Suppose someone claims to love God but hates a brother or sister. Then they are a liar. They don’t love their brother or sister, whom they have seen. So they can’t love God, whom they haven’t seen.
I, the elder, am writing this letter. I am sending it to the lady chosen by God and to her children. I love all of you because of the truth. I’m not the only one who loves you. So does everyone who knows the truth.
