In his first epistle, Peter encouraged believers who were suffering persecution from a hostile culture. To stand firm, they would need to understand that their true security was in eternity, purchased for them by the blood of Christ. Christians are citizens of heaven, and they are aliens and strangers on the earth. When we learn to see things from this heavenly point of view, all that happens on earth takes on a different light.
In volume two of this series, Alistair Begg explains that although Christians live in the world, they do not fight with the weapons of the world. When faced with hostile authority, believers ought to follow the pattern of Christ and the apostles, who set an example of submission, obedience, and love. Whether in the household or the wider culture, following Christ means living by a standard the world does not recognize but that God honors.
