Peter exhorts his fellow elders - he himself is a witness of the sufferings of Christ, and a partaker of the glory to be revealed. Shepherds (i.e., spiritual leaders) who serve eagerly and honestly, are examples to their flock.
1 Peter 5:2-4 Be shepherds of God’s flock that is under your care, watching over them - not because you must, but because you are willing, as God wants you to be; not pursuing dishonest gain, but eager to serve; not lording it over those entrusted to you, but being examples to the flock. And when the Chief Shepherd appears, you will receive the crown of glory that will never fade away.The youngsters must submit to their elders. God opposes the proud, but gives grace to the humble.
Peter then warns us about the devil, who is looking for an opportunity to devour us.
1 Peter 5:8-9 Be alert and of sober mind. Your enemy the devil prowls around like a roaring lion looking for someone to devour. Resist him, standing firm in the faith, because you know that the family of believers throughout the world is undergoing the same kind of sufferings.May you be perfected, established and strengthened after having suffered for a while.
Peter signs off his first letter by greeting one another with a kiss of love and proclaiming peace to all who are in Christ.
