1 John 4:7-21
"Beloved, let us love one another: for love is of God; and every one that loveth is born of God , and knoweth God. He that loveth not knoweth not God; for God is love. In this was manifested the love of God toward us, because that God sent his only begotten Son into the world, that we might live through Him. Herein is love not that we loved God, but that He loved us, and sent His Son to be the propitiation for our sins. Beloved, if God so loved us, we ought also to love one another. No man hath seen God at any time. If we love one another, God dwelleth in us, and His love is perfected in us. Hereby know we that we dwell in Him and He in us, because he hath given us of His Spirit. And we have seen and do testify that the Father sent the Son to be the Saviour of the world. Whosoever shall confess that Jesus is the Son of God, God dwelleth in Him, and He in God. And we have known and believed the love that God hath to us. God is love: and he that dwelleth in love dwelleth in God, and God in him. Herein is our love made perfect, that we may have boldness in the day of judgement: because as He is, so are we in this world. There is no fear in love: but perfect love casteth out fear: because fear hath torment. He that feareth is not made perfect in love. We love Him, because He first loved us.
If 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, how can he love God whom he hath not seen? And this commandment have we from Him, That he who loveth God loveth his brother also."
