First John 3:5 tells us that Jesus appeared in order to remove our sins, and that there is no sin in him. The verse is a statement about Christ’s purpose and character, written by the apostle John to believers who needed to be reminded who Jesus is and why he came. John writes to his “little children,” the Christian community he has been teaching throughout the letter.
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 you John is not introducing something new. He is pointing back to what his readers have already been taught about Jesus. The word “revealed” means made visible or made known. Jesus did not simply exist in a distant heaven. He was seen, heard, and touched in history, and the purpose of that appearing was “to take away our sins.” John is describing the reason for the Incarnation in one clear line.
The second half, “in him is no sin,” makes a claim about Jesus’s own nature. He is not partly good and partly flawed. Nothing in him falls short of God’s holiness. The verse does not promise that believers will never struggle with sin. Its focus is Christ: he came to deal with sin, and he himself is free from it. That is the foundation John builds on in the verses that follow.
The Context of 1 John 3:5
First John is a letter rather than a gospel, and it was written to a group of believers facing teaching that minimized sin or denied that Jesus came in real human flesh. Tradition ascribes the letter to the apostle John, the disciple who spent his life in the churches of Asia Minor. His tone is pastoral and direct, and he repeatedly contrasts light with darkness, love with hatred, and truth with deception.
Verses 2 through 8 form a single argument. John first speaks of the hope of being made like Christ (verses 2 and 3), then warns that sin is lawlessness (verse 4), and then gives verse 5 as the reason his readers should take sin seriously: Jesus came to remove it. Verses 6 through 8 draw the conclusion that someone who keeps living in sin does not know Christ. Read that way, verse 5 is the hinge of the passage. It is the reason John’s warnings and encouragements fit together.

A Short Prayer From 1 John 3:5
Lord Jesus, thank you that you came into this world to take away my sins. I confess that I do not always live as though that matters. Forgive me for the things I have hidden, excused, or repeated. Help me to see sin as you see it, and to trust you to lift its weight from my life. Let your purity be the pattern I reach for each day. Amen.
