The Book of 2nd Peter is a letter from the Apostle Peter, written to strengthen believers in their faith and warn them against false teachers. Peter emphasizes the need for spiritual growth, urging Christians to pursue virtue, knowledge, self-control, and godliness. He reminds them of the certainty of Christ's return, encouraging vigilance and holiness in light of that future day. A central theme is the reliability of God's Word and the danger of heresies that seek to distort it. 2nd Peter calls believers to stand firm in truth, live godly lives, and eagerly await the fulfillment of God's promises.
