John 12:48-50
12:48 The one who rejects me and does not accept my words has a judge; the word I have spoken will judge him at the last day.
12:49 For I have not spoken from my own authority, but the Father himself who sent me has commanded me what I should say and what I should speak.
12:50 And I know that his commandment is eternal life. Thus the things I say, I say just as the Father has told me.”
