God abides in those who confess that Jesus is the Son of God, and they abide in God. So we have known and believe the love that God has for us. (1 John 4:15-16a, NRSV)
God lives in us when we love one another and confess that Jesus is the Son of God. Some may say that these two things are two completely different things. But I say that you confess that Jesus is God’s Son when you love one another. Because the love we have comes from and comes to us by Jesus coming and living among us and showing us how to live and love each other. You see we get God’s love through Jesus and if we love one another we are proclaiming that Jesus is the Son of God, and if we do not love one another we are confessing we do not believe Jesus is God’s Son.
So is Jesus God’s Son, and do you love one another?
By this we know that we abide in him and he in us, because he has given us of his Spirit. And we have seen and do testify that the Father has sent his Son as the Savior of the world. (1 John 4:13-14, NRSV)
Beloved, since God loved us so much, we also ought to love one another.No one has ever seen God; if we love one another, God lives in us, and his love is perfected in us. (1 John 4:11-12, NRSV)
Beloved, let us love one another because love is from God; everyone who loves is born of God and knows God. Whoever does not love does not know God, for God is love. God’s love was revealed among us in this way: God sent his only Son into the world so that we might live through him. In this is love, not that we loved God but that he loved us and sent his Son to be the atoning sacrifice for our sins. (1 John 4:7-10, NRSV)
Beloved, do not believe every spirit, but test the spirits to see whether they are from God; for many false prophets have gone out into the world. By this you know the Spirit of God: every spirit that confesses that Jesus Christ has come in the flesh is from God, and every spirit that does not confess Jesus is not from God. And this is the spirit of the antichrist, of which you have heard that it is coming; and now it is already in the world. Little children, you are from God, and have conquered them; for the one who is in you is greater than the one who is in the world. They are from the world; therefore what they say is from the world, and the world listens to them. We are from God. Whoever knows God listens to us, and whoever is not from God does not listen to us. From this we know the spirit of truth and the spirit of error. (1 John 4:1-6, NRSV)
And this is his commandment, that we should believe in the name of his Son Jesus Christ and love one another, just as he has commanded us. All who obey his commandments abide in him, and he abides in them. And by this we know that he abides in us, by the Spirit that he has given us. (1 John 3:23-24, NRSV)
Little children, let us love, not in word or speech, but in truth and action. And by this we will know that we are from the truth and will reassure our hearts before him whenever our hearts condemn us; for God is greater than our hearts, and he knows everything. Beloved, if our hearts do not condemn us, we have boldness before God; and we receive from him whatever we ask, because we obey his commandments and do what pleases him. (1 John 3:18-22, NRSV)
