Peter 2:14 ESV). And he wasn’t done.

“They entice unsteady souls. They have hearts trained in greed. Accursed children!” – 2 Peter 2:14 ESV

Like the apostles, the false teachers’ tool of the trade was words. They propagated their opinions through the use of their powerful oratory skills. That’s why Peter opened his letter by stating, “we did not follow cleverly devised myths when we made known to you the power and coming of our Lord Jesus Christ…” (2 Peter 1:16 ESV).

In his first letter to the church in Corinth, Paul reminded his audience that he had not come to them with “lofty words and impressive wisdom” (1 Corinthians 2:1 NLT). He proudly confessed: “my message and my preaching were very plain. Rather than using clever and persuasive speeches, I relied only on the power of the Holy Spirit. I did this so you would trust not in human wisdom but in the power of God” (1 Corinthians 2:4-5 NLT).

When Paul had first arrived in Corinth, he had not tried to impress his audiences with his oratory skills or rhetorical acumen. In fact, he didn’t rely on human wisdom or his own personal speaking skills at all.

…we do not use words that come from human wisdom. Instead, we speak words given to us by the Spirit, using the Spirit’s words to explain spiritual truths. – 1 Corinthians 2:13 NLT

Peter accused the false teachers of doing just the opposite. Their words were “loud boasts of folly” with which “they entice by sensual passions of the flesh” (2 Peter 2:18 ESV). The Greek word that is translated as “loud boasts” is ὑπέρογκος (hyperogkos), and it literally means “over swollen” or “extravagant.” They used high-sounding language that was meant to impress and their listeners. And Jude used the very same word when describing the false teachers

These are grumblers, malcontents, following their own sinful desires; they are loud-mouthed boasters [hyperogkos], showing favoritism to gain advantage. – Jude 16 ESV

But Peter points out that their over-inflated words were nothing but meaningless vanity. The Greek word is ματαιότης (mataiotēs), which means “what is devoid of truth and appropriateness.” While their words may have been impressive to hear, they were empty of beneficial content. Like waterless springs, they contained no life. To borrow from Shakespeare, the words of these false teachers were nothing more than “a tale told by an idiot, full of sound and fury, signifying nothing.”

And Peter pointed out the folly of their self-proclaimed wisdom.

They promise them freedom, but they themselves are slaves of corruption. – 2 Peter 2:19 ESV

They were the enslaved promising freedom to their fellow captives. They were the blind leading the blind. And as Jesus so succinctly put it, “if one blind person guides another, they will both fall into a ditch” (Matthew 15:14 NLT).

What made these men so dangerous was their ability to coerce and convince others to walk away from the truth. Yet all the while, they were overcome by greed, lust, and the need for power and authority. And Peter knew that, if left unchecked, their powers of coercion would eventually drag others down with them.

…many will follow their sensuality, and because of them the way of truth will be blasphemed. – 2 Peter 2:2 ESV

This was Peter’s greatest concern. He feared that a steady diet of false promises and blasphemous teaching would eventually persuade weak-willed and spiritually immature believers to abandon the faith. Peter knew this was a very real possibility and he even described what it looks like when it happens.

…when people escape from the wickedness of the world by knowing our Lord and Savior Jesus Christ and then get tangled up and enslaved by sin again, they are worse off than before. – 2 Peter 2:20 NLT

It’s important to note that these false teachers were plying their wares within the local congregations. They were not disseminating their false doctrine among the lost, but among those who had placed their faith in Jesus Christ. They had targeted the body of Christ. Like the Serpent in Eden, these individuals had “crept in unnoticed” (Jude 4 ESV), and hidden within God’s garden – the church, where they were subtly and slyly asking, “Did God actually say…?” (Genesis 3:1 ESV). They were questioning the veracity of God’s word concerning Jesus, salvation, sin, and future judgment. They were encouraging infidelity and even immorality, and, ultimately, they were instigating open rebellion against God. And Peter warns his readers how devastating it would be if some of them bought into the lies and turned their backs on God.

It would be better if they had never known the way to righteousness than to know it and then reject the command they were given to live a holy life. – 2 Peter 2:21 NLT

There is a very real and serious question raised by Peter’s language. Is he promoting the idea that believers can somehow lose their salvation? What about once-saved, always-saved? Is Peter inferring that all those who buy into the lies of these false teachers will forfeit their citizenship as sons and daughters of God?

There are two possibilities here. First, Peter is suggesting that there are those within the local fellowship who have claimed to be Christ-followers, but whose faith was not genuine or sincere. Their willing association with the body of Christ had given them the false assurance of salvation, but they had never truly placed their faith in Christ. This made them highly susceptible to the lies of the false teachers.

But the second possibility is that there were within these local congregations, weak and immature believers whose faith was not yet strong enough to withstand the attacks of the enemy. They were those whom Paul referred to as “weaker brothers” (Romans 14; 1 Corinthians 8). Within every local congregation, there will be those who are strong in their faith and able to stand against the enemy’s relentless attacks. But there will also be those who are spiritually immature and prone to fall back into the old, ingrained habits they embraced before coming to faith in Christ.

Peter opened his letter by reminding his readers that God “has granted to us his precious and very great promises, so that through them you may become partakers of the divine nature, having escaped from the corruption that is in the world because of sinful desire” (2 Peter 1:4 ESV). Then he went on to encourage them to “make every effort to supplement your faith with virtue…knowledge…self-control…steadfastness…godliness…brotherly affection…and… love” (2 Peter 1:5-7 ESV).

In other words, Peter expected every believer to grow up in their salvation, continually adding to their character the attributes of Christ through the fruits of the Spirit. To not grow was unacceptable and, ultimately, dangerous.

For whoever lacks these qualities is so nearsighted that he is blind, having forgotten that he was cleansed from his former sins. – 2 Peter 1:9 ESV

Peter went on to remind them, “if you practice these qualities you will never fall” (2 Peter 1:11 ESV). This means that if they failed to practice these qualities, there was a very real possibility that failure was in their future. Falling away does not necessarily mean a loss of salvation. It can simply refer to a lack of fruitfulness in the life of a believer. It can and does happen all the time. When a believer fails to supplement their faith with the character of Christ made possible through the indwelling presence of the Spirit of God, they run the risk of remaining spiritual infants. The apostle Paul revealed that these weak and vulnerable believers were part of the local congregation in Corinth.

Dear brothers and sisters, when I was with you I couldn’t talk to you as I would to spiritual people. I had to talk as though you belonged to this world or as though you were infants in Christ. I had to feed you with milk, not with solid food, because you weren’t ready for anything stronger. And you still aren’t ready, for you are still controlled by your sinful nature. – 1 Corinthians 1:1-3 NLT

Peter was addressing local congregations that were having to deal with the influence of false teachers. His concern was that the weak and spiritually immature among them might fall prey to the predations of these men. He wasn’t worried about believers losing their salvation. But he was concerned that they could be easily persuaded to embrace their former pre-conversion lifestyles. Peter knew that the old sin nature remained actively alive within every believer. And his greatest concern was for those who lacked the spiritual strength to resist “the flaming darts of the evil one” (Ephesians 6:16 ESV).

Peter had a strong desire to warn the weak and vulnerable within the local congregations because they were the most susceptible to the relentless attacks of the enemy.

With an appeal to twisted sexual desires, they lure back into sin those who have barely escaped from a lifestyle of deception. – 2 Peter 2:18 NLT
