First John 3:4 teaches that sin is more than breaking a rule here and there. It is a rebellion against God’s law, a refusal to live under his authority. The apostle John is writing to Christians in the late first century, churches he cares for deeply and calls “little children,” warning them about what sin really is and how it reveals whether someone truly knows God.
Everyone who sins also commits lawlessness. Sin is lawlessness.

What 1 John 3:4 Means
The verse begins with “Everyone who sins.” John is not describing a rare exception. He is describing the general pattern of sin as a human condition that touches every person who has not yet been transformed by Christ. The word he uses for sin points to missing the mark, falling short of what God intends.
Then John says sin “also commits lawlessness.” The Greek word translated lawlessness (anomia) means living without regard for God’s law or in opposition to it. Sin is not simply an accident or a weakness. It is an act that sets a person’s will against God’s will. The second sentence states the point plainly: sin is lawlessness. John is giving a definition, not offering a comment.
What the verse does not promise is that a believer will never struggle or stumble. John himself writes elsewhere that we should confess our sins, and he does not pretend Christians are sinless. The verse instead draws a clear line between a life that practices sin as its direction and a life that is aimed toward God’s righteousness.
The Context of 1 John 3:4
First John is a letter, traditionally attributed to the apostle John, written to a group of churches who knew the gospel and were being tested by false teachers. The surrounding verses, 1 John 3:1 through 3:7, begin with the wonder of being called children of God and the hope of being made like Christ when he appears. That hope is the setting for verse 4. John wants readers who expect to be like Jesus to take seriously the sin that is opposed to him.
Just after verse 4, John says that Jesus was revealed to take away sins and that in him there is no sin. Verses 6 and 7 then speak of abiding in Christ and doing righteousness. Read in this sequence, verse 4 is not a standalone harsh statement. It is the first step in a contrast between two ways of living, one shaped by lawlessness and one shaped by the righteousness that comes from Christ.
Key Phrases in 1 John 3:4
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 answers the seriousness of verse 4 with grace. Sin is lawlessness, but God is faithful and just to forgive when we confess. Reading the two together keeps the warning from turning into hopelessness.
Romans 6:1-2
1 What shall we say then? Shall we continue in sin, that grace may abound? 2 May it never be! We who died to sin, how could we live in it any longer?
(WEB)
Paul asks whether believers should continue in sin so grace may abound, and answers with a firm no. His question fits John’s concern that sin and new life in Christ cannot coexist as a settled way of living.
A Short Prayer From 1 John 3:4
Father, you have shown us what sin really is, and I confess that I have often treated it lightly. Show me where I have set my own will against yours, whether in what I do or in what I refuse to do. Thank you that your Son was revealed to take away sins. Help me bring each act of lawlessness into the light, turn from it, and walk in the righteousness that comes through him. Keep my heart near you today. Amen.
