1 John 4:21

19 We love because He first loved us.

20 If anyone says, “I love God,” but hates his brother, he is a liar. For anyone who does not love his brother, whom he has seen, cannot love God, whom he has not seen.

And we have this commandment from Him: Whoever loves God must love his brother as well.

Do read the surrounding verses too, because the context often says more than a single verse.
