Peter turned and saw that the disciple whom Jesus loved was following them. (This was the one who had leaned back against Jesus at the supper and had said, “Lord, who is going to betray you?”) When Peter saw him, he asked, “Lord, what about him?” Jesus answered, “…what is that to you? You must follow me.” (John 21:20–22, NIV).
My Musings – We can spend way too much time looking back to find out what the other guy is doing. God has called each of us to do our part. Not their part.
My Advice – Be faithful to what you are called to.
