Peter spares no words in describing the ruin of false teachers. He likens them to Balaam, who was so blinded by greed and pride that he could not see the angel of the Lord standing before him (Numbers 22:22–35). In a moment meant to shame the proud, God opened the mouth of a donkey to rebuke the prophet, showing that even animals could discern what Balaam could not. Likewise, these false teachers exalt themselves as spiritual guides, yet are less discerning than beasts.
Peter calls them “waterless springs” (v. 17), promising refreshment but leaving souls thirsty and dry. Their promises of freedom only bind others deeper into corruption (vv. 18–19). In truth, freedom is not found in casting off restraint but in Christ alone: “For freedom Christ has set us free; stand firm therefore, and do not submit again to a yoke of slavery” (Galatians 5:1).
The most sobering warning comes at the end: having tasted the knowledge of Christ, they return to the filth of the world. Like a dog returning to its vomit (Proverbs 26:11) or a pig returning to the mire, they prove that knowledge without transformation only multiplies guilt. Jesus gave the same warning: “The last state of that person is worse than the first” (Matthew 12:45).
We are called, then, to humility. Pride blinds, but the meek see clearly. The example of Balaam and these false teachers reminds us to cling to Christ, not merely in name, but in the transforming freedom He alone provides.
