11 Beloved, if God so loved us, we also ought to love one another. 12 No man has ever seen God; if we love one another, God abides in us and his love is perfected in us.

13 By this we know that we abide in him and he in us, because he has given us of his own Spirit. 14 And we have seen and testify that the Father has sent his Son as the Savior of the world. 15 Whoever confesses that Jesus is the Son of God, God abides in him, and he in God. 16 So we know and believe the love God has for us. God is love, and he who abides in love abides in God, and God abides in him.
