John 5:36-37

But the testimony which I have is far greater than the testimony of John; for the works that the Father has given Me to finish—the very same works [that is, the miracles and proofs of My deity] that I am [now] doing—testify about Me, [by providing evidence] that the Father has sent Me. And the Father who sent Me has Himself testified about Me. You have never heard His voice nor seen His form [His majesty and greatness—what He is like].
