John 5:35-39

He was a burning and a shining light: and ye were willing for a season to rejoice in his light.

But I have greater witness than that of John: for the works which the Father hath given me to finish, the same works that I do, bear witness of me, that the Father hath sent me.

And the Father himself, which hath sent me, hath borne witness of me. Ye have neither heard his voice at any time, nor seen his shape.

And ye have not his word abiding in you: for whom he hath sent, him ye believe not.

Search the scriptures; for in them ye think ye have eternal life: and they are they which testify of me.
