7Beloved, let us love one another; because love is of God, and every one that loves has been begotten of God, and knows God. 8He that loves not has not known God; for God is love. 9Herein as to us has been manifested the love of God, that God has 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 a propitiation for our sins. 11Beloved, if God has so loved us, we also ought to love one another. 12No one has seen God at any time: if we love one another, God abides in us, and his love is perfected in us. 13Hereby we know that we abide in him and he in us, that he has given to us of his Spirit. 14And we have seen, and testify, that the Father has sent the Son as Saviour of the world. 15Whosoever shall confess that Jesus is the Son of God, God abides in him, and he in God. 16And we have known and have believed the love which God has to us. God is love, and he that abides in love abides in God, and God in him. 17Herein has love been perfected with us that we may have boldness in the day of judgment, that even as he is, we also are in this world. 18There is no fear in love, but perfect love casts out fear; for fear has torment, and he that fears has not been made perfect in love. 19We love because he has first loved us. 20If any one say, I love God, and hate his brother, he is a liar: for he that loves not his brother whom he has seen, how can he love God whom he has not seen? 21And this commandment have we from him, That he that loves God love also his brother.
