Peter speaks of Christians as in exile in 1 Peter. What does life look like as an exile? Its primary feature is love for one another, for we are the ones who are there for each other and who will endure.
Seeing ye have purified your souls in your obedience to the truth unto unfeigned love of the brethren, love one another from the heart fervently (1 Peter 1:22).
Honor all men. Love the brotherhood. Fear God. Honor the king (1 Peter 2:17).
Above all things being fervent in your love among yourselves; for love covereth a multitude of sins (1 Peter 4:8).
