BIBLE CHAPTER STUDY
1 John 4 — Testing the Spirits and God Is Love
A pastoral instruction to test the spirits by confessing Christ come in the flesh, paired with the thesis that God is love and that such love is demonstrated by the Father's sending of the Son and is perfected in mutual love among believers.
Scripture
1Beloved, believe not every spirit, but prove the spirits, whether they are of God; because many false prophets are gone out into the world.
2Hereby know ye the Spirit of God: every spirit that confesseth that Jesus Christ is come in the flesh is of God:
3and every spirit that confesseth not Jesus is not of God: and this is the spirit of the antichrist, whereof ye have heard that it cometh; and now it is in the world already.
4Ye are of God, my little children, and have overcome them: because greater is he that is in you than he that is in the world.
5They are of the world: therefore speak they as of the world, and the world heareth them.
6We are of God: he that knoweth God heareth us; he who is not of God heareth us not. By this we know the spirit of truth, and the spirit of error.
7Beloved, let us love one another: for love is of God; and every one that loveth is begotten of God, and knoweth God.
8He that loveth not knoweth not God; for God is love.
9Herein was the love of God manifested in us, that God hath sent his only begotten Son into the world that we might live through him.
10Herein is love, not that we loved God, but that he loved us, and sent his Son to be the propitiation for our sins.
11Beloved, if God so loved us, we also ought to love one another.
12No man hath beheld God at any time: if we love one another, God abideth in us, and his love is perfected in us:
13hereby we know that we abide in him and he in us, because he hath given us of his Spirit.
14And we have beheld and bear witness that the Father hath sent the Son to be the Saviour of the world.
15Whosoever shall confess that Jesus is the Son of God, God abideth in him, and he in God.
16And we know and have believed the love which God hath in us. God is love; and he that abideth in love abideth in God, and God abideth in him.
17Herein is love made perfect with us, that we may have boldness in the day of judgment; because as he is, even so are we in this world.
18There is no fear in love: but perfect love casteth out fear, because fear hath punishment; and he that feareth is not made perfect in love.
19We love, because he first loved us.
20If a man say, I love God, and hateth his brother, he is a liar: for he that loveth not his brother whom he hath seen, cannot love God whom he hath not seen.
21And this commandment have we from him, that he who loveth God love his brother also.
What this passage means
Verses 1–6 form the first half of the chapter and deal with discernment. The community is told not to believe every spirit but to test them, because many false prophets have gone out into the world. The stated test is christological: every spirit that confesses that Jesus Christ has come in the flesh is of God, and every spirit that does not confess Jesus is not of God, identified as the spirit of the antichrist already in the world. The writer then addresses his readers as "little children," declares that the one in them is greater than the one in the world, and grounds certainty of true fellowship in hearing the apostolic witnesses (verses 4–6).
Verses 7–12 pivot from discernment to definition. The recurring imperative "let us love one another" is grounded in the statement that love is of God, that the one who loves has been begotten of God and knows God, and that the one who does not love has not known God "because God is love." The display of that love is given concretely: God sent his only-begotten Son into the world that believers might live through him (verse 9), and love is defined not as human initiative toward God but as God's prior action—sending the Son as the propitiation for sins (verse 10). Mutual love among believers is therefore a necessary outflow and a place where the unseen God abides (verse 12).
Verses 13–21 extend the theme of mutual indwelling. The gift of the Spirit and the apostolic witness to the Father sending the Son certify that God abides in the believer (verses 13–15). The confession "God is love" is paired with "he that abideth in love abideth in God," and such perfected love yields boldness on the day of judgment because the believer's manner of life now matches Christ's (verse 17). Because fear involves punishment, perfect love casts it out (verse 18). The chapter closes with a concrete test: claiming to love God while hating a brother whom one has seen is exposed as a lie, since love for the unseen God cannot coexist with hatred of the visible brother (verses 20–21).
Context
The chapter is unified by the curated chapter note "God is love," which corresponds to the explicit declaration of verse 8 and verse 16 and frames the entire discussion. The chapter continues themes from earlier in 1 John (the tests of fellowship, righteousness, and confession) but here concentrates on the source of genuine love. The mention of the spirit of the antichrist already in the world (verse 3) and the warning about false prophets (verse 1) tie this passage to the broader Johannine concern over competing christological claims. The cross references supplied (for example 1 John 4:10 and 1 John 4:16) show that the passage itself is internally cross-referenced, indicating that the writer is repeating and developing his key propositions.
Key words in the original
- G1381 Used in verse 1 with the gloss "to test (literally or figuratively); by implication, to approve." The context supports both senses: testing exposes which spirits are of God, and those that pass are thereby approved.
- G0500 The lemma ἀντίχριστος (verse 3) labels the opposing spirit as 'antichrist,' paralleling the Johannine usage already introduced earlier in the letter. The chapter treats this as a present reality rather than a future figure.
- G5578 ψευδοπροφήται in verse 1 means 'spurious prophet; pretended foreteller or religious impostor.' They are the human channel through which false spirits operate and ground the command to test the spirits.
Related verses
- 1 John 4:10 This self-reference shows the writer's deliberate repetition: the sending of the Son as propitiation is the defining act of love that grounds the imperative to love one another.
- 1 John 4:16 A second internal citation reiterating the central thesis "God is love" and the mutual indwelling formula, confirming that the chapter's center of gravity is in verses 7–21 rather than the opening discernment section.
- 1 John 4:12 This reference marks the hinge between the definition of love (7–11) and the discussion of perfected love and mutual indwelling (13–21), centering on the claim that the unseen God abides where believers love one another.
Common questions
How does 1 John 4 test the spirits?
By a christological confession: the spirit that confesses that Jesus Christ has come in the flesh is of God, and the spirit that does not confess Jesus is not of God (verses 2–3).
What does the chapter mean by "God is love"?
It defines God's character, demonstrated in sending his Son as the propitiation for sins (verse 10), and shows that love is sourced in God rather than originating in believers, who love because he first loved them (verse 19).
Why does the chapter connect love for God with love for a brother?
Because claiming to love the unseen God while hating a visible brother is a lie (verse 20), and the closing commandment makes love for the brother the practical test of love for God (verse 21).
