"His divine power has given us everything we need for a godly life through our knowledge of him who called us by his own glory and goodness." (2 Peter 1:3)
Second Peter opens with one of the most extraordinary statements in the New Testament: God's divine power has given us everything we need for a godly life, and through his great and precious promises we may participate in the divine nature, having escaped the corruption in the world caused by evil desires. The phrase partakers of the divine nature is the scriptural foundation of the Eastern tradition's theology of theosis, deification: the goal of the Christian life is not merely moral improvement or even the forgiveness of sins but genuine participation in the life of God. The Catechism calls this the ultimate purpose of the Incarnation: the Word became man so that man might become divine, sharing in the life of the Trinity through grace (CCC 460).
For this very reason, believers are to add to their faith goodness, and to goodness knowledge, and to knowledge self-control, and to self-control perseverance, and to perseverance godliness, and to godliness mutual affection, and to mutual affection love. For if they possess these qualities in increasing measure, they will be neither ineffective nor unproductive in their knowledge of Christ. The author urges them to confirm their calling and election, for if they do these things they will never stumble and will receive a rich welcome into the eternal Kingdom.
The author recalls the Transfiguration: we were eyewitnesses of his majesty; we heard the voice from heaven saying this is my Son. And we have the prophetic word made more certain, a light shining in a dark place, until the day dawns and the morning star rises in our hearts. No prophecy of Scripture came about by the prophet's own interpretation, for prophecy never had its origin in the human will, but prophets, though human, spoke from God as they were carried along by the Holy Spirit.
Brothers and sisters, his divine power has given us everything we need for a godly life. Everything. Not most things. Not almost everything. Everything, through the knowledge of him who called us. Whatever you are facing today that seems impossible, the divine power that has already given everything needed for a godly life is available to you. You are not lacking. You have been given everything. Draw on it.
Lord God, your divine power has given us everything we need for godly life. Let us participate in the divine nature, escaping the corruption of the world and growing in the chain of virtues that leads from faith to love. Confirm our calling and election. Through Christ our Lord. Amen.
