Peter wrote 2 Peter to warn the church about false teachers spreading heresies from within. He encouraged Christians to grow in faith and knowledge of God. Peter outlined seven virtues believers should develop, with faith as the foundation. False teachers were prevalent and brought damaging teachings, immoral conduct, and sought personal gain. Their fate would be divine judgment, as seen in examples from the Bible. Scoffers would deny Christ's second coming, but Peter affirmed it based on Scripture and God's timing. He concluded by exhorting Christians to persevere through growing in grace and knowledge of Jesus.
