2 Peter 2:17-22
Through these false teachers, Satan is preparing the web of lies and deceit that he will use to deceive the world. Despite their bravado, the boasts of the false teachers are nothing but “folly” (mataiotēs), a word highlighting the emptiness of life apart from God (Eccles. 1:2).
Sinful passion is personified as working in the world to produce corruption (2 Pet. 1:4) and is a defining characteristic of the false teachers (2:10). Peter appears to have sexual passions in view here, evidenced by the use of the word “sensual” (aselgeia). The very sensuality that ensnared the false teachers (2:2) and Lot’s neighbors (2:7) has become the bait by which the false teachers lure the vulnerable into their web of deceit.
Sin and corruption are pictured as powers that conquer a person. Such a person is “enslaved” (douloō); corruption has gained complete mastery over him. These verbs are both in the perfect tense, stressing that this is the state/condition of the person described. Slavery to sin takes many forms, but in the end the result is the same: death (Rom. 6:20–23). Only the gospel can deliver from its grip (Rom. 6:17–18).
This escape came “through the knowledge of our Lord and Savior Jesus Christ.” By using language similar to 1:2–11, Peter indicates these people have professed faith in Christ at some point but have since proved their profession to be false.
they are again entangled in” the defilements of the world. Unlike the good soldier who avoids entanglement with worldly affairs (2 Tim. 2:4), the false teachers are “entangled” (emplekō) in the same kind of sin that characterized their life before professing Christ.
Those who have professed faith in Christ but then returned unrepentantly to their sinful ways are in a worse state than before their profession (Heb. 6:4–8). Peter likely echoes Jesus’ own teaching in Matthew 12:43–45, where he describes a man who, after having a demon cast out of him, ends up with seven evil spirits worse than the first; as a result, “The last state of that person is worse than the first” (Matt. 12:45).
Peter’s larger theological point is that God’s judgment on people such as these will be more severe than the judgment on those who never made any profession of faith in Christ. That does not mean that ignorance will excuse anyone’s sin. But those who claim to believe the gospel but then return to a habitual pattern of unrepentant sin in their rejection of Jesus will be far worse off on judgment day.
Peter may also be echoing the teaching of Jesus, who said, “Do not give dogs what is holy, and do not throw your pearls before pigs, lest they trample them underfoot and turn to attack you” (Matt. 7:6). It was common for Jews to regard Gentiles as dogs and pigs; Peter takes these terms and applies them to the false teachers, on the basis not of ethnicity but of how they live.
