Summary: John emphasizes the truth of the Word of Life and invites the reader to join in the fellowship with the Father and Jesus Christ. The author's aim is to complete their joy by sharing this message.
Beloved:
What was from the beginning, what we have heard, what we have seen with our eyes, what we looked upon and touched with our hands concerns the Word of life – for the life was made visible; we have seen it and testify to it and proclaim to you the eternal life that was with the Father and was made visible to us – what we have seen and heard we proclaim now to you, so that you too may have fellowship with us; for our fellowship is with the Father and with his Son, Jesus Christ.
We are writing this so that our joy may be complete.
