As mentioned in the introduction of this series on 1 Peter (read it here), Peter focuses much of his work on the conduct of his audience. They are facing trials. These trials have them doubting whether they are truly in “God’s grace.” Peter’s goal is to reassure them of their status (he has down that in the first 12 verses and will again throughout the book) and to make sure they “stand firm in God’s grace” (1 Peter 5:12). Standing firm in this grace means they need to maintain a certain type of conduct, even when facing trials. This comes to the forefront beginning in verse 13.
