Thus far, Peter has affirmed that Christians have been chosen by God and set aside for His purposes. We should not be surprised by suffering, and we should not respond to persecution by rebelling against our human authorities. Our suffering in both cases points the world to our hope in Christ and allows us to follow in Jesus’ steps. Peter here concludes his letter with instructions to the elders, teaching on humility, and a final warning to be sober-minded and alert.
