No one has ever seen God, but the one and only Son, who is himself God and is in closest relationship with the Father, has made him known. (NIV)

No man has ever seen God at any time; the only unique Son, or the only begotten God, Who is in the bosom [in the intimate presence] of the Father, He has declared Him [He has revealed Him and brought Him out where He can be seen; He has interpreted Him and He has made Him known]. [Prov. 8:30.] (AMP)

No man hath seen God at any time, the only begotten Son, which is in the bosom of the Father, he hath declared him. (KJV)
