Which of you convicts me of sin? If I tell the truth, why do you not believe me?
Prove that I am guilty of sin, meaning error, falsehood, or imposture. His argument is direct: a false doctrine deserves rejection only if the man who teaches it is proven an impostor. You cannot prove this of me, so you are bound to receive my words.

I speak what I have seen with my Father, not hearsay, not hypothesis, but the exact counterpart of eternal truth itself. You do what you have seen with your father; and since there are but two families in this world, God's and the devil's, your works declare your parentage as plainly as mine declares mine.
