1 John 4 New King James Version (NKJV)
Love for God and One Another
4 Beloved, do not believe every spirit, but test the spirits, whether they are of God; because many false prophets have gone out into the world. 2 By this you know the Spirit of God: Every spirit that confesses that Jesus Christ has come in the flesh is of God, 3 and every spirit that does not confess [a]that Jesus [b]Christ has come in the flesh is not of God. And this is the spirit of the Antichrist, which you have heard was coming, and is now already in the world.
4 You are of God, little children, and have overcome them, because He who is in you is greater than he who is in the world. 5 They are of the world. Therefore they speak as of the world, and the world hears them. 6 We are of God. He who knows God hears us; he who is not of God does not hear us. By this we know the spirit of truth and the spirit of error.
Knowing God Through Love
7 Beloved, let us love one another, for love is of God; and everyone who loves is born of God and knows God. 8 He who does not love does not know God, for God is love. 9 In this the love of God was manifested toward us, that God has sent His only begotten Son into the world, that we might live through Him. 10 In this is love, not that we loved God, but that He loved us and sent His Son to be the propitiation for our sins. 11 Beloved, if God so loved us, we also ought to love one another.
Seeing God Through Love
12 No one has seen God at any time. If we love one another, God abides in us, and His love has been perfected in us. 13 By this we know that we abide in Him, and He in us, because He has given us of His Spirit. 14 And we have seen and testify that the Father has sent the Son as Savior of the world. 15 Whoever confesses that Jesus is the Son of God, God abides in him, and he in God. 16 And we have known and believed the love that God has for us. God is love, and he who abides in love abides in God, and God in him.
The Consummation of Love
17 Love has been perfected among us in this: that we may have boldness in the day of judgment; because as He is, so are we in this world. 18 There is no fear in love; but perfect love casts out fear, because fear involves torment. But he who fears has not been made perfect in love. 19 We love [c]Him because He first loved us.
Obedience by Faith
20 If someone says, “I love God,” and hates his brother, he is a liar; for he who does not love his brother whom he has seen, [d]how can he love God whom he has not seen? 21 And this commandment we have from Him: that he who loves God must love his brother also.
1 John 4 Living Bible (TLB)
4 Dearly loved friends, don’t always believe everything you hear just because someone says it is a message from God: test it first to see if it really is. For there are many false teachers around, 2 and the way to find out if their message is from the Holy Spirit is to ask: Does it really agree that Jesus Christ, God’s Son, actually became man with a human body? If so, then the message is from God. 3 If not, the message is not from God but from one who is against Christ, like the “Antichrist” you have heard about who is going to come, and his attitude of enmity against Christ is already abroad in the world.
4 Dear young friends, you belong to God and have already won your fight with those who are against Christ because there is someone in your hearts who is stronger than any evil teacher in this wicked world. 5 These men belong to this world, so, quite naturally, they are concerned about worldly affairs and the world pays attention to them. 6 But we are children of God; that is why only those who have walked and talked with God will listen to us. Others won’t. That is another way to know whether a message is really from God; for if it is, the world won’t listen to it.
7 Dear friends, let us practice loving each other, for love comes from God and those who are loving and kind show that they are the children of God, and that they are getting to know him better. 8 But if a person isn’t loving and kind, it shows that he doesn’t know God—for God is love.
9 God showed how much he loved us by sending his only Son into this wicked world to bring to us eternal life through his death. 10 In this act we see what real love is: it is not our love for God but his love for us when he sent his Son to satisfy God’s anger against our sins.
11 Dear friends, since God loved us as much as that, we surely ought to love each other too. 12 For though we have never yet seen God, when we love each other God lives in us, and his love within us grows ever stronger. 13 And he has put his own Holy Spirit into our hearts as a proof to us that we are living with him and he with us. 14 And furthermore, we have seen with our own eyes and now tell all the world that God sent his Son to be their Savior. 15 Anyone who believes and says that Jesus is the Son of God has God living in him, and he is living with God.
16 We know how much God loves us because we have felt his love and because we believe him when he tells us that he loves us dearly. God is love, and anyone who lives in love is living with God and God is living in him. 17 And as we live with Christ, our love grows more perfect and complete; so we will not be ashamed and embarrassed at the day of judgment, but can face him with confidence and joy because he loves us and we love him too.
18 We need have no fear of someone who loves us perfectly; his perfect love for us eliminates all dread of what he might do to us. If we are afraid, it is for fear of what he might do to us and shows that we are not fully convinced that he really loves us. 19 So you see, our love for him comes as a result of his loving us first.
20 If anyone says “I love God,” but keeps on hating his brother, he is a liar; for if he doesn’t love his brother who is right there in front of him, how can he love God whom he has never seen? 21 And God himself has said that one must love not only God but his brother too.
