After that he put his hands again upon his eyes, and made him {g} look up: and he was restored, and saw every man clearly.

(g) He commanded him to try again, to determine whether or not he could indeed see well.

People's New Testament

8:25 He put his hands again upon his eyes. This is the only example of a progressive cure. I suppose that it was an example of progressive faith. The Lord could have healed him with a word, but he wished to save the soul as well as the body.

Jamieson-Fausset-Brown Bible Commentary

25. After that he put his hands again upon his eyes, and made him look up; and he was restored, and saw every man clearly-Perhaps the one operation perfectly restored the eyes, while the other imparted immediately the faculty of using them. It is the only recorded example of a progressive cure, and it certainly illustrates similar methods in the spiritual kingdom. Of the four recorded cases of sight restored, all the patients save one either came or were brought to the Physician. In the case of the man born blind, the Physician came to the patient. So some seek and find Christ; of others He is found who seek Him not.

Matthew Henry's Concise Commentary

8:22-26 Here is a blind man brought to Christ by his friends. Therein appeared the faith of those that brought him. If those who are spiritually blind, do not pray for themselves, yet their friends and relations should pray for them, that Christ would be pleased to touch them. The cure was wrought gradually, which was not usual in our Lord's miracles. Christ showed in what method those commonly are healed by his grace, who by nature are spiritually blind. At first, their knowledge is confused; but, like the light of the morning, it shines more and more to the perfect day, and then they see all things clearly. Slighting Christ's favours is forfeiting them; and he will make those who do so know the worth of privileges by the want of them.
