Chapter 21 brings John's Gospel to a close by showing that the risen Christ not only saves but continues to shepherd, restore, and send His people. Jesus reveals Himself as the living Lord who meets His people in ordinary life, provides for them, and commissions them for His purposes. Christ redeems Peter and charges him with shepherding His flock. The chapter emphasizes that discipleship is personal, calling each believer to follow Christ with obedience regardless of others’ paths or outcomes.
