In the Gospel reading for today (John 21:1-19) Jesus restores Peter to ministry. He does so by asking Peter three times: “Do you love Me?” Each response by Peter “Yes, Lord. You know that I love you,” is met with Jesus saying, “feed My lambs”; “Shepherd My sheep”; “Feed My sheep.” This parallels Peter’s three-fold denials when asked if He was one who followed Jesus. Peter was forgiven, restored, and called to care for people.
Note how Peter writes about this change in 1 Peter 5:1-4:
1 I exhort the elders who are among you, as one who is also an elder and a witness of the sufferings of Christ as well as a partaker of the glory that shall be revealed: 2 Shepherd the flock of God that is among you, take care of them, not by constraint, but willingly, not for dishonest gain, but eagerly. 3 Do not lord over those in your charge, but be examples to the flock. 4 And when the chief Shepherd appears, you will receive a crown of glory that will not fade away.
(1 Peter 5:1–4 MEV)
