What meaneth this, In whom is no guile? Had he no sin? Was no physician necessary for him? Far from it. No one was ever born, of a temper not to need the Physician. It is guile, when we say one thing, and think another. How then was there no guile in him? Because, if he was a sinner, he confessed his sin; whereas if a man, being a sinner, pretends to be righteous, there is guile in his mouth. Our Lord then commended the confession of sin in Nathanael; He did not pronounce him not a sinner.
