MSB(i)
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, how can he love God, whom he has not seen?
21 And we have this commandment from Him: Whoever loves God must love his brother as well.
5 1 Everyone who believes that Jesus is the Christ has been born of God, and everyone who loves the Father also loves those born of Him.
2 By this we know that we love the children of God: when we love God and keep His commandments.
