| 1Dear friends, stop believing every spirit. Instead, test the spirits to see whether they are from God, because many false prophets have gone out into the world. | 1Dear friends, do not believe every spirit, but test the spirits to determine if they are from God, because many false prophets have gone out into the world. |
| 2This is how you can recognize God's Spirit: Every spirit who acknowledges that Jesus the Messiah has become human—and remains so—is from God. | 2By this you know the Spirit of God: Every spirit that confesses Jesus as the Christ who has come in the flesh is from God, |
| 3But every spirit who does not acknowledge Jesus is not from God. This is the spirit of the antichrist. You have heard that he is coming, and now he is already in the world. | 3but every spirit that does not confess Jesus is not from God, and this is the spirit of the antichrist, which you have heard is coming, and now is already in the world. |

By this we know the Spirit of truth and the spirit of deceit. |

| 8The person who does not love does not know God, because God is love. | 8The person who does not love does not know God, because God is love. |
| 9This is how God's love was revealed among us: God sent his unique Son into the world so that we might live through him. | 9By this the love of God is revealed in us: that God has sent his one and only Son into the world so that we may live through him. |
| 10This is love: not that we have loved God, but that he loved us and sent his Son to be the atoning sacrifice for our sins. | 10In this is love: not that we have loved God, but that he loved us and sent his Son to be the atoning sacrifice for our sins. |
| 11Dear friends, if this is the way God loved us, we must also love one another. | 11Dear friends, if God so loved us, then we also ought to love one another. |
| 12No one has ever seen God. If we love one another, God lives in us, and his love is perfected in us. | 12No one has seen God at any time. If we love one another, God resides in us, and his love is perfected in us. |
| 13This is how we know that we abide in him and he in us: he has given us his Spirit. | 13By this we know that we reside in God and he in us: in that he has given us of his Spirit. |

| 16We have come to know and rely on the love that God has for us. God is love, and the person who abides in love abides in God, and God abides in him. | 16And we have come to know and to believe the love that God has in us. God is love, and the one who resides in love resides in God, and God resides in him. |
| 17This is how love has been perfected among us: we will have confidence on the day of judgment because, during our time in this world, we are just like him. | 17By this love is perfected with us, so that we may have confidence in the day of judgment, because just as Jesus is, so also are we in this world. |
| 18There is no fear where love exists. Rather, perfect love banishes fear, for fear involves punishment, and the person who lives in fear has not been perfected in love. | 18There is no fear in love, but perfect love drives out fear, because fear has to do with punishment. The one who fears punishment has not been perfected in love. |
| 19We love because God first loved us. | 19We love because he loved us first. |
| 20Whoever says, "I love God," but hates his brother is a liar. The one who does not love his brother whom he has seen cannot love the God whom he has not seen. | 20If anyone says "I love God" and yet hates his fellow Christian, he is a liar, because the one who does not love his fellow Christian whom he has seen cannot love God whom he has not seen. |
| 21And this is the commandment that we have from him: the person who loves God must also love his brother. | 21And the commandment we have from him is this: that the one who loves God should love his fellow Christian too. |
