3. We announce to you what we have seen and heard. We do it so you can share life together with us. And we share life with the Father and with his Son, Jesus Christ.
4. We are writing this to make our joy complete.
5. Here is the message we have heard from him and announce to you. God is light. There is no darkness in him at all.
6. Suppose we say that we share life with God but still walk in the darkness. Then we are lying. We are not living by the truth.
7. But suppose we walk in the light, just as he is in the light. Then we share life with one another. And the blood of Jesus, his Son, makes us pure from all sin.
