John 15:21 (KJV)

What does John 15:21 mean?

John 15:21 says that people will treat Jesus’s followers badly because of their connection to him, and the reason for this hostility is that those people do not truly know God, who sent Jesus. The verse points out that opposition to the disciples is rooted in a lack of understanding or relationship with God.

In this verse, Jesus is speaking to his disciples during his final teachings before his arrest. He is preparing them for the difficulties they will face because of their loyalty to him. Jesus explains that the rejection and mistreatment they will experience is not just personal, but is ultimately because the world does not recognize or accept the one who sent him—God the Father.

The Greek behind John 15:21

• The word "name" (ὄνομα, onoma) in Greek often refers not just to a label, but to a person’s character, authority, or reputation. Here, "for my name's sake" means the disciples will suffer because they are associated with everything Jesus stands for.
• The verb "sent" (πέμπω, pempō) is used for someone being sent with a purpose or mission. Jesus is emphasizing that he was sent by God, and rejection of him is also rejection of the one who sent him.
• The word "know" (οἶδα, oida) in Greek often means more than just factual knowledge—it can mean recognizing, understanding, or having a relationship with someone. The verse says those who oppose the disciples do so because they do not truly know God.

Why John 15:21 matters

• John 15:21 clarifies that hostility toward Jesus’s followers is not just about personal disagreements, but is deeply connected to people’s response to Jesus and to God himself.
• The verse highlights that being mistreated for following Jesus is not a sign of failure, but something Jesus anticipated and explained to his disciples.
• This verse ties into the larger section where Jesus prepares his followers for the world’s opposition, showing that their experiences are part of a bigger spiritual reality.
