that which we have seen and heard we declare to you, that you also may have fellowship with us. Yes, and our fellowship is with the Father, and with his Son, Jesus Christ.

 1:6-7 If we say that we have fellowship with him and at the same time walk in darkness, we lie and are not doing the truth. But if we walk in the light, as he is in the light, we have fellowship with each other and the blood of Jesus Christ is steadily cleansing us from all sin.
