Now we know that God heareth not sinners,.... All mankind are sinners, even God's elect; yea, such who are truly gracious and righteous persons; for there is no man without sin; and God hears such who cry unto him day and night; such Christ came to save; for such he died; and these he calls to repentance; and every penitent sinner God hears: but by "sinners" are meant notorious sinners, such in whom sin reigns, who live in sin, and particularly impostors.
The man takes up the word the Jews had made use of, and applied to Christ, Joh 9:24, and suggests, that had Jesus been a sinner, that is, an impostor, God would not have heard him, or have assisted him in doing a miracle, to support an imposture, or cover and encourage a fraud; but that he was heard and assisted, was a plain case: whereas not only they, the learned doctors of the nation, but such an illiterate man as himself knew, that notoriously wicked men, cheats, and deceivers, were not heard of God; and this was known from the Scripture, and all experience; see Ps 66:18.
The Persic and Ethiopic versions read, "I know, that God", &c.
