Jesus answered, Neither hath this man sinned, nor his parents — It was not the manner of our Lord to answer any questions that were of no use, but to gratify an idle curiosity. Therefore he determines nothing concerning this. The scope of his answer is, It was neither for any sins of his own, nor yet of his parents; but that the power of God might be displayed.
