1 John 3:5 says that Jesus appeared in the world for a specific purpose: to take away sins, and that there is no sin in him. The verse answers a question every believer eventually asks, namely why Christ came and what kind of person he is. John wrote it to the members of the churches he cared for, Christians who needed to be reminded who Jesus is and what his coming accomplished.
You know that he was revealed to take away our sins, and in him is no sin.

What 1 John 3:5 Means
The phrase “he was revealed” points to the appearing of Jesus in human history. John often uses the language of revelation to describe the incarnation, the moment when the eternal Son became visible in a body and walked among people. The reason for that appearing is stated plainly: “to take away our sins.” The Greek idea behind “take away” carries the sense of lifting a burden off someone and carrying it away, which is why the image fits so well with the Lamb of God imagery elsewhere in the New Testament.
The second clause makes a striking claim: “in him is no sin.” This is a statement about the character of Jesus. Sin is not a part of who he is, and he is the one fully righteous person who can deal with sin without being compromised by it. The verse does not promise that believers will stop sinning in this life, and it does not say that Christians have already reached sinlessness. Its point is about where the solution to sin is found and about the purity of the one who offers it.
The Context of 1 John 3:5
The letter of 1 John is traditionally attributed to the apostle John, and it was written to a community of believers who were facing confusion about how faith should shape daily life. Some teachers in the wider church were downplaying the seriousness of sin or claiming a special knowledge of God that did not change how people lived. John writes to correct both errors, insisting that real fellowship with God produces real holiness.
The verses just before 1 John 3:5 describe the hope that believers have in the future appearing of Christ, a hope that leads them to purify themselves as he is pure. The verses that follow spell out the contrast: those who remain in Christ do not keep on living in sin, while those who do so show that they have not truly known him. Read in that setting, the verse functions as the foundation for the call to holiness. Jesus came to deal with sin, and therefore a person who belongs to him should not treat sin as something harmless.
Key Phrases in 1 John 3:5
1 John 1:9
If we confess our sins, he is faithful and righteous to forgive us the sins, and to cleanse us from all unrighteousness.
(WEB)
This verse, earlier in the same letter, explains how forgiveness works when we confess our sins. It pairs naturally with 1 John 3:5 by showing that the removal of sin is something God does faithfully for those who come to him honestly.
John 1:29
The next day, he saw Jesus coming to him, and said, “Behold, the Lamb of God, who takes away the sin of the world!
(WEB)
John the Baptist identifies Jesus as the Lamb of God who takes away the sin of the world. The same language of removing sin appears here, and it helps you see that the purpose announced in 1 John was already part of the message about Jesus from the beginning.
A Short Prayer From 1 John 3:5
Father, thank you for sending your Son into the world to take away our sins. When I think about how much I have failed you, I am grateful that the one who came to deal with sin has no sin in him. Help me to trust his purity and to bring my guilt to him rather than hiding it. Shape my choices so that they reflect the holiness of the one who loves me. Give me honesty to confess what needs confessing and courage to walk in the light he has shown. Amen.
