We proclaim to you the one who existed from the beginning, whom we have heard and seen. We saw him with our own eyes and touched him with our own hands. He is the Word of life. This one who is life itself was revealed to us, and we have seen him. And now we testify and proclaim to you that he is the one who is eternal life. He was with the Father, and then he was revealed to us. We proclaim to you what we ourselves have actually seen and heard so that you may have fellowship with us. And our fellowship is with the Father and with his Son, Jesus Christ. We are writing these things so that you may fully share our joy.
This is the message we heard from Jesus and now declare to you: God is light, and there is no darkness in him at all. So we are lying if we say we have fellowship with God but go on living in spiritual darkness; we are not practicing the truth. But if we are living in the light, as God is in the light, then we have fellowship with each other, and the blood of Jesus, his Son, cleanses us from all sin.
