'Seen' in the Bible

That which was from the beginning, that which we have heard, that which we have seen with our eyes, that which we beheld, and our hands handled, concerning the Word of life

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

that which we have seen and heard declare we unto you also, that ye also may have fellowship with us: yea, and 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 knoweth him.

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, cannot love God whom he hath not seen.
