Peter ends his letter to believers facing increased exposure to false teachers, with warnings of the great judgments of God to come upon the wicked of the earth. He urges them to grow in grace and knowledge.
Peter tells believers to stick to Scripture; penned and preached by prophets and apostles. Many are wicked but God waits, giving them space to repent. God is not impressed by scoffers, He is patient with them.
Peter lays out the methods of false teachers, making it clear that they target believers, they promise the very thing that they steal: freedom! He warns that their victims suffer a worst fate than those who never believed.
Peter, sketching the ways and destiny of false teachers, likens them to brute beasts who speak evil; he warns us that they will deceive and entice the unstable, but also that they will perish for hell awaits them.
