Fast forward a little bit in the story of Peter. After Jesus died and rose again, he spent a good 40 days on earth before he ascended back to heaven. One of those days included a personal moment with Peter where Jesus brought renewal to his life and calling. It's in John 21. Read all of chapter 21 (just 25 verses).
Give yourself a half hour to listen to it and take notes. It's well worth it.
