John 21:21 (KJV)

What does John 21:21 mean?

John 21:21 shows Peter noticing another disciple and asking Jesus what will happen to that man’s future. Peter’s question, “Lord, and what shall this man do?” reveals his curiosity or concern about the other disciple’s path compared to his own.

In this scene, Peter is speaking to Jesus after Jesus has just spoken to him about his own future. The “him” Peter sees is widely understood to be the disciple John. Peter’s question comes right after Jesus has told Peter something significant about his own life and death, so Peter wants to know what will happen to his fellow disciple.

The Greek behind John 21:21

• The word “seeing” (εἶδεν, eiden, from G1492) means more than just noticing with the eyes; it often carries the sense of perceiving or paying attention to someone, which fits Peter’s careful observation of the other disciple.
• The word “what” (τί, ti, from G5101) is a direct and open-ended question, showing Peter’s genuine interest or perhaps concern about the other disciple’s future.
• The word “man” (οὗτος, houtos, from G3778) is a demonstrative pronoun, literally “this one,” emphasizing Peter’s focus on a specific individual, not just anyone in general.

Why John 21:21 matters

• This verse highlights Peter’s human tendency to compare his own journey with that of others, even after a personal conversation with Jesus.
• The question sets up Jesus’ response in the following verses, where Jesus gently redirects Peter to focus on his own calling rather than worrying about others.
• Understanding this exchange helps clarify the relationship between Peter, John, and Jesus, and shows how Jesus addresses individual paths among his followers.
