11 Friends, if this is the way God loves us, we ought to love one another like this too. 12 No one has ever seen God. However, if we love one another then God lives in us, and his love is fulfilled in us.
20 Anyone who says, "I love God," but hates a Christian brother or sister, is a liar. Anyone who doesn’t love a brother whom they can see, can’t love God whom they can’t see. 21 This is the command he gave to us: those who love God love their brothers and sisters too.
