1 John 4.20-5.21
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, how can he love God whom he hath not seen? 21And this commandment have we from him, That he who loveth God love his brother also. 1Whosoever believeth that Jesus is the Christ is born of God: and every one that loveth him that begat loveth him also that is begotten of him. 2By this we know that we love the children of God, when we love God, and keep his commandments. 3For this is the love of God, that we keep his commandments: and his commandments are not grievous. 4For whatsoever is born of God overcometh the world: and this is the victory that overcometh the world, even our faith.
