1. I am writing this to you, my children, so that you will not sin; but if anyone does sin, we have someone who pleads with the Father on our behalf — Jesus Christ, the righteous one.
2. And Christ himself is the means by which our sins are forgiven, and not our sins only, but also the sins of everyone.
3. If we obey God's commands, then we are sure that we know him.
4. Those who say that they know him, but do not obey his commands, are liars and there is no truth in them.
5. All those who obey his word are people whose love for God has really been made perfect. This is how we can be sure that we are in union with God:
6. those who say that they remain in union with God should live just as Jesus Christ did.
7. My dear friends, this command I am writing to you is not new; it is the old command, the one you have had from the very beginning. The old command is the message you have already heard.
8. However, the command I am now writing to you is new, because its truth is seen in Christ and also in you. For the darkness is passing away, and the real light is already shining.
9. Those who say that they are in the light, yet hate their brothers and sisters, are in the darkness to this very hour.
10. Those who love their brothers and sisters live in the light, and so there is nothing in them that will cause someone else to sin.
11. But those who hate their brothers and sisters are in the darkness; they walk in it and do not know where they are going, because the darkness has made them blind.
