A couple weeks ago I had the opportunity to preach on 1 Peter 3:8-12. Though I didn’t use this quote in my message, I found it to be a helpful in understanding the message of this text, especially given that these verses are a summary the previous chapter or so.
“[Believers] are encouraged to persevere, knowing that a great reward will be theirs on the day of salvation. Such perseverance is exhibited by living a godly life, living as good citizens, model slaves, gentle wives, and understanding husbands. When believers live in such a way, they indicate that they are placing their hope in God rather than in the joys and comforts of this world… those who hope and trust in God and in his future reward will have the strength to endure whatever comes their way in the present. When believers set their hope on the future, they reveal that their salvation comes from the cross of Christ.”
— Thomas Schreiner’s commentary on 1 Peter, p 45
