(10) How were thine eyes opened?--They wonder at the change wrought in him, and seek to know how it happened. The question is important if we adopt the better reading, beggar, for "blind," in John 9:8, as showing that they knew he had been blind, the moment they knew that he was the same person who used to sit and beg.

Verse 10. - They said therefore to him, How then were thine eyes opened? If you are the very man, how has this come about?

9:8-12 Those whose eyes are opened, and whose hearts are cleansed by grace, being known to be the same person, but widely different in character, live as monuments to the Redeemer's glory, and recommend his grace to all who desire the same precious salvation. It is good to observe the way and method of God's works, and they will appear the more wonderful. Apply this spiritually. In the work of grace wrought upon the soul we see the change, but we see not the hand that makes it: the way of the Spirit is like that of the wind, which thou hearest the sound of, but canst not tell whence it comes, nor whither it goes.Therefore said they unto him,.... When the case was clear, and it was out of question that he was the man:

how were thine eyes opened? or made to see: they might well ask this question, since such a thing was never known before, that one born blind received his sight; and as great a miracle it is in grace, and as great a mystery to a natural man, how one should be born again, or be spiritually enlightened.
