'Seen' in the Bible

That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon, and our hands have handled, of the Word of life;

(For the life was manifested, and we have seen it, and bear witness, and shew unto you that eternal life, which was with the Father, and was manifested unto us;)

That which we have seen and heard declare we unto you, that ye also may have fellowship with us: and truly our fellowship is with the Father, and with his Son Jesus Christ.

Whosoever abideth in him sinneth not: whosoever sinneth hath not seen him, neither known him.

No man hath seen God at any time. If we love one another, God dwelleth in us, and his love is perfected in us.

And we have seen and do testify that the Father sent the Son to be the Saviour of the world.

If a man say, I love God, and hateth his brother, he is a liar: for he that loveth not his brother whom he hath seen, how can he love God whom he hath not seen?
