The sermon continues an ongoing expository series through 2 Peter, taking up chapter 2, verses 11 (from the latter half of verse 10) through 22. The preacher explains that chapter 1 encouraged believers to confirm their calling and election through obedience, faith in God's promises, godly living, and experiencing God's power. Chapter 2 pursues the very same goal — confirming the believers' calling and election — but by the opposite method: issuing a stark warning through a bleak portrait of false teachers who reject God's authority, ignore His commands, and indulge their own lusts under the banner of "freedom." The point is pastoral, not merely descriptive: whoever follows the path of these false teachers proves that they do not actually belong to Christ and have never truly received God's call.

The sermon works through four portraits of these false teachers. First, they are people who arrogantly blaspheme glory (likely the glory of Christ's second coming), and Peter contrasts them with angels who, though far more powerful, never use reviling language even when pronouncing judgment on such teachers before God. False teachers, by contrast, behave like unreasoning animals — creatures born to be caught and destroyed — because they slander what they do not understand.

Second, these teachers are brazen sinners who indulge in evil openly, even carousing during shared meals within the fellowship of the church, their eyes full of adultery and never satisfied with sin. The preacher illustrates their greed through the account of Balaam (Numbers 22), who, though warned by God, was lured by King Balak's money to curse Israel, until his own donkey miraculously rebuked him for his madness. Like Balaam, false teachers are driven by carnal, sexual, and material appetites, and they specifically prey on the spiritually weak and newly converted.

Third, in a brief but vivid image (v. 17), these teachers are compared to springs without water and mists driven by a storm — something that looks like it will refresh but, on approach, is nothing but a dried-up mirage, offering no life at all. This is set against Christ's teaching, which is a spring of living water welling up to eternal life; believers are called to discern which kind of teaching they are drinking from.

Fourth, and most severely, these teachers promise freedom to others while being themselves slaves of corruption — for a person is a slave to whatever has mastered him. The preacher connects this to the true doctrine of Christian freedom found in 1 Peter 2:16, Romans 6, and Galatians 5: believers are genuinely set free from the bondage of sin and from needing to keep the law to be justified, but this freedom is never a license for sin. False teachers twist this liberty, as they twist Paul's writings (2 Peter 3:16), into an excuse for sexual immorality and even into distorted promises of financial prosperity for "true believers." Those who once escaped the world's defilements through the knowledge of Christ but are again entangled and overcome are worse off than before — for it would have been better for them never to have known the way of righteousness than, having known it, to turn back from the holy commandment. The preacher likens this to a patient who stops taking antibiotics too early: the illness returns more resistant and severe than before. The chapter closes with two proverbs — "a dog returns to its own vomit" and "a sow, after washing, returns to wallow in the mire" — showing that such people's true nature was never changed, however clean they may have appeared outwardly.

From this passage the preacher draws two governing principles. First, quoting Christ's rebuke of Chorazin and Bethsaida in Matthew 11:21–22, much is required of those to whom much has been given; a congregation richly fed on expository preaching of the whole counsel of God must not grow complacent or take the Word for granted, but must continually hunger for and obey it. Second, Peter is not teaching that the salvation of the truly elect can be lost; rather, he is warning that outward, formal church membership — baptism, confirmation, attendance, even ministry involvement — does not by itself prove genuine regeneration. Those who fall away decisively reveal, as 1 John states, that "they were not of us." True children of God, having been made new creations, are instead preserved by God's power precisely as they are enabled to persevere — the doctrine of the perseverance of the saints understood not as passive security but as God actively sustaining believers in active obedience. The sermon closes with practical applications: churches must be rooted in expository preaching of the whole Bible, including its hard passages; parents and elders must themselves grow and model godliness so as not to be later rebuked by children they raised on the Word but failed to embody it before; and every believer, young or mature, must keep pressing forward in sanctification, since ceasing to grow is itself a danger.
