John 5:36-40

But I have a greater witness than John’s; for the works which the Father has given Me to finish—the very works that I do—bear witness of Me, that the Father has sent Me. And the Father Himself, who sent Me, has testified of Me. You have neither heard His voice at any time, nor seen His form. But you do not have His word abiding in you, because whom He sent, Him you do not believe. You search the Scriptures, for in them you think you have eternal life; and these are they which testify of Me. But you are not willing to come to Me that you may have life.
