'Seen' in the Bible
That which was from the beginning, which we have listened to, which we have seen with our own eyes, and our own hands have handled concerning the Word of Life--
the Life was manifested, and we have seen and bear witness, and we declare unto you the Life of the Ages which was with the Father and was manifested to us--
that which we have seen and listened to we now announce to you also, in order that you also may have fellowship in it with us, and this fellowship with us is fellowship with the Father and with His Son Jesus Christ.
No one who continues in union with Him lives in sin: no one who lives in sin has seen Him or knows Him.
No one has ever yet seen God. If we love one another, God continues in union with us, and His love in all its perfection is in our hearts.
And we have seen and bear witness that the Father has sent the Son to be the Saviour of the world.
If any one says that he loves God, while he hates his brother man, he is a liar; for he who does not love his brother man whom he has seen, cannot love God whom he has not seen.
