2 Peter.

2 Peter is a short general epistle written with the urgency of a final pastoral charge. The writer presents himself as Peter nearing the end of his life, and he addresses believers who share the same precious faith. The letter's central concern is how Christians remain faithful when false teachers distort grace, encourage corruption, and question the Lord's promised coming.

Chapter 1 establishes the positive foundation. God has already granted everything needed for life and godliness, so believers are called to supply their faith with virtue, knowledge, self-control, endurance, godliness, brotherly affection, and love. Peter joins visible growth with lasting assurance, then grounds the church's confidence in eyewitness testimony and the prophetic word carried by the Holy Spirit.

Chapter 2 exposes the false teachers who deny the Master while using greed, sensuality, and fabricated words to exploit others. Peter places their apparent success inside God’s established pattern of judgment and rescue: God judged rebellious angels, the ancient world, and Sodom, while preserving Noah and rescuing Lot. The chapter’s sharpest irony is its promise of freedom. People who are themselves mastered by corruption cannot lead others into freedom.

Chapter 3 answers scoffers who treat the continuing course of the world as proof that Christ will not return. Peter calls the church to remember creation, flood, prophets, apostles, and the Lord's patience, which is salvation. The promised day of the Lord brings both judgment and new creation, so waiting becomes holy conduct, peace, vigilance, and continuing growth in grace and knowledge.
