Believed to be written by the apostle Peter to scattered and persecuted Christians, 1 Peter offers encouragement and guidance. He reminds them of their new identity as God's chosen people and the hope they have in Jesus' return. Even though they face suffering, Peter reframes it as a chance to reflect Christ's character and a test of their faith. The book emphasizes living a holy life and enduring hardship while offering practical instructions for Christian conduct within families and society.
