3. That which we have seen and heard we declare to you, that ye also may have fellowship with us: and truly our fellowship is with the Father, and with his Son Jesus Christ.
4. And these things we write to you, that your joy may be full.
5. This then is the message which we have heard from him, and declare to you, that God is light, and in him is no darkness at all.

7. But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin.
