1 John 4

Beloved, don’t believe every spirit, but test the spirits, whether they are of God, because many false prophets have gone out into the world.

By this you know the Spirit of God: every spirit who confesses that Jesus Christ has come in the flesh is of God,

and every spirit who doesn’t confess that Jesus Christ has come in the flesh is not of God; and this is the spirit of the Antichrist, of whom you have heard that it comes. Now it is in the world already.

You are of God, little children, and have overcome them, because greater is he who is in you than he who is in the world.

They are of the world. Therefore they speak of the world, and the world hears them.

We are of God. He who knows God listens to us. He who is not of God doesn’t listen to us. By this we know the spirit of truth, and the spirit of error.

Beloved, let’s love one another, for love is of God; and everyone who loves has been born of God and knows God.

He who doesn’t love doesn’t know God, for God is love.

By this God’s love was revealed in us, that God has sent his only born Son into the world that we might live through him.

In this is love, not that we loved God, but that he loved us, and sent his Son as the atoning sacrifice for our sins.

Beloved, if God loved us in this way, we also ought to love one another.

No one has seen God at any time. If we love one another, God remains in us, and his love has been perfected in us.

By this we know that we remain in him and he in us, because he has given us of his Spirit.

We have seen and testify that the Father has sent the Son as the Savior of the world.

Whoever confesses that Jesus is the Son of God, God remains in him, and he in God.

We know and have believed the love which God has for us. God is love, and he who remains in love remains in God, and God remains in him.

In this, love has been made perfect among us, that we may have boldness in the day of judgment, because as he is, even so we are in this world.

There is no fear in love; but perfect love casts out fear, because fear has punishment. He who fears is not made perfect in love.

We love him, because he first loved us.

If a man says, “I love God,” and hates his brother, he is a liar; for he who doesn’t love his brother whom he has seen, how can he love God whom he has not seen?

This commandment we have from him, that he who loves God should also love his brother.

Chapter overviewAI-generated

Overview.
This chapter calls believers to discern true spiritual reality by testing the spirits through the confession of Jesus Christ’s incarnate mission, grounding Christian love in God’s own nature and self-revelation in Christ, and showing how love perfected among the community confirms their union with God.

Flow.

Begins with a warning to test spiritual influences, identifying the confession of Jesus Christ come in the flesh as the mark of the Spirit of God, contrasted with the spirit of the Antichrist already at work.
Affirms the believers’ victory through the indwelling Spirit, distinguishing the worldly voices from the apostolic witness grounded in God’s truth.
Shifts to the theme of love, rooting it in God’s very being and revealed definitively in the sending of His Son as atoning sacrifice.
Concludes by binding love for God to tangible love for fellow believers, warning that hatred toward a brother invalidates claims to love God.

Connections.
Following chapter 3, which established love as a defining mark of those who have passed from death to life through God’s fatherly gift of new birth, this chapter expands on what such love entails in both doctrinal fidelity and communal practice. It deepens the test of genuine faith by linking right confession of Christ with the Spirit’s presence and the inevitable outworking of divine love among God’s people. Where chapter 3 emphasized ethical transformation, chapter 4 grounds it in theological truth and Spirit-wrought communion. This prepares the way for chapter 5, which unites these themes in affirming faith in Christ as Son of God, the witness of the Spirit, water, and blood, and the victory of faith over the world.

What it teaches.
True faith is marked by doctrinal fidelity and spiritual discernment: the Spirit of God confesses the incarnate Son, while the spirit of error denies Him (WCF 8.6; 2LCF 8.6). Believers overcome error because the indwelling Spirit is greater than the powers of the present age (WCF 13.2). Love is not merely human affection but originates in God’s own nature and redemptive initiative: He loved first, sent His Son as propitiation, and thus made known His love (WCF 8.5; ). To abide in God is to abide in love, demonstrated by mutual love among believers, without which no one can claim to know God (, 20; HC LD 10). Assurance of salvation is strengthened as love is perfected in community, casting out fear because believers participate in Christ’s righteousness (WCF 18.1; HC LD 32).

Apply.
Love your brother in practical ways, recognizing that such love is both a sign of God's presence and a testimony to His love fulfilled among you.
