The apostle Peter wrote his first letter to various churches in Asia Minor, probably while already in the city of Rome. In this letter, he emphasized the importance of the rebirth that baptism brings to believers, and how those who have received this very special sacrament should conduct themselves in a world dominated by sin and error.
In several passages, the apostle refers to the early Christians in Asia Minor as foreigners and people passing through. And this bears a great resemblance to some of Paul's expressions, such as when the apostle of the Gentiles refers to the citizens of heaven in his Epistle to the Philippians (Philippians 3:20). And this makes sense because in the doctrine of the Kingdom of God every person must choose between living according to the flesh and living according to the spirit, each person must choose between making error a habit, a custom, or making error an exception, the worldly and the heavenly are before the eyes of men. And in this election, there are no gray areas, no middle ground. This is why the apostle Peter wrote with wisdom: "I urge you, as foreigners and exiles, to abstain from sinful desires, which wage war against your soul" 1 Peter 2:11.
In the letter written by Peter, and this is consistent with the writings of Paul, righteousness, mercy (compassion, gentleness, kindness), and the fear of God (constancy, firmness, devotion) are gifts that must necessarily be lived for faith and hope to bear fruit.
This is why the apostle Peter, after alluding to baptism, gave a series of practical recommendations on how a Christian should behave in the world: "Show proper respect to everyone, love the family of believers, fear God, honor the emperor" 1 Peter 2:17. And Peter summarized this spiritual truth in other words: "By doing good you should put to silence the ignorance of foolish people" 1 Peter 2:15.
Christian behavior, then, should be an example for those who live subjected to passions, fleeting desires, and ignorance, and this is because the Kingdom of God taught by Jesus opposes human destructiveness. And so Peter concluded in his epistle that it is in this way that Christians must lead a blessed life in imitation of God.
