19 We love, because he first loved us. 20 If any one says, “I love God,” and hates his brother, he is a liar; for he who does not love his brother whom he has seen, cannot* love God whom he has not seen. 21 And this commandment we have from him, that he who loves God should love his brother also.

Chapter 5

1 Every one who believes that Jesus is the Christ is a child of God, and every one who loves the parent loves the child. 2 By this we know that we love the children of God, when we love God and obey his commandments. 3 For this is the love of God, that we keep his commandments. And his commandments are not burdensome. 4 For whatever is born of God overcomes the world; and this is the victory that overcomes the world, our faith.
