Jim Osman examines false teachers through an exposition of 2 Peter 2:1-3, warning believers against three critical dangers. False teachers secretly introduce destructive heresies into the church, not announcing their deception but creeping in quietly while using Christian language and claiming orthodox beliefs. These false teachers promote destructive doctrines that damn unbelievers and render Christians useless and unfruitful. Their depraved desires are marked by sensuality, and their deserved doom brings swift destruction upon them.

Believers must beware lest they be deceived by their teachings, seduced by their lusts, or exploited by their greed. The sermon emphasizes that sound doctrine and godly character must go together, as false teachers lack both biblical authority and moral integrity, thereby exerting a destructive influence.
