“But there were also false prophets among the people, even as there will be false teachers among you, who will secretly bring in destructive heresies… and many will follow their destructive ways… by covetousness they will exploit you with deceptive words.”
Were and Will — Then and Now
Peter dedicates this entire chapter to the danger of false teachers, and it is the longest sustained warning about them in the New Testament. Two words in verse 1 frame the entire discussion: were and will. There were false prophets in Israel’s past — all the way back to Deuteronomy 13:1, God warned His people that even a prophet who performed signs and wonders must be rejected if he leads people after other gods. And there will be false teachers in the church. The danger from within is often more devastating than opposition from without. An apple can look perfect on the outside while larvae planted before the fruit even formed eat it hollow from within. This is how false teachers operate: they embed themselves in the community before anyone recognizes the rot.
Vance Havner put it memorably: “Satan is not fighting churches. He’s joining them. He does more harm by sowing tares than by pulling up wheat. He accomplishes more by imitation than by outright lies.” The word false in Greek is pseudo — to pretend, to impersonate. These people come in sheep’s clothing (Matt. 7:15) — appearing to be shepherds, using Christian vocabulary — but they are using a different dictionary. Jeremiah 6:14 captured their message: “Peace, peace, when there is no peace.” A false sense of security, a smooth road that leads to destruction (Matt. 7:13–14).
Destructive Heresies — Plastic Words
The word heresy literally means to make a choice — false teachers feed people lies and cause them to make the wrong choice. At the center of every cult is a distortion of the person and work of Jesus Christ. Some deny the inspiration of Scripture; others deny man’s sinfulness; others deny eternal judgment. All of them ultimately deny the Lord who bought them (v. 1) — not that they were saved, but that Christ’s death was sufficient for all (1 John 2:2) and they are rejecting that provision for themselves and others. The word Peter uses for “exploit” in verse 3 is plastos — from which we get our English word plastic. Bendable. Twistable. These teachers come into a Christian environment, use Christian words, but the words mean something different. They use our vocabulary but not our dictionary. Their motivation is covetousness: “by covetousness they will exploit you” (v. 3). As 1 Timothy 6:5 says, they see ministry as a means of gain — coming to fleece the flock, not feed it.

Verses 4–6: The Doom — Three Examples of Judgment
2 Peter 2:4–6
“For if God did not spare the angels who sinned, but cast them down to hell and delivered them into chains of darkness, to be reserved for judgment; and did not spare the ancient world, but saved Noah… and turning the cities of Sodom and Gomorrah into ashes, condemned them to destruction, making them an example to those who afterward would live ungodly…”
Heavenly Judgment — The Fallen Angels
Peter gives three examples from history to prove that God’s judgment on false teachers is certain, even if delayed. The first is heavenly judgment: God did not spare even angels who sinned. Isaiah 14 records Satan’s five “I will” declarations — he would ascend to heaven, exalt his throne, sit on the mount of the congregation, ascend above the clouds, and be like the Most High. Five expressions of pride that brought him from the position of heaven’s anointed worship leader to the abyss. Revelation 12:4 tells us he took a third of the holy angels with him. Genesis 6:4 and Jude 6 describe a further specific sin in the days of Noah, when certain fallen angels “did not keep their proper domain” and were confined in chains of darkness to await final judgment. Peter’s point: if God did not spare angels He had created and placed in His own presence, He will certainly not spare false teachers.
Worldwide Judgment — The Flood
The second example is global: the ancient world perished in the flood, yet God saved Noah and seven family members. Genesis 6:3 tells us God gave mankind 120 years to repent — 120 years during which Noah built the ark in the middle of a desert, a massive object lesson preaching judgment. Not one person heeded the message except Noah’s own family. They just kept eating, drinking, marrying, and giving in marriage until the flood came (Luke 17:26–27). This illustrates God’s patience: He is not eager to judge, He gives time. Genesis 6:3 says His Spirit will not always strive with man — but when He has given every opportunity and nothing changes, judgment comes. Jesus said the days of the Son of Man will be just like the days of Noah (Luke 21:28) — and when we look at the wickedness escalating around us, the comparison becomes more vivid every year.
Localized Judgment — Sodom and Gomorrah
The third example is localized judgment: God turned Sodom and Gomorrah into ashes and made them “an example to those who afterward would live ungodly.” Jude 7 explains the sin that characterized these cities: they gave themselves over to sexual immorality and went after “strange flesh” — the specific sin of homosexuality, from which we derive the term sodomy. Leviticus 18:22 is unambiguous: “You shall not lie with a male as with a woman; it is an abomination.” But the broader principle is equally important: God does not grade on a curve. He does not give passing marks to those who are mostly good, or excuse sin because it is now culturally normalized or protected by law. 1 Corinthians 6:9–11 lists a broad catalog of sins — fornication, idolatry, adultery, homosexuality, theft, covetousness, drunkenness — and states that those who habitually practice such things will not inherit the kingdom of God. But then come the most encouraging words: “And such were some of you. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ.” The door of salvation remains open. What God judges is the refusal to change, the insistence on remaining in what He has named sin.

Verses 7–9: The Deliverance of True Believers
2 Peter 2:7–9
“…and delivered righteous Lot, who was oppressed by the filthy conduct of the wicked… the Lord knows how to deliver the godly out of temptations and to reserve the unjust under punishment for the day of judgment.”
Noah — Our Ark Is Christ
Nestled inside the doom of false teachers are two examples of God’s deliverance of true believers. Noah floated above the judgment on the wood of the ark; our judgment took place on the wood of the cross. The waters of the flood pounded the ark but did not destroy those inside; our sin was borne by Christ on Calvary and will never touch us again. Christ is our Ark. First Thessalonians 5:9 promises that “God did not appoint us to wrath, but to obtain salvation through our Lord Jesus Christ.” Warren Wiersbe wrote: “The world was buried in the baptism of the flood, but Noah was lifted up above it — a picture of resurrection and salvation.”
Lot — How Far God’s Grace Reaches
The example of Lot is one of the most astonishing portraits of grace in all of Scripture. When Peter calls him “righteous Lot,” most readers are shocked — and that is exactly the point. Lot’s progression through Genesis is a study in spiritual compromise. In Genesis 13 he chose the well-watered plain near Sodom, driven by what he saw, not by faith. By Genesis 14 he was dwelling in Sodom. By Genesis 19 he was sitting in the city gate — the seat of city elders, civic leadership. First he pitched his tent near Sodom; then he moved inside Sodom; then Sodom moved inside him. When the angels arrived to rescue him, Lot lingered (v. 16) — he could not decide whether he even wanted to leave. He offered his daughters to the mob. He was so carnal that God had to literally take him by the hand and drag him out of the city. And yet — God saved him. Why? Because he was a believer, however far he had drifted. God’s grace reaches further than our worst season of carnality.
Isaiah 43:1–3 captures the promise: “Fear not, for I have redeemed you; I have called you by name; you are Mine. When you pass through the waters, I will be with you… when you walk through the fire, you shall not be burned.” God saved through water (Noah); God saved through fire (Lot). He delivers both ways. Peter’s closing statement in verse 9 holds both truths simultaneously: “the Lord knows how to deliver the godly out of temptations and to reserve the unjust under punishment for the day of judgment.” Every true believer can rest in the first half of that sentence. But it is not a license for carnality — Lot’s story is a warning as much as it is an encouragement. Living near Sodom leads to living in Sodom, which leads to Sodom living in you.

Verses 10–17: The Depravity of False Teachers
2 Peter 2:10–17
“And especially those who walk according to the flesh in the lust of uncleanness and despise authority… presumptuous, self-willed… they have forsaken the right way and gone astray, following the way of Balaam the son of Beor… These are wells without water, clouds carried by a tempest.”
Walk in the Flesh — Despise Authority
Peter now describes what false teachers look like from the inside out. They walk according to the flesh — their fallen nature governs everything. In stark contrast to Christ, who “made Himself of no reputation” (Phil. 2:6–7) and took on the form of a bondservant, false teachers are “presumptuous and self-willed” (v. 10) — arrogant, driven by pride, unwilling to be corrected or held accountable. They despise all authority: children are to submit to parents (Eph. 6:1), employees to employers (Eph. 6:5), citizens to government (Rom. 13:1), church members to church leadership (Heb. 13:17). False teachers acknowledge none of it. They also “speak evil of dignitaries” (v. 10) — the Greek word is doxa, meaning glory. Peter is referring to angels, the glorious ones who dwell in God’s presence. These teachers flippantly speak against heavenly realities, while even the mighty archangels do not bring reviling accusations but entrust themselves to God. The contrast between arrogant teachers and humble angels is striking.
Brute Beasts — Unreasoning Animals
Peter calls them “natural brute beasts made to be caught and destroyed” (v. 12) — unreasoning animals, driven by instinct. The distinction is significant: God breathed into man the breath of life and man became a living soul (Gen. 2:7). Every person has a soul that is eternal. Animals operate on instinct; humans have the capacity to reason, to make choices, to seek God. False teachers abandon that higher capacity entirely and operate purely on fleshly instinct — driven by desire, not truth. Galatians 6:7–8 speaks to all of us: “Whatever a man sows, that he will also reap. He who sows to his flesh will of the flesh reap corruption.” These men are sowing false teaching, and they will reap accordingly.
Carousing in Daytime — Experts in Greed
They “carouse in the daytime” (v. 13) — doing openly what most do under cover of darkness. They are “spots and blemishes” — Old Covenant language for defective sacrifices. God demanded the best of the flock; these men are the worst. They have infiltrated the agape feasts, the home fellowship gatherings of the early church, something like today’s covered-dish life groups — creeping in to mislead those who are most vulnerable. Their hearts are trained in “covetous practices” (v. 14) — the Greek is gymnasio, from which we get gymnasium. Like well-trained athletes, they have mastered the craft of spiritual manipulation for financial gain. The NIV translates this simply: “experts in greed.”
Balaam — The Prophet for Hire
Peter’s example from Numbers 22–25 is vivid. The king of Moab hired Balaam the prophet to curse Israel. God said no. Balaam kept pushing — “let me inquire again” — until God permitted, then took him on the journey anyway. God opened the mouth of Balaam’s donkey to rebuke him. Every time Balaam tried to curse Israel, God put a blessing in his mouth. But unwilling to lose the money, Balaam counseled the king: send your women to entice the men of Israel into idolatry and immorality, and God will judge them Himself. That’s exactly what happened. Balaam is the prototype of the prophet for hire: a person with genuine prophetic gifts who uses them for personal profit, leading people into spiritual compromise. Peter says these false teachers have “forsaken the right way” and followed his path.
Wells Without Water — Clouds Without Rain
The final image in this section is devastating: “wells without water, clouds carried by a tempest” (v. 17). In the arid Middle East, a traveler discovering a dry well would be crushed — they had come expecting life-giving water and found nothing. A farmer who sees clouds forming hopes for rain on his crops; empty clouds bring only disappointment. False teachers promise so much and deliver nothing. In contrast, Jesus said to the woman at the well in John 4:14: “Whoever drinks of the water that I shall give him will never thirst. But the water that I shall give him will become in him a fountain of water springing up into everlasting life.” The world looks for fulfillment in relationships, fame, possessions, and power — and keeps coming up empty. Only Jesus truly satisfies. False teachers exploit that longing and leave people emptier than before.

Verses 18–22: The Deception of False Teachers
2 Peter 2:18–22
“For when they speak great swelling words of emptiness, they allure through the lusts of the flesh… while they promise them liberty, they themselves are slaves of corruption… A dog returns to his own vomit, and a sow, having washed, to her wallowing in the mire.”
Great Swelling Words — Paul vs. False Teachers
Despite having nothing real to offer, false teachers are often gifted communicators — sometimes among the most compelling speakers in their field, backed by spiritual forces that make them compelling. But eloquence is not truth. When Apollos came to Ephesus (Acts 18), he was described as an eloquent speaker — yet had to be taken aside and corrected in the ways of the Lord. The Apostle Paul, who wrote half the New Testament, deliberately avoided relying on oratorical skill. In 1 Corinthians 2:4 he wrote: “My speech and my preaching were not with persuasive words of human wisdom, but in demonstration of the Spirit and of power.” Warren Wiersbe commented: “Paul preached to express, not impress. He knew the difference between communication and manipulation.” False teachers use great swelling words of emptiness — the vocabulary of faith without the reality of it.
Who Do They Deceive?
Peter identifies the primary targets of false teachers as “the ones who have actually escaped from those who live in error” (v. 18) — that is, they primarily deceive people who have had some connection to the church. A television documentary on cults found that over 90% of those deceived by cults had been raised in a church or involved in church at some point. The solution is not fear but depth — those who are thoroughly grounded in God’s Word are far harder to pull away. This is why Peter’s whole letter calls us to keep growing: not intellectual accumulation but deep, personal, experiential knowledge of Jesus Christ.
Promising Liberty, Enslaved to Corruption
The supreme irony of verse 19: “while they promise them liberty, they themselves are slaves of corruption.” False teachers advertise freedom — from rules, from repentance, from accountability. But true freedom is only found in Christ. Jesus said, “If the Son makes you free, you shall be free indeed” (John 8:36). The world’s version of freedom is slavery to the flesh; Christ’s version of freedom is genuine liberty from the bondage of sin.
Peter closes with two proverbial images (quoting Proverbs 26:11): a dog returning to its vomit, and a pig in a tuxedo that goes straight back to the mud when released. These images describe false teachers who have not been genuinely converted. They may have absorbed Christian environment and vocabulary, appeared outwardly religious, but their nature has never been changed. When freed from external constraints, they return to what they truly are. This also explains the sobering statement of verse 21: “it would have been better for them not to have known the way of righteousness, than having known it, to turn from the holy commandment.” Greater light brings greater accountability. Louis Grizzard, writing about a chain restaurant that served powdered mashed potatoes instead of the real thing, asked at the end of his column: “What’s real anymore?” That is exactly the question Peter leaves us with as we close chapter 2. The answer: God’s Word. Compare everything to it. Test every teacher by it. Grow in it. That is the only way to keep growing.
