The First Epistle of Peter, written by the apostle Peter, offers encouragement and instruction to believers facing persecution and hardships. Peter reminds them of their identity as a chosen people, a royal priesthood, and a holy nation. He encourages them to stand firm in their faith, to respond to persecution with grace and love, and to live in obedience to God's Word. 1 Peter highlights the hope of the believer's inheritance, the importance of holy living, and the call to follow Christ's example of suffering and redemption.
