1 John 3:4

1 John 3:4, in plain English

When you sin, you're essentially saying 'no' to God's law and doing things your own way—sin and rebellion against God's order are the same thing.

Why it's here

John is cutting through any fuzzy thinking in his communities. Some people were treating sin as morally neutral or claiming they could follow Jesus while living however they wanted. He's being direct: sin isn't a small mistake or a gray area. It's opposition to God.

Who's speaking

John

Where it sits in the story

This goes back to the beginning—Adam and Eve's sin was refusing God's word and choosing their own path. Every act of sin since then carries that same DNA: 'I'll do what I want instead of what God says.'

The scholarly reading

Sin, fundamentally understood, is the violation of God's law—a refusal to align oneself with divine order.

Language and setting

John provides a theological definition of sin as ἀνομία (anomia, 'lawlessness')—not merely individual transgression but systemic rebellion against God's sovereign will. This echoes the LXX understanding of sin as rejection of God's covenant structure. The equation 'sin is lawlessness' (ἡ ἁμαρτία ἐστιν ἡ ἀνομία) employs the present indicative to assert an ontological truth rather than mere categorical relationship.

Voice

John, establishing theological foundation for the ethical imperatives to follow.

Significance

This draws from Hebrew prophetic tradition where sin constitutes covenant violation (Hosea 8:1). It prepares the argument that Christ's incarnation specifically targeted this rebellious principle—not merely forgiving individual acts but addressing humanity's fundamental orientation away from God.

2Beloved, we are now children of God, and what we will be has not yet been revealed. We know that when Christ appears, we will be like Him, for we will see Him as He is.

3And everyone who has this hope in Him purifies himself, just as Christ is pure.

4Everyone who practices sin practices lawlessness as well. Indeed, sin is lawlessness.

5But you know that Christ appeared to take away sins, and in Him there is no sin.

6No one who remains in Him keeps on sinning. No one who continues to sin has seen Him or known Him.

Read all of 1 John 3 — See what great love the Father has lavished on us — that we should be called children of God. And that is what we are. Let us love not in word but in deed.
