John 21 is the epilogue to The Book of John, sort of a post-credits scene that gives the viewer insight into what's next for Christ's followers both corporately, and as individuals. The text gives us a portrait of what the church will look like, and what disciples are called to do - "Feed Jesus' sheep." Frederick Bruner wrote , “Jesus entrusts very human people with his mission, people just like Peter; namely, problematic human beings: errant, sin-marred, but sincerely repentant human beings who confess their sins and want to be real Christians. Our Gospel is teaching us on its final page that Jesus takes people who qualify exactly as much as Peter does; people who have failed; sometimes, quite awfully.” The thing that qualifies Peter and people like us to feed Jesus’ lambs, to be a part of Jesus’ mission to the world to transform the lives of other problematic, errant, sin-marred human beings is looking inside yourself and understanding you have nothing to offer – but what you have, you’ll give.
