Then he put his hand on their eyes, saying, As your faith is, let it be done to you.

Then he touched their eyes, and said, "It will be according to your faith."

According to your faith. Though the subject of the narrative is a remarkable benefit conferred on two blind men, yet from this declaration of Christ we may draw the general doctrine, that if we pray in faith, we will never sustain a refusal in our prayers. But if those two men, whose faith was small and imperfectly formed, obtained what they wished, much more efficacious will now be the faith of those who, endued with the Spirit of adoption, and relying on the sacrifice of Christ, shah approach to God.

Then touched he their eyes - Simply to indicate that the power proceeded from him. Compare Matthew 8:3.
According to your faith - That is, you have "believed" that you could be healed, be healed accordingly. Your faith covered the whole extent of the work respecting my power and the absolute restoration to sight, and that power is exerted accordingly, and your sight is restored. So with the sinner. If he has faith in the Son of God; if he believes that he is able and willing to save him: and if he earnestly desires to be saved, the power of Jesus will be put forth to the full extent of his faith.

According to your faith - See on Matthew 8:13 (note).

Then touched he their eyes,.... Not but that he could have restored sight to them, without touching their eyes, by a word speaking, or by the secret communication of his power; but he might do this as a sign of his favour and kindness to them, and of his will to cure them; as also in compliance with their weakness, who might expect some manual operation upon them;
saying, according to your faith be it unto you: not that faith in his person and power, was the cause or condition of this cure, or the rule and measure according to which Christ proceeded; but the sense is, that as they had believed he was able to heal them, accordingly a cure should be effected; which, upon his so saying, they immediately found performed in them.

Then touched he their eyes, saying, According to your faith be it unto you--not, Receive a cure proportioned to your faith, but, Receive this cure as granted to your faith. Thus would they carry about with them, in their restored vision, a gracious seal of the faith which drew it from their compassionate Lord.

According to your faith be it unto you. Faith is the hand which takes what God offers, the spiritual organ of appropriation.
