John 12:48-52

The one who rejects Me and does not accept My teachings has one who judges him: the word which I spoke. That will judge him on the last day.

For I did not speak on My own, but the Father Himself who sent Me has given Me a commandment as to what to say and what to speak.

And I know that His commandment is eternal life; therefore the things I speak, I speak just as the Father has told Me.”
