They are committed to working together. Peter stresses the power of submission throughout his book. Mutual submission is the key to the pattern Christ left for the church. Christians find freedom in their submission to God. They honor all people and submit to lawful civil authority.
Christian slaves are free to submit to their masters.
Wives are taught to submit to their husbands. Now Peter is admonishing all believers to submit to God and to one another. They keep watch over you as men who must give an account. Obey them so that their work will be a joy, not a burden, for that would be of no advantage to you. Love the brotherhood of believers, fear God, honor the king.
