John 15:21

But all these things will they do unto you for my name’s sake, because they know not him that sent me.

John 15:21 (KJV)

Context

In John 15, Jesus speaks to His disciples on the night before His crucifixion, using the metaphor of the vine and branches to teach them about abiding in Him. He has just told them that a servant is not greater than his master (John 15:20), so if the world persecuted Him, it will also persecute those who follow Him. Verse 21 flows directly from that warning, explaining both the cause and the purpose of the hostility His disciples will face.

Meaning

The phrase “all these things” refers to the various forms of opposition, hatred, and mistreatment believers will encounter as they spread the Gospel. Jesus makes clear that this persecution is not because of any wrongdoing on the disciples’ part, but “for my name’s sake“—because they are called by His name, profess His name, and confess Him to be the Messiah and Redeemer. The world’s hostility is ultimately rooted in ignorance: “because they know not him that sent me.” This is not a mere lack of information, but a failure to acknowledge the Father as the One who sent Jesus. The world does not know the Father, and because Christ and His disciples assert this truth, they become objects of hatred.

Biblical connections

This verse connects to the following context, where Jesus states that whoever hates Him hates the Father as well (John 15:23), and that this fulfills what is written in their Law: “They hated me without reason” (John 15:25). The rejection of the disciples is therefore part of the larger rejection of Christ and the Father.

Application

As followers of Christ, we should not be surprised if we encounter opposition, criticism, or even persecution because of our identification with Jesus. Our commitment to Him and our proclamation of His name may be met with hostility from those who do not understand or accept God’s truth. Yet this passage provides assurance that suffering for Christ’s name is a mark of belonging to Him, not a sign of failure. We are called to respond to persecution with love and grace, just as Jesus did, and to deepen our knowledge of God and His Word so that we can share the message of salvation and respond to opposition with wisdom and love.

Reflection

When we face rejection for our faith, we can find comfort in knowing that our suffering is on account of His name and that the world’s rejection stems from its ignorance of God. Our response should reflect the character of Christ, who prayed for His persecutors and entrusted Himself to the Father.
