God tells us to love each other

⁷ My friends, I am telling you to love one another. When I write this to you, I am not giving you a new rule. It is an old rule that you have had for a long time. We gave it to you when you began to obey Christ. It is the same message that you have already heard. ⁸ But there is something new about it. This rule has become true in the way that Christ lived. Now it has also become true in your lives. God's true message has brought light to shine in your lives. You no longer live in the dark where you do bad things. ⁹ A person may say that he is living in the light. But if that person hates another believer, then he is telling a lie. He is still living in the dark.
