John 5:35-36

John was the lamp that kept on burning and shining [to show you the way], and you were willing for a while to rejoice in his light. [John 1:23-25] 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.
