First John 3:5 tells us that Jesus appeared in order to remove our sins, and that there is no sin in him at all. The verse is a statement about the purpose of Christ’s coming and about his own character. It is written by the apostle John, who speaks as an elder to a group of Christian believers in the early church, addressing them with the warmth of a pastor writing to people he loves.
You know that he was revealed to take away our sins, and in him is no sin.

What 1 John 3:5 Means
The verse begins with “You know,” which tells us John is not teaching something new. He is reminding his readers of what they have already been taught and what they have experienced. The word “revealed” points to the moment when Jesus became visible in human history, first in his incarnation and then through his life, death, and resurrection. John’s point is that the Son of God was made manifest for a specific reason: “to take away our sins.”
The second half of the verse makes a claim about Jesus himself: “in him is no sin.” This is not simply a statement that Jesus avoided wrongdoing. It describes the very nature of who he is. Because Christ is without sin, he is able to deal with sin on behalf of others. Notice that the verse does not promise that believers will stop sinning on their own strength. It points us to Jesus as the one who deals with the problem, and to his sinlessness as the foundation of our hope.
The Context of 1 John 3:5
This letter was written to a community of believers who were facing confusion about what it meant to live as children of God. Verses 2 and 3 look forward to the day we will be like Christ, and they call every believer to purify themselves in response to that hope. Verse 4 defines sin as lawlessness, which sets up the contrast that John develops in verse 5. The Son was revealed to deal with exactly that lawlessness.
Reading verse 5 within this passage changes how it sounds. It is not a detached theological statement but a grounding reason for the moral seriousness John calls for. Because Jesus came to remove sin and has none himself, his followers have every reason to take sin seriously and to live in the light of his purpose. The verses that follow, which warn against being led astray and describe the devil’s works, make sense only against this backdrop.
