The First Letter of Peter is a message of hope and encouragement written to Christians scattered across Asia Minor who were facing suffering and social rejection because of their faith. Traditionally attributed to the apostle Peter, the letter reminds believers of their identity in Christ and calls them to live holy and honorable lives in the midst of a hostile world. It blends rich theology with practical exhortation.

Peter begins by praising God for the new birth and living hope believers have through the resurrection of Jesus Christ. He reminds them that their inheritance is secure, even though they are grieved by various trials. Their faith, though tested, will result in praise and glory when Jesus is revealed. Peter calls them to be holy, as God is holy, and to live as strangers and exiles in this world.

A major theme is Christian identity. Believers are described as a chosen people, a royal priesthood, and living stones being built into a spiritual house. Even though they are rejected by the world, they are honored by God. Peter exhorts them to live such good lives among unbelievers that even those who oppose them may see their good deeds and glorify God.

Peter gives specific instructions for honorable conduct in society—toward governing authorities, masters, spouses, and the church community. He encourages humility, submission, and gentleness, especially in suffering. Jesus is presented as the model for enduring unjust treatment, having suffered for righteousness' sake without retaliation.

The letter ends with encouragement to remain steadfast in suffering, casting all anxieties on God and standing firm against the devil. Peter reminds believers that after a little while of suffering, the God of all grace will restore, confirm, strengthen, and establish them. 1 Peter offers comfort and clarity to Christians living in difficult times, urging them to remain faithful, do good, and set their hope fully on the grace to be revealed in Christ.
