ESVEnglish Standard Version
19We love because he first loved us. 20If anyone 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. 21And this commandment we have from him: whoever loves God must also love his brother.
