Peter expressed a concern about the conflict in a church, in between the elders and the young members. He encouraged the elders 'Be shepherds of God’s flock (the young members) 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; (1 Peter 5:2 NIV), and on the other way round, he encouraged the young members (the flock) 'In the same way, you who are younger, submit yourselves to your elders. All of you, clothe yourselves with humility toward one another' (1 Peter 5:5 NIV)
Conflict is a consequence of insufficient trust and respect of each other, and conflict creates anxiety to both parties. When the conflict cannot be resolved, it will form a downward spiral curve that eventually dissect the coalition of the church.
Peter reminded both of them that 'Your enemy the devil prowls around like a roaring lion looking for someone to devour.' (vv5:8) So do not act on their flesh but submitted to 'God mighty hand' (vv5:6), for God 'opposes the proud but shows favor to the humble.' (vv5:5) In this way, their anxiety due to the conflict would be released.
