Peter opens his second epistle by addressing believers who have received faith through Christ’s righteousness, emphasizing God's power in granting them everything needed for a godly life. He encourages us to actively cultivate virtues such as goodness, knowledge, self-control, perseverance, godliness, mutual affection, and love. By diligently developing these qualities, we will be effective and fruitful, avoiding spiritual short-sightedness and confirming our calling, which ensures a rich welcome into God's eternal kingdom.
