First John 3:5 says that Jesus was revealed for one purpose, which was to take away our sins, and that there is no sin in him. The verse grounds the Christian hope in the character of Christ himself: he came to deal with sin, and he is free of it. It was written by the apostle John, traditionally identified as the author of the Gospel of John and the three letters bearing his name, to a community of believers he calls “little children” and “beloved.”
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 opens with “you know,” which tells the reader that this is not new teaching. John is reminding his readers of something they already hold. The word “revealed” points to the appearing of Jesus in human history, the incarnation and the life that followed. John is saying that this appearing had a clear aim: “to take away our sins.” The Greek sense of “take away” is closer to lifting a burden off someone’s shoulders than to simply ignoring a debt, so the picture is of Christ bearing and removing what weighed us down.
The second clause, “in him is no sin,” is a statement about who Jesus is. It is not only that he avoided sin in his conduct but that sin has no place in his nature. Because of this, he is the one qualified to take sin away. The verse does not promise that believers will never struggle with sin in this life. It explains where forgiveness comes from and what kind of person Christ is, and it sets up the rest of the passage, which describes the difference between someone who remains in Christ and someone who lives in ongoing sin.
The Context of 1 John 3:5
First John was written as a pastoral letter to Christians facing confusion and division, probably in the late first century. Some who had left the community were teaching things about Jesus and about moral living that John considered false. In that setting, a clear statement about the purpose of Christ’s coming and the sinlessness of his person gave believers a firm foundation. The verse sits in a passage that begins with the hope of being made like Christ when he appears, and it ends with the declaration that the Son of God was revealed to destroy the works of the devil.
Read in that frame, verse 5 is the hinge of the argument. Verses 2 and 3 describe the future and the present shaping effect of this hope. Verse 4 defines sin as lawlessness. Verse 5 then anchors the whole discussion in what Christ has already done and who he is. The surrounding verses keep the verse from being read as a mere comfort statement, since John’s concern throughout is that belief in Christ should show itself in a changed life.

(WEB)
John the Baptist identifies Jesus as the Lamb of God who takes away the sin of the world. The same language of taking away sin appears here, and reading it alongside First John shows that the apostle was drawing on a teaching the church had already received about who Jesus is and what he came to do.
A Short Prayer From 1 John 3:5
Lord Jesus, thank you that you were revealed in the world to take away my sins. I do not have to earn your forgiveness or hide my failures from you. You are without sin, and in you I find a Savior who can bear what I could never carry on my own. Help me to bring my failures to you honestly, to receive your cleansing with gratitude, and to walk each day in the freedom your coming has made possible. Keep me close to you, so that my life reflects the one who has taken away my sin. Amen.
