John 8:46

Which of you convinceth me of sin? - Do you pretend to reject the truths which I announce, because my life does not correspond to the doctrines I have taught? But can any of you prove me guilty of any fault? You have maliciously watched all my steps; have you seen the smallest matter to reprove, in any part of my conduct?

But it is probable that ἁμαρτια, sin, is put here in opposition to αληθεια, truth, in the same verse, and then it should be rendered falsehood. The very best Greek writers use the word in the same sense: this, Kypke proves by quotations from Polybius, Lucian, Dionysius Halicarnassensis, Plutarch, Thucydides, and Hippocrates. Raphelius adds a pertinent quotation from Herodotus, and shows that the purest Latin writers have used the word peccatum, sin, in the sense of error or falsehood. See the note on Genesis 13:13.

Which of you convinceth me? - To convince, with us, means to satisfy a man's own mind of the truth of anything; but this is not its meaning here. It rather means to convict. Which of you can prove that I am guilty of sin?

Of sin - The word "sin" here evidently means "error, falsehood, or imposture." It stands opposed to truth. The argument of the Saviour is this: A doctrine might be rejected if it could be proved that he that delivered it was an impostor; but as you cannot prove this of me, you are bound to receive my words.

8:46 Which of you convicteth me of sin? - And is not my life as unreprovable as my doctrine? Does not my whole behaviour confirm the truth of what I teach?
