Sheweth him— The word δεικνυσιν, rendered sheweth, has a reference here to the ample, comprehensive, and infinite knowledge which the Son has of the whole plan of the Father's counsels in all their mutual relations and dependencies. He will shew him greater works than these, "Will enable him as man, to do greater miracles than any that he has done hitherto, and which, though they may not convince, will certainly astonish you, and make it impossible for you to gainsay him, at least with any show of reason."
