John 21:17 He said to him the third time, “Simon, son of Jonah, do you love Me?” Peter was grieved because He said to him the third time, “Do you love Me?” And he said to Him, “Lord, You know all things; You know that I love You.” Jesus said to him, “Feed My sheep.”
Jesus asked the question “Do you love me?” three times to Peter. He restored Peter through the three denials that Peter had stated before, and He also wanted to show how the church should be lead. The first two times talked about unconditional, godly love. The third time talked about family/brotherly love. Spiritual leaders should be a “Father” and a “Brother” in a sense!
