7Beloved, let us love one another: for love is of God; and every one that loveth is begotten of God, and knoweth God. 8He that loveth not knoweth not God; for God is love. 9Herein was the love of God manifested in us, that God hath 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 to be the propitiation for our sins. 11Beloved, if God so loved us, we also ought to love one another. 12No man hath beheld God at any time: if we love one another, God abideth in us, and his love is perfected in us: 13hereby know we that we abide in him, and he in us, because he hath given us of his Spirit. 14And we have beheld and bear witness that the Father hath sent the Son to be the Saviour of the world. 15Whosoever shall confess that Jesus is the Son of God, God abideth in him, and he in God. 16And we know and have believed the love which God hath in us. God is love; and he that abideth in love abideth in God, and God abideth in him. 17Herein is love made perfect with us, that we may have boldness in the day of judgement; because as he is, even so are we in this world. 18There is no fear in love: but perfect love casteth out fear, because fear hath punishment; and he that feareth is not made perfect in love. 19We love, because he first loved us. 20If a man say, I love God, and hateth his brother, he is a liar: for he that loveth not his brother whom he hath seen, cannot love God whom he hath not seen. 21And this commandment have we from him, that he who loveth God love his brother also.
